GENERAL DESCRIPTION 1 SAFETY PRECAUTION FOR SERVICE MANUAL Precaution to be taken when replacing and servicing the Laser Pickup. The

7、AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class 1 Requirements. However, the follow- ing 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

8、turned on without a compact disc, and the Pickup is on a position outer than the lead-in posi- tion, 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 ad

9、justed 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 her

10、ein may result in hazardous radiation exposure. 2 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.

CD SECTION Adjustment Since this CD system incorporates the following automatic adjust- ment functions, readjustment is not needed when replacing the pickup. Therefore, different PWBs and pickups can be combined freely. Each time a di
