Notes on chip component replacement
¥ Never reuse a disconnected chip component.
¥ Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing
¥ Keep the temperature of soldering iron around 270ûC during repairing.
¥ Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).
¥ Be careful not to apply force on the conductor when soldering or unsoldering.

SERVICING NOTE
HOW TO OPEN THE DISC TRAY WHEN POWER SWITCH
TURNS OFF
Insert a screwdriver into the aperture of the unit bottom, and
move it in the direction of arrow.
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer
electrostatic breakdown because of the potential difference
generated by the charged electrostatic load, etc. on clothing and
the human body.
During repair, pay attention to electrostatic breakdown and also
use the procedure in the printed matter which is included in the repair
parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATION CHECK
Carry out the ÒS curve checkÓ in ÒCD section adjustmentÓ and
check that the S curve waveform is output three times.
