SECTION 1

SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electro­static break-down because of the potential difference generated
by the charged electrostatic load, etc. on clothing and the human
body.
During repair, pay attention to electrostatic break-down 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 objecti ve lens.

Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270 ˚C dur-

ing 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.

CAUTION

Use of controls or adjustments or performance of
procedures other than those specified herein may
result in hazardous radiation exposure.

1-1. H OW T O OPEN THE DISC TRAY WHEN

POWER SWITCH TURNS OFF

1 Insert a tapering driver into the aperture of the unit bottom,
and move the limiter (LEVER) to direction of the arrow A.
2 Pull the tray to direction fo the arrow B.

1-2. PREPARATION FOR ADJUSTMENT AND

MEASUREMENT

Perform connecting the IC361 pin 2 of BD board to the line of
+5V because this unit does not work without the stabilizer struc­turally.

Connecting Location:
[BD BOARD] (SIDE B)

This appliance is classified as a CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT MARKING is located on
the rear exterior.

Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.
