2 MANDATORY REGISTRATION

You must register your EPIRB with the appropriate authorities.Failure to register may slow the rescue and lead to loss of life.In the USA failure to register may result in a fine.In the UK you are legally required to register your EPIRB.

2.1 OverviewEvery EPIRB is pre-programmed with a unique identity before it reaches the customer.This is done by the manufacturer or in some cases the distributor. The identity includesa 3 digit country code. This is the country that takes responsibility for storing thatparticular EPIRB's registration details. In most cases this is the country to which thevessel is flagged. The country programmed into your EPIRB can be found from its rearidentity label. You must register with this country.

Country

When you activate your EPIRB in an emergency, the nearest maritime search andrescue coordination centre (MRCC) will receive the message and decode the countrycode (eg 232). They will then access the registration database for that country andexpect to find details of your vessel, its radio equipment and who to contact. If they failto find this information, thismay slow down any rescue.

2.2 How to registerThree registration forms are provided, two are for future use and one must becompleted immediately. The forms are all pre-printed with your EPIRB's identity, allyou have to do is complete details of your vessel and provide contact numbers.Wherever possible the forms are also pre-printed with the correct mailing address anda faxback number. If your form does not have a mailing address, contact your supplier.When you have completed the form, you can choose to fax it or mail it.

It is usual to receive confirmation when you register. In the UK and USA you will alsoreceive a "Decal" sticker which you must fit to the EPIRB itself. The Decal is proof ofregistration. Not having a Decal is an offence.

2.5 Sale or transferEPIRBs registered in the USA, Canada, UK and Australia do not need to be re-programmed when transferred to a new vessel. Simply complete another registrationform to inform the authorities of the transfer. Use one of the spare forms provided orcontact McMurdo for a blank form. (See warranty section for address).For most other countries, the EPIRB must be re-programmed with either the newvessel's Maritime Mobile Station Identity (MMSI) or its radio callsign, whichever isrequired by the country controlling the new vessel.

Since the EPIRB identity contains a country code, it follows that changing the flag stateof the vessel also means the EPIRB must be re-programmed. Programming can becarried out at McMurdo or any of our designated agents. For details of your nearestagent, either contact McMurdo using the details in the warranty section, or visit theMcMurdo web site at www.mcmurdo.co.uk.

This is a flexible whip. It must be near vertical whenoperating.If the antenna gets bent, gently straighten it out.This is the glass U-tube visible through the clear lens dome.When the EPIRB is activated this will flash every fewseconds.Visible through the clear lens dome at the rear of theEPIRB.This stays on or flashes to show which mode the EPIRB isin.A dimple in the clear dome, through which your supplier canoptically input the coded message unique to your EPIRB.You must register the coded message with localauthorities.Press this key once to de-activate the EPIRB. Hold it downto run the built-in self-test. which checks basic operation.Press this key to activate the EPIRB manually. The key isprotected by a sliding door which is fitted with a securityseal.The two screw heads below the keys are sea switchcontacts. Submerge these in water to automatically activatethe EPIRB.Pull the lanyard spool down to free it. Use the cord to tetherthe EPIRB to a survival craft.Never tie the EPIRB to your vessel.

4 CONTROLS4.1 ON buttonThis is hidden behind a sliding cover which protects it from accidental activation. Thecover has a security seal to show if the EPIRB has been activated.

The EPIRB can be activated manually by sliding the cover to the left (breaking theseal) and then momentarily pressing the ON button.When activated the EPIRB strobe will start to flash immediately. It will not make anydistress transmissions for 2 minutes. This gives you a chance to turn it off ifyouactivated it accidentally. During this 2 minutes the red lamp illuminates continuously.When the red lamp starts to flash, the 2 minutes delay has passed and distresstransmissions have started.

