I TO SERVICE PERSONNEL

1. Critical Components Information
Components having special characteristics are marked A
and must be replaced with parts having specifications equal
to those originally installed.

2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.

0 Meter impedance should be equivalent to 1500 ohms shunted
by 0.15m:

0 Leakage current must not exceed 0.5mA.
0 Be sure to test for leakage with the AC plug in both polari-
ties.

WARNING: CHEMICAL CONTENT NOTICE!

This product contains chemicals known to the State of California to cause cancer, or birth defects or other reproductive harm.
DO NOT PLACE SOLDEFI, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY

REASON WHAT SO EVER!

Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose

eyes to solder/flux vapor!

If you come in contact with solder or components located inside the enclosure of this product, wash your hands before

WARNING: Laser Safety

This product contains a laser beam component. This
component may emit invisible. as well as visible ra-
diation, which may cause eye damage. To protect
your eyes and skin from laser radiation. the following
precautions must be used during servicing of the unit.

1) When testing and/or repairing any component within
the product, keep your eyes and skin more than 30
cm/1 feet away from the laser pick-up unit at all times.
Do not stare at the laser beam at any time.

2) Do not attempt to readjust, disassemble or repair the
laser pick-up. unless noted elsewhere in this manual.

3) CAUTION: Use of controls. adjustments or perform-
ance of procedures other than those specified herein
may result in hazardous radiation exposure.

Laser Emitting conditions:

1) When the Top Cover is removed, and the STANDBY/
ON SW is turned to the "ON" position, the laser compo»
nent will emit a beam for several seconds to detect if a
disc is present. During this time (5-10 sec.) the laser
may radiate through the lens of the laser pick-up unit.
Do not attempt any servicing during this period!

If no disc is detected. the laser will stop emitting the
beam. When a disc is loaded, you will not be exposed
to any laser emiSsions.

2) The laser power level can be adjusted with the VR on
the pick-up PWB. however. this level has been set by
the factory prior to shipping from the factory. Do not
adjust this laser level control unless instruction is pro-
vided elsewhere in this manual. Adjustment of this con-
trol can increase the laser emission level from the
device.
