OPERATION


4/25

VOLUME

Rotate the volume control clockwise past the"click" to turn the TX3400 on. Adjust thevolume control for a comfortable listening level.

If no sound is heard, temporarily unmute the

radio by briefly pressing the SQL key. You cannow adjust the volume by listening to thereceiver's background noise. When finished,briefly press the SQL key again to re-mute theradio.

BACK LIGHTING

The Liquid Crystal Display and function keysare backlit for easy viewing at night or in lowlight situations. The back lighting is on at all

times while the TX3400 is turned on.

SELECTING CHANNELS

Select the required channel by rotating thechannel selector knob. Rotate the knobclockwise to select higher channels andcounter-clockwise to select lower channels.The selected channel is displayed on the LCD.

SQUELCH

The squelch is used to eliminate any annoyingbackground noise when there are no signalspresent. The TX3400 features a preset squelchsystem. The squelch level has been set toprovide optimum performance.

The Squelch can be Opened or Closed with theSQL key. When the Squelch is Open, thereceiver's background noise can be heard and'BUSY' is displayed. When the Squelch is

closed, the receiver remains quiet when thereare no signals present but any incoming signalswill override the Squelch and be heard in thespeaker.

To open the Squelch, briefly press the SQL key.A low beep will be heard. If there are no signalspresent you will hear the receiver's backgroundnoise.

To close the Squelch, briefly press the SQL key

again. A high beep will be heard and thereceiver will become quiet.

NOTE: If an incoming signal is very weak and isclose to the minimum squelch level, it maybecome broken or chopped by the squelchaction. To prevent this, simply open the squelchto allow the signal to be heard clearly.Alternatively, you can reduce the squelchsensitivity as described below.

Setting the Squelch Sensitivity.

The sensitivity of the squelch to incomingsignals can be set to suit your operatingenvironment. The TX3400 has three presetsquelch sensitivity settings which can beselected using a front panel key sequence.

SQL1: Maximum Sensitivity.The squelch will open even on very weak

signals. This is the best setting for quietcountry or rural locations where there arevery few weak stations or l i tt le locallygenerated interference.

SQL2: Medium Sensitivity.The squelch will open on most signals, butwill not be as sensitive to very weak signalsor local interference. Suitable for general orsuburban use.

SQL3: Minimum Sensitivity.The squelch will open on reasonably strongsignals and weak signals will not be heard.Suitable for inner city applications or areasof severe interference.

To pre-select the squelch sensitivity.

1. Turn the TX3400 OFF at the Volume control.

2. Hold the DUP and SQL keys while turning

the unit back on again.

3. Rotate the Channel switch to select SQL1,SQL2 or SQL3.

4. Turn the unit OFF again to store the setting.

DUPLEX SWITCH

Duplex operation allows the TX3400 to transmiton a different frequency to that which it

receives. This allows operation through anyrepeater stations in your area. Repeaters

4


5/25

automatically re-transmit your signal over awider area, providing greatly increased range.

The Duplex function operates only on channels1 - 8. When Duplex is selected on one of thesechannels, the TX3400 receives on that channelbut actually transmits 30 channels higher.

E.g.

The TX3400 allows you to select duplexoperation on individual channels. This isparticularly useful in country areas where there

may only be one or two repeaters. Thenunused repeater channels can be used fornormal simplex or direct radio-to-radiocommunications.

To select Duplex on individual channels:

1. Select the required channel 1 - 8.

2. Briefly press the DUP key. DUP will appearon the display accompanied by a high beep.

To remove Duplex from a channel:

1. Select the required channel 1 - 8. DUP willbe visible on the display.

2. Briefly press the DUP key. DUP wi l ldisappear from the display accompanied by

a low beep.

PRIORITY CHANNEL

The Priority channel feature allows you to storeone of the 40 channels in the TX3400 as apriority channel that can be instantly recalled atthe press of a key. This can be used to provideinstant access to your working channel or yourlocal repeater channel.