4.2 READY buttonThis button de-activates the EPIRB and also tests the EPIRB.

Self-test

Pressing and releasing this button quickly will de-activate the EPIRBand return it to its "ready" state. When the button is released thestrobe and the red & green lamps will stop flashing.Pressing and holding the ready button (for about 10 seconds) willallow the built-in self-test to run. Full details of the self-test are givenin section 10.1

4.3 Sea switchIt is important to realise that the only time the EPIRB is completely off is when it isfitted in its mounting bracketor enclosure. As soon as you take itout, a magneticswitch activates and puts the EPIRB into its "ready" state. It will not drain the battery inthis state, but it will turnon automatically if the sea switch contacts are immersed inwater. The sea contacts are the two exposed screwheads besidethe rear switches.

Although you can control the EPIRB manually with the READY and ON switches, thesea switch overrides any manual settings. For the manual switches to operate propertythe EPIRB must first be dry so that the sea switch is de-activated.

To ensure the sea switch operates property in rough seas, it has a built-in time delay. Ithas to be wet for at least 2 seconds before it will activate and it has to be dry for atleast 8 seconds before it will de-activate.

4.4 Lamps

4.4.1 StrobeThe strobe is the visual means of locating the EPIRB. When activated, the strobeflashes 23 times per minute, with a pause during the time when the EPIRB istransmitting.

The strobe is also used to indicate the result of a self test (see section 10.1).

4.4.2 Red lampThe red lamp is used to indicate transmissions by the EPIRB. When activated, itflashes alternately with the strobe to indicate a good transmission on 121.5 MHz. Every50 seconds it illuminates for 2 seconds to indicate a good transmission on 406 MHz.

When the EPIRB is first activated the red lamp is illuminated continuously until theEPiRB begins to transmit, when it begins to flash.

The red lamp is also used to indicate the result of a self test (see section 10.1).

5 OPERAliNG PROCEDUREAn EPIRB is a piece of life saving equipment. Its sole purpose is to call for help.It must only be used in situations of grave and imminent danger.Misuse can involve a severe penalty.

5.1 SinkingIf you have a category 1 "float-free" enclosure (see marking on enclosure label), then ifyour vessel sinks, the EPIRB will automatically release itself from its enclosure beforeit reaches a depth of 4 metres. The EPIRB will float to the surface and start to operatebecause its sea switch is activated.

If possible, the EPIRB should berecovered and tied (using its lanyard) tothe survival craft. An EPIRB is meant tomark survivors, not the accident scene.

For best operation leave the EPIRBfloating in the sea near the survival craft,as this is the condition for which it wasdesigned and tested.

NOTE: Satellite coverage at the time an alert is transmitted and, if activated onboard aship or raft, overhead obstruction on the ship or raft, may affect whether and how soonan alert is received by the satellite system.

5.2 Abandon shipIf the vessel is sinking and there is time to fetch the EPIRB then this should always bedone. Release the EPiRB from its mounting bracket as described in section 5.3 or 5.4and carry it to one of the Iiferafts. Once the liferaft is in the water, uncoil the lanyardand tie it to the Iiferaft, then throw the EPIRB overboard so that it floats next to theIiferaft. The EPIRB will operate because its sea switch will activate,

10

Getting the best from your EPIRBYour EPIRB is designed and optim ised to be used floating in the sea. However, if youhave to use it in other situations, this section provides guidance on how to get the bestfrom any EPIRB. (The beacon shown is to illustrate the principles of operation.)

Aboard ship:

DO: Place the EPIRB in the open ,

clear of overhangs

Keep the EPIRB upright (hold ltif necessary)

Switch on the EPIRB

DON'T: Place the EPIRB close to large

structures

Lay the ERIRB on its side

Place the EPIRB under cove r

In a Iiferaft:

DO: Make sure you switch on the EPIRB

Hold the EPIRB up as high as possible.

Note : the high intensity flashing strobe light may cause discomfort if viewed forprolonged periods.

We recommend that the EPIRB is used floating in the sea

o~~EPIRB~ /will flash

Once activated the EPIRB must have its antenna as upright as possible and it musthave a clear view of the sky for proper operation. Laying it on its side or placing it nextto a metal wall will impair its range and may fail to alert the rescue services. Avoidhandling the antenna, as this will also impair performance.

