CHAPTER 1. GENERAL DESCRIPTION

[1] 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 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 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 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.

[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.

3. 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 disc is changed, these adjustments are performed

automatically. Therefore, playback of each disc can be performed

under optimum conditions.
