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

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.

(Except for UK)

Since this CD system incorporates the following automatic adjustment function, when the pickup is replaced, it is not necessary

to readjust it.

Since this CD unit does not need adjustment, the combination of PWB and laser pickup unit is not restricted.

• Automatic adjustment item

2. Tracking offset (Fig. 11-3)

3. E/F balance (tracking error balance) (Fig. 11-4)

5. RF level automatic follow-up of the tracking gain

This automatic adjustment is performed each time a disc is changed. Therefore,

each disc is played back using the optimal settings.

NOTES ON SCHEMATIC DIAGRAM

• Resistor:

To differentiate the units of resistors, such symbol as K and

M are used: the symbol K means 1000 ohm and the symbol

M means 1000 kohm and the resistor without any symbol is

ohm-type resistor. Besides, the one with “Fusible” is a fuse

type.

• Capacitor:

To indicate the unit of capacitor, a symbol P is used: this

symbol P means micro-micro-farad and the unit of the

capacitor without such a symbol is microfarad. As to

electrolytic capacitor, the expression “capacitance/withstand

voltage” is used.
