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
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

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.
The voltage selector is located on the AC voltage selector box. If adjustment is necessary, ensure to remove plug of AC cord from