To store a Priority channel:

1. Select the required channel.

2. Press and hold the Channel Knob. Thechannel display will flash for a moment thena high beep will be heard as the selectedchannel is stored.

To recall a Priority channel:

Briefly press the Channel Knob. The TX3400will immediately switch to the Priority channelaccompanied by a high beep.

The TX3400 features two scan groups - OpenScan and Group Scan.

Open Scan allows any of the fitted channelsto be scanned for activity in an ascendingsequence (i.e. from the lowest channel tothe highest). Channels are scanned at a rateof 20 channels per second. If a busychannel is found, scanning will pause toallow the signal to be heard. Once thechannel has been clear for 5 seconds,scanning will resume automatically.

Group Scan also allows any of the fittedchannels to be scanned for activity in anascending sequence, but in addition, it alsoinserts your Priority channel into the scansequence. This means that your Prioritychannel will be monitored regularly whilescanning to ensure that no calls are missed.Any signals received on your Prioritychannel will have priority over any signalsreceived on the other channels.

Selecting a Scan Group.

The current scan group is shown on the displayas OS for Open Scan or GS for Group Scan.

To change the selected scan group:

Briefly press the OS/GS key.

A beep will be heard and the display willchange to reflect the scan group you haveselected.

Programming Scan Channels.

Your TX3400 is supplied with all 40 UHF CBchannels programmed into the Open Scanmemory. Any channels not required can be

removed as necessary. The Group Scanmemory is empty by default and you will needto add channels to it before use.

To add or remove channels from either scanmemory:

1. Check that the radio is not alreadyscanning. If it is, briefly press the SCAN keyto cancel the scan function.

2. Select the required scan group by pressingthe OS/GS key.

3. Select the required channel using the rotarychannel selector switch.

If M is displayed to the upper left of thechannel number, the selected channel ispresently in the scan memory. It can beremoved by holding the SCAN key in for afew seconds until a low beep is heard. M

will then disappear indicating the channel isno longer in memory.

If M is not visible to the upper left of thechannel number, then the selected channelis not in the memory. To add it, hold theSCAN key in for a few seconds until a highbeep is heard. M will now appear to theupper left of the channel number.

4. Repeat step 3 to add or remove other

channels in the scan memory.

To Start Scanning:

To scan in the selected scan mode, brieflypress the SCAN key. A high beep will be heard,SCAN will appear in the display and the radiowill begin scanning.

NOTE: If there are less than 2 channelsprogrammed in the scan memory in Open Scanor one channel in Group Scan when you pressthe SCAN key, a long low beep will be heardand the command will be ignored.

Scanning in the Open Scan Mode.

If a busy channel is found, scanning willpause on that channel to allow the signal tobe heard and will remain there for as long as

the channel remains busy. Once the channelhas been clear for 5 seconds, scanning willresume automatically.

If your radio pauses on a busy channel andyou don't wish to listen to that conversation,briefly press the CALL button on top of themicrophone. The radio will skip over thatchannel and resume scanning from the nextchannel in the sequence.

To talk while paused on a busy channel,simply press the Push-To-Talk (PTT) buttonon the microphone. The SCAN mode will beput on hold and the radio will stay on thatchannel. You can now converse on thatchannel in the usual way. When you havefinished your conversation, briefly press theCALL button to resume scanning.

If your radio is paused on a busy channeland you wish to remain there, briefly press

the SCAN key. The radio will exit the Scanmode and remain on the busy channel.

If your radio is scanning and you need touse your Priority channel (for an urgent callor an emergency), briefly press the channelknob. The Scan mode will be cancelled andthe radio will jump straight to the Prioritychannel.

NOTE: Your TX3400 will not allow you to

transmit while it is scanning channels in theOpen Scan mode. If the PTT button is pressed

while scanning, the radio will give a low beepand will ignore the command. Your radio willonly transmit in the Open Scan mode while it ispaused on a busy channel.

Ending the Open Scan.

To stop scanning, briefly press the SCAN keyagain. A low beep will be heard and SCANwill disappear from the display. As long as theradio was not on a busy channel, it will returnto the last channel you selected, otherwise itwill stay on the busy channel.

