I TO SERVICE PERSONNEL

1. Critical Components Information

. . . . AC LEAKAGE
Components havrng spectal characteristics are marked A WALL EQUIPMENT TESTER OR
and must be replaced with parts having specifications equal OUTLET UNDER TEST EQUIVALENT
to those originally installed.
2. Leakage Current Measurement (For 120V Models Only) ® :3-
When service has been completed, it is imperative to verify ,
that all exposed conductive surfaces are properly insulated : :
from supply circuits. INSULATING
TABLE
0 Meter impedance should be equivalent to 1500 ohm shunted
by 0.15%.
o Leakage current must not exceed 0.5mA. 0 Be sure to test for leakage with the AC plug in both

polarities.

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 the laser beam at any time.

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

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

Laser Emitting conditions:

1) When the Top Cover is removed, and 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 I
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
emussrons.

2) The laser power level can be adjusted with VR on 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 instruuction is provided elsewhere in this manual.
Adjustment of this control can increase the laser emission level from the device.