5.6 DeactivationIf your EPIRB has been activated for a cumulative period in excess of 2 hours then itsbattery will need replacing. This is necessary to ensure that in an emergency it willoperate for the full 48 hours required by government regulations. See section 10.3 forbattery replacement instructions.

If the EPIRB was activated by mistake or if the emergency ends then the EPIRB canbe reset back to its "ready" state as follows: Remove EPIRB from any water and dry its sea switch contacts Wait 8 seconds for sea switch to turn off

If EPIRB is still flashing then it must havebeen tumed on manually: Slide the switch cover fully to the

right. Press and release READY button.

If EPIRB is still flashing then it has a fault.Refer to section 6 on False Alarms.

9.4 Marking Hydrostatic Release Unit (HRU) expiryIf you are installing a float-free EPIRB you must now mark the HRU expiry date. TheHRU has a 2 year in-service life which starts as soon as it gets exposure to a marineenvironment. Hence the 2 years starts at installation and it is left to the customer tomark this date during installation. A date 2 years into the future should be marked onthe HRU body and copied onto the label on the side of the enclosure. The HRU ismarked by CUlling out the corresponding dates on its label, as shown on the separateleaflet.

The enclosure should be marked using the alpha-numeric stickers provided, thencovering them with the clear adhesive label provided (but see 9.5 first). The preferreddate format is month and year, for example: JUN 2003.

24

6.3 Dealing with a transmitting EPIRBIn the unlikely event that your EPIRB develops a fault and will not turn off, then preventits radio signal from reaching the satellite using one of the following methods:

Remove the antenna, Wrap the EPIRB in metal foil and take it belowdecks.

or Remove the antenna and place the EPIRB in a metal container or locker.

Take care when removing the antenna. Handle the antenna as little as possible.Refer to Section 1 for warnings.

Leave the EPIRB in this condition for 3 days until its battery is dead, then refer tosection lOA for instructions on returning the EPIRB for servicing. See also section 7.

19

7 FULLY DISABLING AN EPIRBIn the unlikely event that your EPIRB refuses to turn off then it may have a fault.Procedures for dealing with a faulty EPIRB are covered in section 6 on false alarms; insimple terms you should do the following:

De-activate the EPIRB as described in section 6.2 Suppress its signal by removing the antenna and wrapping the EPIRB in

metal foil, as described in section 6.3 Leave for 3 days until the battery is used up.

We do not recommend any other course of action.

However, if it is absolutely necessary to fully disable an EPIRB (by unplugging itsbattery), proceed as follows:

This is a dangerous task and should only be performed by a qualified technician.WARNING: Risk of electric shock. Proceed at your own risk, no liability accepted.Especially dangerous for those with pacemakers or heart conditions.

Take the EPIRB below decks into a dry area. Locate a flat bladed screwdriver with a long reach, and a

cross-headed screwdriver. Using the flat-bladed screwdriver, unscrew and retain the

front 4 sealing screws. Pull the lanyard out and remove the 2.hidden rear screws. 270 V DC Do not as yet remove the sea contact screws. Lift the lens dome off. Remove and retain the blue gasket. Avoid touching the circuit board and the glass strobe tube. Hold the hexagon shaped pillars and remove the sea screws. Use the cross-headed screwdriver to remove the front screw. Grip the white plastic coil former and lift the circuit board up 3cm (1"). Using fingers, unplug the white 4-way battery connector. The flashing will now cease. Collect all the parts and return them to your nearest service agent.

20

8 WALL BRACKET INSTALLATION8.1 SitingThe wall bracket should ideally be sited in plain view near an emergency exit. Whenchoosing a suitable mounting position you should also consider:

Ease of access in an emergency. Mount at least 1 metre (3') from any compass equipment. Allow at least 25mm (1") above the bracket for it to spring open. Allow 18cm (7") for the antenna. Heavy bending of the antenna is bad. If there is any likelihood of the EPiRB being replaced in its bracket after

activation then ensure that the antenna has as clear a view of the sky aspossible.