Group Scan Mode.

With Group Scan selected, you can transmitand receive normally on your priority (working)

channel, but between breaks in theconversation, the radio will scan and listen toseveral other channels. The receiver willcontinue to scan the other channels ONLYWHILE THERE ARE NO SIGNALS ON THEPRIORITY CHANNEL.

If a signal appears on the priority channel it willoverride any signals being received on any ofthe other channels. In addition, if you press thePush-To-Talk switch on the microphone at any

time, the radio will transmit on the prioritychannel in the usual way.

Setting up your Group Scan.

To setup your radio for Group Scan:

1. Select the Group Scan mode by pressingthe OS/GS key so that GS is displayed.

2. Program your Prioritychannel memory with

your preferred working channel.

(a) Select the required channel.

(b) Press and hold the Channel knob for acouple of seconds. The channel display willflash for a moment then a high beep will beheard as the selected channel is stored.

3. Program the required other channels intoyour Group Scan memory.

(a) Select the required channel.

(b) If M is displayed to the upper left of thechannel number, the selected channel ispresently in the scan memory. It can beremoved by holding the SCAN key in for afew seconds until a low beep is heard. Mwill then disappear indicating the channel isno longer in memory.

(c) If M is not visible to the upper left of thechannel number, then the selected channelis not in the memory. To add it, hold theSCAN key in for a few seconds until a highbeep is heard. M will now appear to theupper left of the channel number.

(d) Repeat steps (a) to (c) to add or removeother channels in the scan memory.

To Start Scanning.

To scan in the Group Scan mode, briefly pressthe SCAN key. A high beep will be heard,SCAN will appear in the display and the radiowill begin scanning.

NOTE: If there are no channels programmed inthe Group Scan memory when you press theSCAN key, a low beep will be heard and thecommand will be ignored.

Scanning in the Group Scan Mode.

When scanning, the Group Scan feature scansall the channels programmed into the scanmemory, with the priority channel beingscanned after every fourth channel.

If a signal is heard on a scan channel, thereceiver will "lock" onto it and remain therefor as long as the channel is busy, and for 5

seconds after the channel has cleared, aslong as there are no signals on the prioritychannel. During this time the receiver willcontinue to check the priority channel forsignals every 2 seconds, resulting in a seriesof small 'breaks' in the reception of the'locked' channel. If no signals are heardafter 5 seconds, the radio wil l resumescanning.

If a signal appears on the priority channel at

any time (even when locked on a scanchannel) the receiver will switch straight to

the priority channel and will stay there for aslong as the channel is busy. During this timeyou can transmit on the priority channel inthe usual way. Once there has been noactivi ty on the pr ior i ty channel for 5seconds, the radio will resume scanning theother channels.

To talk on the priority (working) channelwhile scanning, simply press the Push-To-Talk switch on the microphone. The radiowill switch straight to the Priority channel.When you have finished your conversationand there has been no further activity on thepriority channel for 5 seconds, the radio willresume scanning the other channels.

If your radio pauses on a busy channel and

you don't wish to listen to that conversation,briefly press the CALL button on top of themicrophone. The radio will skip over thatchannel and resume scanning from the nextchannel in the sequence.

If your radio is paused on a busy channeland you wish to remain there, briefly pressthe SCAN key. The radio will exit the Scanmode and remain on the busy channel. Notethat the radio will no longer be monitoringthe Priority channel (unless it is the busychannel). To resume scanning, press the

SCAN key again.

To go directly to the Priority channel, brieflypress the Channel knob. The radio will exitthe Scan function.

Ending the Group Scan.

To cancel the Scan mode, briefly press theSCAN key. A low beep will be heard andSCAN will disappear from the display. If the

radio was on a busy channel it will remain onthat channel, otherwise it will return to thepriority channel.

GENERAL OVERVIEW

What is Selcall.

