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 30cm 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.

1. IMPORTANT SERVICE NOTES
BEFORE RETURNING THE DVD VIDEO PLAYER
Before returning the DVD video player to the user,
perform the following safety checks.
1. Inspect all lead dress to make certain that leads are
not pinched or that hardware is not lodged between
the chassis and other metal parts in the DVD video
player.
2. Inspect all protective devices such as non-metallic
control knobs, insulation materials, cabinet backs,
adjustment and compartment covers or shields, isola-
tion resistor/capacitor networks, mechanical insula-
tors etc.
3. To be sure that no shock hazard exists, check for
current in the following manner.
Plug the AC line cord directly into a 230 volt AC outlet
(Do not use an isolation transformer for this test).
Using two clip leads, connect a 1.5k ohm, 10 watt
resistor paralleled by a 0.15µF capacitor in series with
all exposed metal cabinet parts and a known earth
ground, such as a water pipe or conduit.
UseanDVM or VOMwith1000 ohmper volt, or higher,
sensitivity or measure the AC voltage drop across the
resistor (See Diagram).
Move the resistor connection to earth exposed metal
part having a return path to the chassis (metal cabinet,
screw heads, knobs and control shafts, etc.) and
measure the AC voltage drop across the resistor.
Reverse the AC plug on the set and repeat AC voltage
measurements for each exposed part. Any reading of
1.4Vrms (thiscorresponds to 0.7mArms AC.)or more
is excessive and indicates a potential shock hazard
which must be corrected before returning the DVD
video player to the owner.

Using lead-free wire solder
When fixing the PWB soldered with the lead-free solder,
apply lead-free wire solder. Repairing with conventional
lead wire solder may cause damage or accident due to
cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is
higherthanthe lead wire solderby40°C,we recommend
you to use a dedicated soldering bit, if you are not
familiar with how to obtain lead-free wire solder or
soldening bit, contact our service station or service
ranch in your area.
Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is
about 220°C which is higher than the conventional lead
solder by 40°C, and as it has poor solder wettabillty, you
may be apt to keep the soldering bit in contact with the
PWB for extended period of time. However, Since the
land may be peeled off or the maximum heat-resistance
temperature of parts may be excoeded, remove the bit
from the PWB as soon as you conurm the steady
soldering condition.
Lead-free solder contains more tin, and the end of the
soldering bit may be easily corroded. Make sure to tum
on and off the power of the bit as required. if a different
type of solder stays on the tip of the soldering bit, it is
alloyed with lead-free solder. Clean the bit after every
use of it.
When the tip of the soldering bit is blackened during
use, file it with steel wool or fine sandpaper.
Becareful when replacing parts with polarity indication
on the PWB silk.

Instructions for Handling
Semi-conductors
Electrostatic breakdown of the semi-conductors may
occurduetoapotentialdifferencecausedbyelectrostatic
charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1MΩ) 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 (1MΩ) 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.