8.2 Mounting procedureThe wall bracket is supplied with a set of stainless steel fixings 25mm (1") in length.The bracket mounts against a flat surface using 4 fixing points. Offer the bracket intothe chosen position and mark through the mounting slots. If you are using the nuts andbolts supplied, drill6mm (114") holes in the centre of each mark. You will need a 4mmAlien key to tighten the bolts. If the rear of the mounting surface is inaccessible thenuse the self-tapping screws supplied and drill 3mm (1/8") holes. Always fit washersunder the heads of the screws to avoid damage to the plastic.

8.2.1 Mounting instruction plateThe EPIRB is supplied with an instruction plate. This is a rigid plate with basic visualinstructions for how to operate the EPIRB in an emergency. The plate varies slightlydepending on whether you have a wall bracket or a full enclosure. The wall bracketversion is illustrated below.

9 ENCLOSURE INSTALLATION9.1 SitingThe enclosure should be mounted upright against a vertical bulkhead. Alternately, itmay be mounted horizontally on a flat surface, such as a cabin roof. No otherorientations are recommended.

If you have a float-free EPIRB it is critical that you choose a position where thereleased EPIRB will not get trapped by overhangs, rigging, antennas etc, shouldthe vessel ever sink. An expanse of flat surface is required to allow the enclosure lidto eject. Use the list below to choose a suitable mounting position:

Mount on the outside of the vessel's structure, as high as possible. Mount closeto the vessel'snavigation position. Consider ease of access in an emergency.

AVOID: Positions with insufficient space for lid ejection and maintenance. Positions within 1m (3') of any compass equipment. Mounting within 2m (6') of any Radar antenna. Direct impact from waves Siting where damage is likely. Exhaust fumes, chemical and oil sources.

9.2 Mounting procedureThe enclosure mounts against a flat surface using 4 fixing points. See illustration formounting dimensions, or use the backplate of the enclosure as a marking guide. To dothis, pull out the R-shaped clip and remove the enclosure lid. Note how the EPIRB fitsthen remove it to somewhere dry (its sea switch is now armed).Offer the back plate into the chosen position and mark through the mounting holes.The enclosure is supplied with a set of 25mm (1") stainless steel fixings. If you areusing the nuts and bolts, drill6mm (1/4") holes where you have marked. You will needa 4mm Alien key to tighten the bolts. If the rear of the mounting surface is inaccessible,use the self-tapping screws supplied. Always fit washers under heads of the screws toavoid damaging the plastic.

The HRU ismarked by cutting out the corresponding dates on its label, as shown on the separateleaflet.

The enclosure should be marked using the alpha-numeric stickers provided, thencovering them with the clear adhesive label provided (but see 9.5 first). The preferreddate format is month and year, for example: JUN 2003.

24

9.5 Marking vessel nameIn many countries it is usual to have your EPIRB programmed by your supplier (seeregistration section). Your supplier will then mark all the EPIRB labels accordingly.However, if your EPIRB was purchased in the USA, Canada or UK then your EPIRBwill have all the necessary markings except for vessel name. In these countries it isusually left to the customer to mark the vessel name during installation.

It is strongly recommended (and is mandatory in some countries) that the vessel nameis marked on the rear of the EPIRB itself and also on the enclosure, if you have one.Use the alpha-numeric stickers provided to mark the vessel name (or its abbreviation)on the top line of the EPIRB's rear label and again on the enclosure label. Protect themarkings with a section of the clear adhesive label provided.

1. Pick off required letter (a smallknife blade works well)

2. Apply letter to labelRepeat until name is complete

3. Cover letters with clear label

25

10.3 Battery replacementThe EPIRB uses a 9V Lithium battery pack, McMucdo type 82-140. Typically this willhave to be replaced every 5 years. The exact battery expiry date is marked on the rearof the EPIRB lens dome and if you have a full enclosure it is also marked on theoutside of the enclosure. The battery expiry date should be checked regUlarly. You willneed to replace the battery when:

The expiry date has been reached or The EPIRB has been used in an emergency situation or A false activation exceeds 2 hours of use.