Your TX3400 has a Selective Calling (Selcall)system which operates like your telephone.Your radio has been programmed with its ownunique number. When this number is called,your TX3400 will beep to alert you.

If you do not want to hear any other activitywhile on the channel, you can push a QUIETbutton. The radio will then remain quiet untilyour number is called.

Your radio allows you to store up to four of yourmost frequently called numbers in memory.Each number can be labelled with a 5 lettername for easy identification.

Selcall Identification Number (Ident).

Your TX3400 is factory programmed with itsown unique Selcall Identif ication Number(Ident). This number identifies your radio from

others in your area. You will need to make yourIdent known to anyone who may need to callyou with Selcall. Whenever your TX3400 hearsa Selcall signal, it compares the incoming Identwith its own. If the two Idents match, the radioknows it is being called and sounds an alarm toalert you to the call.

The Selcall Ident for your radio is printed on thelabel on the rear panel of the main unit. TheIdent is the last 5 digits of the radios serialnumber.

The Selcall Ident is also displayed in thebottom left of the LCD for a second each timethe radio is turned on.

NOTE: Although your radios Selcall Ident ispre-programmed at the factory, you canarrange to have your dealer change it i f required.

Naming your Selcall Idents.

The TX3400 allows you to name up to four ofyour most often used Selcall Idents using a 5character word. The name can then be storedin memory with the Ident. This makes it easierto identify whos Ident you are recalling from

the memory. In addition, if an incoming Selcallmatches one of the Idents stored in thememory, its name can be displayed to make iteasier for you to identify the caller.

The QUIET Mode (Q)

Your TX3400 can be set to listen on a busychannel but not allow any sound to reach thespeaker UNLESS it receives its own SelcallIdent. In this way, your radio can monitor a

busy channel without disturbing you, but stilllet you know when you are being called.

The QUIET mode overr ides the normalSquelch system to ensure that the radioremains quiet even when the channel isbusy or the Squelch is opened with theSquelch key. When QUIET is set, you maysee BUSY appear on the display andsignal strengths appear on the S meterindicating the channel is being used.

However, unless someone transmits yourSelcall Ident, nothing will be heard in thespeaker.

The QUIET mode can be set to work onspecific channels i.e. some channels can beset to remain Quiet while others can remainOpen to all incoming signals.

If a signal containing your Selcall Ident isreceived, the QUIET mode is deactivated and

an alarm sounds to alert you to the call. Youcan then converse normally on the channel.

NOTE: Setting the QUIET mode is notmandatory. You can still use Selcall on anychannel whether the QUIET mode is set or not.

SENDING SELCALLS

Use the following procedure to enter and sendSelcalls.

To enter a Selcall IDENT.

Briefly press the CALL button on top of themicrophone. CALL TO will appear on thedisplay along with the last Selcall Ident yousent.

You can now either send the Ident that ispresently displayed or enter a new SelcallIdent. I f you do nothing, the radio wi l lautomatically exit the CALL TO mode after 20seconds and return to normal operation.

To enter a new Selcall Ident:

The righthand digit of the Selcall Ident will beflashing. This flashing digit indicates the digit tobe changed

1. Rotate the Channel knob to select therequired number in the flashing digitposition.

2. Briefly press the Channel knob to select thenext digit to program. A high beep will beheard and the next digit will flash.

3. Repeat steps 1 and 2 to program all 5 digitsas required.

Once the Ident has been entered you have 20seconds to send it otherwise the CALL TOmode will be cancelled and the Ident youentered will be lost.

To Send the Selcall Ident.

With the required Selcall Ident displayed in theCALL TO mode, press and hold the CALLbutton for a few seconds until the radio beeps.

The Selcall Ident will be sent automatically andthe radio will return to normal operation.

Call Acknowledge.

If your Selcall transmission is successful, theradio you called should respond with a callacknowledge signal - usually two quick beeps.This will confirm to you that the radio youcalled is now alerting its user to your signal.

STORING SELCALL IDENTS

Your TX3400 is fitted with four Selcall Identmemories, allowing you to store up to fourfrequently used Selcall Idents. The memoriesare accessed using the four keys beneath thedisplay labelled 1, 2, 3 and P.

