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.
