REMOVAL AND INSTALLATION
●Disconnect the AC adaptor’s plug.
●Remove the batteries.
●All wiring should be returned to the original position after work is completed.
●First have ready many the new FIXERS (614 129 4971) for replacement.

The pick-up rail has been installed,
first wipe the tips of the rail with alcohol.
After the pick-up has been replaced, apply
grease (FLOIL G-4746) to the rail.
The pick-up Flexible P.W. Board patiern is
“shorted”, as shown in the figure, so that
the new pick-up will not be susceptible to
the effects of static.
Set the pattern to “open” after the pick-up

CHECKING THE CD MECHANISM
Checking the operation of the CD mechanism
Disconnect the sled motor socket from the printed-circuit
board.
Apply avoltage of DC 0.7 Vto the sled motor’s
terminal.
Measure the current during sled motor operation.
●The direction of movement of the pick-up (Outer groove
or inner groove) can be changed by changing the battery
polarity.
The current during sled motor operation varies
according to the positional relationship of gears
(107 and 108).
If the current exceeds 20-50 mA ,remove the
gear (107 )and gear (108 ).
Apply asmall amount of aFLOIL (G-474B )bonding
materials to the chassis shafts.
Install the gears as shown in the illustration.

Resetting the pick-up to the home position
The LIMIT switch is switched ON by the projection
of the rack gear secured to the returned pick-up,
after which the sled motor continues to operate
(by the circuit) for approximately 20-30 milliseconds
there is then again areverse operation, and movement
to the position at which the switch is switched OFF.

PARTS LIST
PRODUCT SAFETY NOTICE .4
Each precaution in this manual should be followed during servicing. Components identified with the IEC symbol ~in the pa
Ilst and the schermatlc d!acjram designate components In which safety can be of special significance. when replaclng acompone
identified ~, use only the replacement parts designated, or parts with the same ratings of resistance, wattage or voltage that are
designated In the parts list In this manual, Leakage-current or resistance measurements must be made to determine that exposed
parts are acceptably ~nstilated from the supply c!rcuit before returning the product to the customer.
CAUTION: Regular type resistors and capacitors are not listed. To know those values, refer to the schematic diagram.
