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.
.T’he direction of movement of the pick-up (outer groove or
inner groove) can changed by changing the battery polarity.
The current during sled motor operation varies
according to the positional relationship of gears
(11 Oandll l).
If the current exceeds 20-50 mA ,remove the
gear (lll)andgear(ll O).
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 a
reverse operation, and movement to the position at which
the switch is switched OFF.
Rotation continues for about 20- 30 milliseconds after the
switch is switched OFF, and then the pick-up stop at home
position.

PARTS LIST
PRODUCT SAFETY NOTICE d
Each precaution in this manual should be followed during servicing. Components identified with the IEC symbol ~in the parts list
and the schematic diagram designate components in which safety can be of special significance. When replacing acomponent
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 insulated from the supply circuit before returning the product to the customer.
CAUTION :Regular type resistors and capacitors are not listed. To know those vakses, refer to the schematic diagram.
Regular type resistors are less than l/4W carbon type and Oohm chip resistors.
Regular type capacitors are less than 50V and less than 1000PF type of Ceramic type and Electrical type.
