SAFETY PRECAUTION FOR SERVICE MANUAL

The AEL (ACCESSIBLE EMISSION LEVEL) of the laser power output is less than class 1 but the laser component is capable of
emitting radiation exceeding the limit for class 1. Therefore it is important that the following precautions are observer during
servicing to protect your eyes against exposure to the laser beam.

(1) When the unit case cover is removed and LOADING SW (SW1932) is turned on and then PLAY SW (SW1934 mechanism PWB)

is turned on in a few second.
The laser will light for several second to detect a disk.

(2) The laser power output of the pickup unit and replacement service parts are all factory preset before shipment.

Do not attempt to readjust the laser pickup unit during replacement or servicing.

(3) Under no circumstances stare into the pickup lens at any time.
(4) If laser optical unit becomes faulty, replace the complete laser optical unit.
(5) CAUTION-USE of controls or adjustments, or performance of procedures other than those specified herein may result in

hazardous radiation exposure.

Precaution to be taken when replacing and servicing the laser pickup.
The following precautions must be observed during servicing to protect your eyesvagainst exposure to the laser.
Warning of possible eye damage when repairing:
If the AC power plug is connected when the inner cover of the unit is removed, the laser will light up during focus  access (about
1 second) (Fig. 2-1).
During this operation, the laser will leak from the opening between the magnetic head and cartridge holder (Fig. 2-2).
In order to protect your eyes, you must not look at the laser during repair.
Before repairing, be sure to disconnect the AC power plug.
