SAFETY PRECAUTION FOR SERVICE MANUAL
zThis product is classified as a CLASS 1 LASER PRODUCT.
zWARNINGS:
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. So 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 adjustment, or performance of procedures other than those specified
