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.

BEFORE RETURNING THE DVD VIDEO PLAYER
Before returning the DVD video player to the user, perform
the following safety checks.

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
higher than the lead wire solder by 40°C, we recommend
you to use a dedicated soldering bit, if you are not familiar
with how to obtain lead-free wire solder or soldering bit,
contact our service station or service branch 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 wettability, 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 exceeded, remove the bit
from the PWB as soon as you confirm the steady
soldering condition.

(2) Remove the flat pack-IC with tweezers while apply-
ing the hot air.
(3) Bottom of the flat pack-IC is fixed with glue to the

soldering iron to center of the flat pack-IC and heat
up. Then remove (glue will be melted). (Fig. S-1-6)

Caution:
1. Do not supply hot air to the chip parts around the flat
pack-IC for over 6 seconds because damage to the
chip parts may occur. Put masking tape around the
flat pack-IC to protect other parts from damage.
