When the power supply is being turned on, you may not remove this laser cautions label. If it removes, radiation of laser
may be received.
LASER BEAM CAUTION LABEL
PREPARATION OF SERVICING
Pickup Head consists of a laser diode that is very susceptible to external static electrocity.
Although it operates properly after replacement, if it was subject to electrostatic discharge during replacement,
its life might be shortened. When replacing, use a conductive mat, soldering iron with ground wire,etc. to
protect the laser diode f
rom damage by static electricity.
And also, the LSI and IC are same as above.
Soldering iron
with ground wire
or ceramic type
Ground conductive
wrist strap for body.
Conductive mat
The ground resistance
between the ground line
and the ground is less than 10
1M

SAFTY NOTICE
Plug the AC line cord directly into a 120V AC outlet (do
not use an isolation transformer for this check). Use an
AC voltmeter, having 5000 per volt or more sensitivity.
Connect a 1500 10W resistor,paralleled by a 0.15uF
150V AC capacitor between a k
nown good earth ground
(water pipe, conduit, etc.) and all exposed metal parts of
cabinet (antennas, handle bracket, metal cabinet
screwheads, metal overlays, control shafts, etc.).
SAFTY PRECAUTIONS
LEAKAGE CURRENT CHECK
Measure the AC voltage across the 1500 resistor.
The test must be conducted with the AC switch on and
then repeated with the AC switch off. The AC voltage
indicated by the meter may not exceed 0.3V.A reading
exceeding 0.3V indicates that a dangerous potential
exists, the fault must be located and corrected.
Repeat the above test with the DVD VIDEO PLAYER
power plug reversed.
NEVER RETURN A DVD VIDEO PLAYER TO THE
CUSTOMER WITHOUT TAKING NECESSARY
CORRECTIVE ACTION.
READING SHOULD NOT EXCEED 0.3V

The lightning flash with arrowhead symbol, within an
equilateral triangle, is intended to alert the user to the
presence of uninsulated "dangerous voltage" within the
product's enclosure that may be of sufficient magnitude to
constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in the
literature accompanying the appliance.