NOTE: ThePkey is normally used to store thePAGE Ident for when the radio is used in thePAGE mode, but it can be also be used as astandard Selcall Ident memory if the PAGEmode is not in use. (The PAGE mode operationis described later in this manual).

To Store a Selcall Ident in memory.

1. Press the CALL button to select the CALL

TO mode.

2. Enter the required Selcall ident as describedpreviously.

3. Now press and hold (for about 2 seconds)one of the four keys directly below thedisplay labelled 1, 2, 3 or P. The SelcallIdent will flash for a few seconds, then theradio will beep as the Ident is stored.

To Recall a Selcall Ident from memory.

1. Briefly press the CALL button to select theCALL TO mode.

2. Briefly press the appropriate memory key (1,2, 3 or P). The Selcall ident stored in thatmemory will be displayed.

3. Press and hold the CALL button to send theIdent.

NAMING YOUR SELCALL IDENTS

Your TX3400 allows you to enter a 5 charactername for each Selcall Ident you have stored inmemory. This makes it easier to rememberwhose Selcall Ident you are recall ing. Inaddition, if an incoming Selcall matches one ofthose in your radios memory, the name can bedisplayed instead of the Selcall Ident, making iteasier to identify the caller.

Switching between Ident Mode and NameMode.

The TX3400 can be toggled between thenormal Ident mode and the Namemode asfollows:


2. Press and hold the Volume knob until theradio beeps. The TX3400 wil l togglebetween the Ident mode and the Namemode.

3. Briefly press the CALL button again toreturn to normal operation. The radio willremain in the selected mode.

Entering and Storing a Selcall Name.

NOTE: Before adding a Name to a Selcall Ident,you should first store the required Ident inmemory as described above. The stepsdescribed below assume that your TX3400 is inthe normal Ident mode.


2. Briefly press a memory key (1, 2, 3 or P). Ifthe radio is in Ident mode, the Selcall Identstored in that memory will be recalled anddisplayed.

3. Press and hold the Volume knob until abeep is heard. The radio will switch to theName mode and the displayed Identnumber will be replaced with characters.

4. Using the same procedure as used forentering Idents, rotate the Channel knob toselect the required letter in the flashingcharacter position, then press the knob tomove to the next character position.

5. When all characters have been entered,press and hold the memory key associatedwith that Ident to store the Name. The radiowill beep and the Name will be stored.

Repeat the procedure to add Names to anyother Selcall Idents stored in memory.


11/25

11

To exit the CALL TO mode, briefly press theCALL button. The radio will return to normaloperation.

The radio can now be left in the Name mode sothat an incoming Selcall matching one of thosein the radios memory will display the name

associated with that Selcall Ident instead of theIdent itself. Any Selcalls not matching those inthe memory will display the normal Ident in theusual way.

The way in which your TX3400 handles anincoming Selcall may vary depending on how ithas been programmed. The following sectiondescribes receiving Selcalls on the TX3400when using the standard factory defaultsettings.

RECEIVING SELCALLS

When your TX3400 receives its own Selcallnumber, it will beep to alert you to the call. Inaddition, it will cancel the QUIET mode (ifselected) and display the Ident or Name of thecaller.

Displaying the Callers Ident or Name.

Whenever your TX3400 receives its ownSelcall Ident, the words CALL FROM willappear on your display above the callersSelcall Ident or Name to inform you of theidentity of the person calling.

The Selcall Alarm.

When your TX3400 receives its Selcall Ident, analarm will sound in the speaker to alert you tothe call. Initially the alarm will beep urgently at

2 beeps per second for around 10 secondsthen slow to around 1 beep every 3 seconds ifthe call is not answered. It will then continue tobeep indefinitely until you cancel it.

Cancelling the Selcall Alarm.

Pressing just about any key or knob on theTX3400 will cancel the Selcall Alarm. However,the following are the recommended methods.

