1.1 BEFORE ASSEMBLY AND DISASSEMBLY
1.1.1 Precautions
1. Be sure to remove the power supply unit prior to mount-
ing and soldering of parts.
2. When removing a component part that needs to disconnect
the connector and to remove the screw for removing itself,
first disconnect the connecting wire from the connector and
then remove the screw beforehand.
3. When connecting and disconnecting the connectors, be
careful not to damage the wire.
4. Carefully remove and handle the part to which some
spacer or shield is attached for reinforcement or
insulation.
5. When replacing chip parts (especially IC parts), desolder
completely first (to prevent peeling of the pattern).
6. Tighten screws properly during the procedures.
Unless specified otherwise, tighten screws at a torque
of 0.078N·m (0.8kgf·cm).

Extend the locks in the direction of the arrow for unlocking
and then pull out the wire. After removing the wire, immedi-
ately restore the locks to their original positions because the
locks are apt to come off the connector.