The battery is a one shot device. It is not rechargeable or user replaceable. Batteryreplacement must be carried out by a McMurdo approved service agent. Lithiumbatteries have special disposal requirements. Never incinerate a Lithium battery. Neverdispose of one at sea. Your service agent will deal with battery disposal.

10.4 ServicingAll servicing must be carried out by a McMurdo approved service agent. Always callyour nearest agent and talk to their service department before returning equipment.You can find your nearest service agent from:

The McMurdo web site: www.mcmurdo.co.uk Contacting McMurdo direct (see warranty page). Contacting a McMurdo distributor

If the EPIRB has to be returned, the original packa~ing should be used if possible.

10.5 TransportationBecause it contains a Lithium battery, the EPIRB may have special transportationrequirements depending on local and international regulations in force at the time.

The battery pack contains approx 6.5gm of Lithium (each battery pack contains 3 cellswith

11 HOW DOES IT WORK?Your EPIRB contains two radio transmitters: one operating at 406 MHz which transmitsan alert which can be received by satellites, and one operating at 121,5 MHz whichtransmits a signal which can be rece ved by overflying aircraft and Search & Rescue(SAR) homing receivers, When you activate the EPIRB, both transmitters startbroadcasting signals. Providing the EPIRB's batteries are in good condition, thetransmission will continue for a minimum of 48 hours.

The 406 MHz alert signal can be detected by SAR satellites. American, European andIndian authorities operate a series of satellites in low-earth and geostationary orbits todetect and locate aviators. mariners and land-based users in distress. The satellites,together with a world-wide network of ground stations and Mission Control Centres(MCC) form the International ~OSP".S-SARSATProgram whose mission is to relaydistress signals to the international search and rescue community.

Ground stations track these satellites and process the distress signals to obtain alocation (by using Doppler location techniques') of the distress. The processedinformation is then forwarded to an MCC where it is combined with other location andregistration information and passed to a Rescue Coordination Centre (RCC) whichalerts the appropriate SAR authorities. Successive satellite passes refine and confirmthis information.

For an explanation, visit the webpege:http://www.cospassarsat.crglDescrlptionOverviewldoppler.htm

The network of orbiting sa:ellrtes can detect signals over the entire surface of the earth;in addition, there are four geostationary satellites that appear fixed in position andwhich detect signals over enormous areas (approximately one-third of the surface ofthe earth, but excluding Polar regions). However, the geostationary satellites, becausethey are fixed with resped to the earth, cannot determine the position of the EPIRBusing Doppler.

An EPIRB should not be switched off once activated for a distress situation until theSAR agency directs this.

14 APPENDIX - SATELLITE SYSTEMSCOSPAS-SARSAT satellite systemThe COSPASSARSAT system provides distress alert and location information tosearch and rescue authorities anywhere in the world for maritime, aviation andterrestrial users in distress.

There are two satelite arrays carrying the COSPASSARSAT system. The principalarray is LEOSAR (Low Earth Orbit Search and Rescu e) which has seven satellites inpolar and near-polar orbits. The orbits of these satellites are arranged to scan theentire surface of the Ear.h; 01 averace , a satellite comes into view every 45 minutes.

LEOSAR satellite path arrd scan footprin t

Distress transmissions tro-n EPIRBs are picked up by the satellites and retransmittedto ground receiving stations, which then pass the message to the appropriate rescueorganisation. On average , the total delay from activation of an EPIRB to the messagebeing received by the rescue services is 90 minute s.

COSPASSARSAT is in an advanced stage of commissioning the second satellitearray, GEOSAR (Geostationary Search and Rescue ). This array uses geostationarysatellites which are always in view (over their area of cove rage), so that reception ofthe EPIRB signal is virtual I' hstantaneous.
