I TO SERVICE PERSONNEL

Critical Components Information

Components having special characteristics are marked A. AC LEAKAGE
and must be replaced with parts having specifications equal WALL EQUIPMENT TESTER OR
to those originally installed. OUTLET UNDER TEST EQUIVALENT
2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify ® :D-
that all exposed conductive surfaces are properly insulated
from supply circuits. =
0 Meter impedance should be equivalent to 1500 ohm shunted INS1IJALBAJEING

by 0.1 SpF.
o Leakage current must not exceed 0.5mA.
0 Be sure to test for leakage with the AC plug in both polarities.

THE DVD PLAYER SHOULD NOT BE ADJUSTED OR REPAIRED BY ANYONE EXCEPT PROPERLY QUALIFIED
SERVICE PERSONNEL.

WARNING: CHEMICAL CONTENT NOTICE!

The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where
applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and
possibly other entities) to cause cancer and/or birth defects or other reproductive harm.

DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REA-
SON WHATSOEVER!

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
handling food.

WARNING: Laser Safety

This product contains a laser beam component. This component may emit invisible, as well as visible radiation, 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 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 performance 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 "POWER" SW is turned to the "ON" position, the laser component 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 set, 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 provided elsewhere in this
manual.

Adjustment of this control can increase the laser emission level from the device.
