I TO SERVICE PERSONNEL

. Critical Components Information
1Components 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 0.15jIF.

AC LEAKAGE
WALL EQUIPMENT TESTER OR
OUTLET UNDER TEST EQUIVALENT

C) i:%-

J;-

INSULATING
TABLE

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

THE DVD AUDIO/VIDEO 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

REASON 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 perfor-
mance 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
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 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
provided elsewhere in this manual. Adjustment of this
control can increase the laser emission level from the
device.
