SAFETY PRECAUTIONS
The following check should be performed for the continued
protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known earth ground (water
pipe, conduit, etc.) by connecting a leakage current tester
between the earth ground and all exposed metal parts of the
appliance (input/output terminals, screwheads, metal over-
lays, control shaft, etc.). Plug the AC line cord of the appli-
ance directly into a 120V AC 60Hz outlet and turn the AC
power switch on. Any current measured must not exceed
0.5mA.
ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A POTEN-
TIAL SHOCK HAZARD AND MUST BE CORRECTED
BEFORE RETURNING THE APPLIANCE TO THE CUS-
TOMER.

LASER BEAM SAFETY PRECAUTIONS
CLASS 1 LASER PRODUCT
DANGER
INVISIBLE LASER RADIATION
AVOID DIRECT EXPOSURE TO BEAM
This Receiver uses a pickup that emits a laser beam.
The laser beam is emitted from the location shown in the figure. When checking the laser diode, be sure to keep your eyes
at least 1 foot away from the pickup lens when the diode is turned on. Do not look directly at the laser beam.
Caution: Use of controls and adjustments, or doing procedures other than those specified herein, may result in hazardous
radiation exposure.
Do not look directly at the laser beam coming
from the pickup or allow it to strike against your
skin.

HANDLING LASER PICKUP
The laser diode in the optical system of this receiver can be damaged by electrostatic discharge from clothes,
body, etc. Proper electrostatic grounding for service personnel is required during servicing.
BEFORE REPAIRING THE DVD MECHANISM
a. Human Body Grounding:
Many of the components used in this compact disc player, including the laser pickup, are sensitive to electrostatic dis-
charge.
Service personnel should be grounded with an electrostatic armband (1M ohm).
Caution: Static charge on clothing does not escape through a body grounding wristband. Be careful not to contact the
pickup or electrical components with your clothing.
b. Workbench and Tool Grounding:
A properly-grounded electroconductive plate (1 M ohm) or metal sheet should be fitted to the workbench surface.
Tools and instruments (soldering irons, scopes, etc.) should be grounded to prevent AC leakage.
c. Make two standard ESD solder bridges on the Laser optic PC Board
Before disassembly of mechanism or disconnect any cables in it, make two standard ESD solder bridges on the laser
optic PC Board.
