SAFETY PRECAUTION FOR
SERVICE MANUAL
Precaution to be taken when replacing and servicing the
Laser Pickup.
The AEL (Accessible Emission Level) of Laser Power Output
forthis model isspecified to be lowerthan 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
outerthan the lead-in position. the Laserwill Iightfor 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.
