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 1 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 LaserPower Output of thePickup inside the unit andreplacement service parts have alreadybeen 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.
IMPORTANT SERVICE NOTES (FOR U.K. ONLY)
Before returning the unit to the customer after completion of a
repair or adjustment it is necessary for the following withstand
voltage test to be applied to ensure the unit is safe for the
customer to use.

Notes:
1. Description of the "FM IF Adjustment" is not carried on this Manual. It is because the IF coil in the FM front end section has been
best adjusted in the factory so that its further adjustment is not
needed at the field. When replacing the FM front end assembly, no
adjustment is needed either.
2. The parts in the FM front end section are prepared in a complete
unit, so you can't obtain each part individually.