If you want to Cancel the Alarm and listen

on the channel:

Briefly press the Volume/Quiet knob. Thealarm will stop beeping and the channel willremain open to any incoming signals.

If you want to Cancel the Alarm and talk onthe channel:

Press the PTT switch on the microphoneand talk in the usual way. The alarm will be

cancelled and the channel will be open fornormal communication.

If you want to Recall the Callers Ident andreturn the call:

Briefly press the CALL button on themicrophone. The radio will enter the CALLTO mode and will insert the callers Ident orName ready for sending. Now simply pressand hold the CALL button for a few

seconds until the radio beeps. The Selcallwill be sent to the caller.

Call Acknowledge Signal.

When your TX3400 receives its own SelcallIdent, it automatically responds by transmittingan acknowledge signal back to the caller.This informs the caller that their Selcalltransmission has been successful and thatyour radio is alerting you to their call. The

acknowledge signal is heard at the callers endas two quick beeps.

USING THE QUIET MODE

The QUIET mode prevents any inc omingtransmissions from being heard in yourTX3400s speaker until your Selcall Ident is

received. This allows you to monitor a busychannel for calls without being disturbed byunwanted signals.

When your Selcall Ident is received, the QUIETmode is cancelled and all incoming signals willbe heard in the speaker.

The QUIET mode is setup by first tagging thechannels that you want to stay Quiet, thenactivating the QUIET mode. Once QUIET is

activated, the channels you have tagged willremain Quiet to all incoming signals. Channelsnot tagged will operate normally.

To Tag individual channels for QUIEToperation.

1. Select the required channel by rotating theChannel knob.

2. Press and hold the Volume/Quiet knob until

a high beep is heard. Q will appear to theupper left of the channel number indicatingthis channel is now tagged for Quietoperation.

Repeat steps 1 and 2 to tag all requiredchannels.

To Activate the QUIET Mode.

1. Select any channel that has been tagged for

Quiet operation. Q will be displayed.

2. Br ief ly press the Volume/Quiet knob.QUIET will appear on the right of thedisplay.

Now all channels tagged for Quiet operationwill be operating in the Quiet Mode.

(You can test this by opening the squelch usingthe squelch key and selecting various channels

with the Channel knob. The radios backgroundnoise will be heard on normal open channels

but will remain quiet on those channels that areset for Quiet operation.)

NOTE: You cannot activate the Quiet modeunless you have selected a tagged channelwith Q displayed.

To De-activate the QUIET Mode.

1. Select any channel that has been tagged forQuiet operation. Q and QUIET will bedisplayed.

2. Now briefly press the Volume/Quiet knob.

QUIET will disappear on the right of thedisplay and all channels tagged for Quietoperation will now operate normally again.

To Remove the QUIET Tagging.

1. Select a channel that has been tagged forQuiet operation. Q will be displayed to theupper left of the channel number.

2. Now press and hold the Volume/Quiet

knob until a low beep is heard. Q wil ldisappear indicating this channel is nolonger tagged for Quiet operation.

Receiving Signals in the QUIET Mode.

If a normal signal is received on a QUIETchannel, the channel will appear busy butno sound will be heard from the speaker.This means you will not be disturbed by thesignal.

If a normal signal is received on an Openchannel (one that is not tagged with Q) thesignal will be heard in the usual way.

GROUP CALLS

SCANNING IN THE QUIET MODE

The TX3400 will allow you to scan while theQUIET mode is active. You can then monitor agroup of Quiet channels or a combination ofQuiet and Open channels.

To Scan in the QUIET Mode:

1. Press the OS/GS key to select the requiredScan group.

2. Select the channels you wish to remainQuiet and tag each one with Q.

3. With a tagged channel selected, brieflypress the Volume/Quiet knob to activatethe QUIET Mode.

4. Now press the SCAN key. The radio willbegin scanning and SCAN wi l l bedisplayed.

If a normal signal is received on an openchannel, scanning will pause while thechannel is busy and will resume scanning 5seconds after the channel becomes clear. (Ifyou were scanning in GS mode, the radio

may switch between the open channel andthe Priority channel. This is normal).

