• Be sure to disconnect the power supply unit prior to mounting
and soldering of parts.
• Prior to removing a component part that needs to disconnect
its connector(s) and its screw(s), first disconnect the wire(s)
from the connector(s), and then remove the screw(s).
• When connecting/disconnecting wires, pay enough attention
not to damage the connectors.
• When inserting the flat wire to the connector, pay attention to
the direction of the flat wire.
• Be careful in removing the parts to which some spacer or
shield is attached for reinforcement or insulation.
• When replacing chip parts (especially IC parts), first remove
the solder completely to prevent peeling of the pattern.
• Tighten screws properly during the procedures. Unless
specified otherwise, tighten screws at a torque of 0.088N
·cm). However, 0.088N·m (0.9kgf·cm) is a value at the
(0.9kgf
time of production. At the time of service, perform the
procedure at a torque 10% less than 0.088N
·m (0.9kgf·cm).
(See "SERVICE NOTE" as for tightening torque.)

· Pull the both ends of the board in the direction of the arrow, and remove the B-B Connector.
FPC Connector
· Extend the locks in the direction of the arrow for
unlocking and then pull out the wire. After
removing the wire, immediately restore the locks
to their original positions because the locks are
apt to come off the connector.
