4)

Remove the screws @.

Insert a fine-pointed screwdriver into the notches on either

side of the fixture @, pry open, then lift upward and remove

by pulling the legs on both sides @.

Move the gears in the direction indicated by the arrow @ to

release the pickup’s catch and cause the loading table” (here-

after referred to as the tray) to come out in direction @.

With the tray fully opened, remove the tray by lifting slightly

and pulling forward.

Push the slide @ completely in.

Align the hole in the loading cam gear @ with the hole in the

lower chassis.

Align the two projections inside the loading gear G with the

dividing rib of the loading cam gear @ as shown in the illus-

tration.

With the tray in this position, push in the tray so that the pro-

jections in the loading gear ~ align with the groove in the

window in the tray. At this time, align one of the projections in

the loading gear ~ with the teeth in the middle of the three

gears visible through the tray window. -

With the front portion of the tray tilted downward about 5 de-

grees, slowly push the tray into the mechanism.

Set the fixture in place and screw in the screws @.

2. Disassembly of the mechanism

(1) Removing the pickup block

1) Turn the gear (the above illustration @) in the direction indi-

cated by the arrow and completely lower the sub chassis,

then turn over the chassis. (The fixture does not need to be

removed.)

2) The sub chassis can be removed once the screw @ is re-

moved. Removing the screw and washer @ makes it possi-

ble to remove the base mechanism chassis.

pickup rail in the direction indicated by the arrows and

pushing out the rail.

After readjusting or replacing the pickup, be sure to wipe

the pickup rail and apply FLOIL grease (G-474B) to the en-

tire length and diameter. (This should be done each time

the pickup is replaced. Be sure that no grease is applied to

any other part.)

To attach the pickup rail, slide the pickup onto the pickup

rail and push until it hooks on the catches. At this time, ap-

ply a small amount of “CEMEDAIN” #575 to the area be-

tween the catches and the end of the shaft. (Apply after rail

attachment is completed.)

Next, apply FLOIL grease (G-474B) around the boss of the

threaded gear, then push in the threaded gear while push-

ing the pickup slightly inward.

. The circuitry of the PCB attached to the pickup has been

short-circuited as shown in the illustration to prevent dam-

age from static electricity.

After replacing the pickup, release this short-circuit in the

circuitry and change to the “open” state. r u(PEN

. Precautions when handling the pickup or CD mechanism

1. As the pickup and flexible lead line are easily damaged by static electricity, do not handle with bare hands.

2. Before shipping the CD mechanism, place in an antistatic bag, move the pickup to the innermost position, and set to the

chucking state (in which the turntable is up). Before shipping the pickup, short-circuit the circuitry on the PCB and attach

the lens cover in order to protect from static electricity.

(2) Description of tests after entering the service mode

In this mode, the spectrum analyzer functions as a counter display (00 + FF + 00 --”--). In this mode, REC only works

with FWD. (The REV key has no effect when pressed from ret/pause status.) In this mode, the AMSS function does not

operate. It is replaces by normal cue/review operation.

Insert a tape and press the RECORD key. The function switches to AUX, with recording bias on and rec mute off, and

the motor turns on. (The plunger does not function.)

Pressing the PLAY/PAUSE key from the above status causes the unit to switch to record status and resets the

counter. The reel pulse counter starts 0.5 seconds after the mechanism’s PLAY switch is turned on. The counter

value is displayed on the LCD.

Pressing the STOP key is the above status causes the function to switch tot tape.

Then, 0.5 seconds after the mechanism’s R/F switch is turned off, reel pulse counter stops.

Rewind starts immediately thereafter and the tape is would back the same number of reel pulses that have elapsed

since recording started. The status then changes from stop to play and the portion of the tape that was just recorded

is played. The counter display operates during the above.

If the tape was rewound too far, those reel pulses are counted negatively.

The unit remains in play status for the same number of reel pulses that elapsed during record status.

After the number of reel pulses that elapsed during record status have

Operations 7. and 8. are repeated until the STOP, FF or REW key is pressed:

Pressing the FF or REW key while the operations described above are taking place initiates the cue/review function,

after which the~e are,,no repetitions of the above operations.,,.Pressing the STOP key puts the units into stop status. after which there are no repetitions of the above operations.