If a normal signal is received on a Quietchannel but your Selcall Ident is notdetected, the signal will be ignored andscanning will continue.

If a signal containing your Selcall Ident isreceived on any channel - Open or Quiet -both scanning and QUIET modes will becancelled and the receiver will stay on thatchannel. In addition, the alarm will beep toalert you to the call and the callers Ident willbe displayed. The channel will now be openfor normal transmission and reception.

NOTE: To ensure reliable Selcall detection

when scanning, it is recommended that yourestrict the number of channels in the Scangroup.

In Open Scan Mode: 10 Channels

In Group Scan Mode:8 Channel plus thePriority Channel

The TX3400s Selcall system includes a GroupCall function which allows you to call up to 10radios simultaneously. This could be useful inan emergency situation where you may need totransmit a message to a number of radios inyour group.

The Group Call function works by allowing youto enter a special group code into the lastdigit posit ion of the Selcall Ident you aresending. The group code appears as an Awhen displayed in the radio. When this groupcode is received, it substitutes for any othernumber in the last digit position. As long as thefirst 4 digits of the Selcall you are sendingmatch those of the radios you are calling, theirSelcall alarms will be activated as if their full 5

digit Selcall Idents had been received.

To achieve this, the 10 radios you are calling

must be programmed with sequentiallynumbered Selcall Idents.

i.e. 12030, 12031, 12032, 10233 . . --> , 12039

e.g.

Transmitting the Selcall Ident 12031 will onlyactivate the alarm in the radio with theSelcall Ident of 12031.

Transmitting 1203A will activate the alarmsin all radios with Idents 12030 through12039 (a total of 10 radios).

If the radios in your f leet do not havesequentially numbered Selcall Idents and you

want to make use of this function, you canarrange for your dealer to re-program yourradios.

Programming and Sending Group Calls.

Entering a Group call Ident is the same asentering a normal Selcall Ident.

1. Briefly press the CALL button on top of themicrophone. CALL TO will appear on the

display along with the last Selcall Ident yousent.

The righthand digit of the Selcall Ident willbe flashing. This flashing digit indicates thedigit to be programmed.

2. Rotate the Channel knob to select A in therighthand flashing digit position. This isspecial code that will create the Group Call.

3. Briefly press the Channel knob to select thenext digit to program. A high beep will beheard and the next digit will flash.

4. Rotate the Channel knob to select therequired number in the next flashing digitposition.

5. Repeat steps 3 and 4 to program all 5 digitsas required. When completed, the first 4digits of the Ident you have entered will

match all the radios in the group. The lastdigit will be set to A.

Once the Ident has been entered you have 20seconds to send it otherwise the CALL TOmode will be cancelled and the Ident youentered will be lost.

To Send the Selcall Ident.

With the required Selcall Ident displayed in theCALL TO mode, press and hold the CALLbutton for a few seconds until the radio beeps.The Selcall Ident will be sent automatically andthe radio will return to normal operation.

Call Acknowledge in Group Mode.

There is no call acknowledge when sendinggroup calls. This is to prevent all the radios inyour group from trying to respond to yourSelcall transmission at the same time.

Storing group Call Idents.

Group Call Idents can be stored in memory inthe same was as a standard Selcall Ident.

Simply follow the instructions for storing SelcallIdents in memory as described earlier in thismanual.

Receiving Group Calls.

Receiving a Group call is identical to receivinga normal Selcall except that the alarm sound is

a LOW tone beep instead of the normal Hightone beep. The Callers Ident or Name appearson the display in the usual way.

The PAGE or transpond feature allows you toleave your radio unattended yet sti l l beinformed of any incoming Selcalls. If yourSelcall Ident is received while your TX3400 is inthe PAGE mode, it will automatically callanother UHF radio to alert you to the call.

To receive the Paging call, the other UHF radiomust be fitted with a CCIR compatible Selcall(such as a TX3400, TX4200, TX4000, TX6000

or TX475S.

