SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECK
Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
resistance check. if the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power
cord is less than 460 kohms, the unit is defective.

LASER BEAM SAFETY PRECAUTIONS
This BD 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.

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)

antenna terminals, video and audio input and output
terminals, microphone jacks, earphone jacks, etc.) is
lower than or equal to the specified value in the table

Instructions for Handling Semi-
conductors
Electrostatic breakdown of the semi-conductors may
occur due to a potential difference caused by
electrostatic charge during unpacking or repair work.

1. Ground for Human Body
Be sure to wear a grounding band (1 M ) that is
properly grounded to remove any static electricity that
may be charged on the body.

2. Ground for Workbench
Be sure to place a conductive sheet or copper plate
with proper grounding (1 M ) on the workbench or
other surface, where the semi-conductors are to be
placed. Because the static electricity charge on
clothing will not escape through the body grounding
band, be careful to avoid contacting semi-conductors
with your clothing.
