Instructions for Connectors
1. When you connect or disconnect the FFC (Flexible
Foil Connector) cable, be sure to first disconnect the
AC cord.
2. FFC (Flexible Foil Connector) cable should be in-
serted parallel into the connector, not at an angle.

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
solde r ing 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 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.
Lead-free solder contains more tin, and the end of the
soldering bit may be easily corroded. Make sure to turn
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.
Be careful when replacing parts with polarity indication
on the PWB silk.
