LASER BEAM SAFETY PRECAUTIONS
This DVD player uses a pickup that emits a laser beam.
Do not look directly at the laser beam coming
from the pickup or allow it to strike against your
skin.
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 30 cm 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.

connectors, first, disconnect the AC plug from the
Precautions during Servicing AC outlet.
A. Parts identified by the # symbol are critical for
safety. Replace only with part number specified.
B. In addition to safety, other parts and assemblies
are specified for conformance with regulations
applying to spurious radiation. These must also be
replaced only with specified replacements.
Examples: RF converters, RF cables, noise
blocking capacitors, and noise blocking filters, etc.
C. Use specified internal wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
D. Use specified insulating materials for hazardous
live parts. Note especially:
1) Insulation tape
2) PVC tubing
3) Spacers
4) Insulators for transistors
E. When replacing AC primary side components
(transformers, power cord, etc.), wrap ends of
wires securely about the terminals before
soldering.
F. Observe that the wires do not contact heat
producing parts (heat sinks, oxide metal film
resistors, fusible resistors, etc.).
G. Check that replaced wires do not contact sharp
edges or pointed parts.
H. When a power cord has been replaced, check that
5 - 6 kg of force in any direction will not loosen it.
I. Also check areas surrounding repaired locations.
J. Be careful that foreign objects (screws, solder
droplets, etc.) do not remain inside the set.

Safety Check after Servicing
Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts, and
wires have been returned to their original positions. Afterwards, do the following tests and confirm the specified
values to verify compliance with safety standards.
1. Clearance Distance
When replacing primary circuit components, confirm
specified clearance distance (d) and (d') between
soldered terminals, and between terminals and Chassis or Secondary Conductor
surrounding metallic parts. (See Fig. 1)