NOTE: To allow your TX3400 to operate in the

PAGE mode when your vehicle is unattended,your radio must be wired so that it has acontinuous 13.8 volt power source even whenthe vehicles ignit ion is switched off (seeinstallation instructions).

Selecting the Paging Channel.

Your TX3400s Paging channel is factory set toUHF CB channel 23. If channel 23 is not

suitable for use in your area, you can arrangefor your dealer to reprogram it to another of the40 UHF CB channels.

CTCSS (Continuous Tone Coded SquelchSystem) is a quieting system that allows agroup of radios to talk to each other withouthearing other users on the channel. The systemapplies a continuous low level tone to yourtransmission, and a matching tone decoder toyour receiver's squelch. When CTCSS isenabled the channel remains quiet unti lsomeone transmits using the same tone. Whenthe transmission ends, the channel becomesquiet again. By using different tones, severalgroups of people can share the same channelwithout disturbing each other.

Your TX3400 is CTCSS ready. This means thatCTCSS is designed into your TX3400, butdisabled at the factory. The AustralianCommunications Authority does not yet permitthe use of CTCSS on CB frequencies. However,when approval for CTCSS is granted, you maycontact your dealer to arrange for this featureto be enabled.

The following description assumes CTCSS hasbeen enabled by your dealer.

The TX3400 allows CTCSS to be enabled ordisabled on individual channels. In addition, the

CTCSS

DC POWER CONNECTION

The TX3400 is designed for 13.8 Volt DC,negative earth installations only (i.e. where thenegative terminal of the battery is connected tothe chassis or frame of the vehicle).

There are two recommended methods ofinstallation.

Radio remains on when the ignition switchis off:

Connect the radio's negative (black) lead to thevehicle's chassis, or if preferred, directly to thebattery's negative terminal.

The radio's positive (red) lead should beconnected directly to the battery's positiveterminal. Alternatively, the positive lead could

be connected into the fuse box at a point thathas +13.8 Volts continuously available(preferably the battery side of the ignitionswitch).

Radio turns off with the ignition switch:

Connect the radio's negative (black) lead to thevehicle's chassis, or if preferred, directly to thebattery's negative terminal.

The radio's positive (red) lead should connectto an accessory point in the vehicle's fuse box.This point should supply +13.8 Volts only whenthe ignition switch is turned ON or in theACCESSORY position.

HIGH VOLTAGE WARNING

The TX3400 has a built- in, high voltagedetection system to warn you if an overvoltagesituation occurs.

If the power supply voltage exceeds 18 Volts

21/25

DC, the channel display will flash hi dc for 5seconds when the unit is first turned on, or atthe time the voltage exceeds 18 Volts. Inaddition, when transmitting, the TX indicatorwill flash and the transmitter will select lowoutput power.

If the overvoltage warning appears you shouldswitch your TX3400 off and disconnect it fromthe power source, before locating the cause ofthe trouble.

Once the High Voltage warning has beentriggered, and you have fixed the source of theproblem, you will need to switch the TX3400OFF then ON again to reset it.

If the power source exceeds 30 Volts, theinternal protection diode will cause the fuse toblow.

ANTENNA CONNECTION

GME Electrophone supply a wide range of

mobile and base station antennas designedspecifically for UHF CB communications.

The antennas are fitted with a PL259 coaxialplug suitable for connection to the antennasocket on the rear panel of the transceiver.

A repeater system consists of a l inkedtransmitter/receiver combination installed in aprominent location. The repeater is designed toreceive signals on a designated channel andre-transmit them on another channel.

Repeaters are usually located on hil ls,mountains or tall buildings. The increasedelevation greatly improves the range of the

repeater beyond that of a normal base ormobile. This means that the repeaters are ableto receive and retransmit signals to radios thatwould otherwise be out of range of each other.

Normally, UHF transceivers transmit and

receive on the same channel. This is known asSIMPLEX operation. However, to communicatethrough repeaters, your transceiver must be
