Precaution to be taken when replacing and servicing the Laser Pickup.
The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class I Requirements.
However, the following precautions must be observed during servicing to protect your eyes against exposure to the laser beam.
(1) When the cabinet has been removed, the power is turned on without a compact disc, and the Pickup is on a position

outer than the lead-in position, the Laser will light for several seconds to detect a disc. Do not look into the Pickup Lens.

(2) The Laser Power Output of the Pickup inside the unit and replacement service parts have already been adjusted prior

to shipping.

(3) No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup.
(4) Under no circumstances look directly into the Pickup Lens at any time.
(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 eyes against exposure to the laser.
Warning of possible eye damage when repairing:
If the AC adaptor or batteries are connected when the top houising (disc cover) of the unit is removed, and the PLAY key is
pressed, the laser will light up during focus access (2-3 seconds). (Fig. 2-1) During the operation, the laser will leak from the
opening between the magnetic head and the mechanical chassis (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 adaptor and remove the batteries.
