2.2 DISASSEMBLY AND REASSEMBLY

n Safety Precautions
(1) The disassembly or reassembly work should be carried out on a grounded antistatic
sheet. Otherwise, the LSIs and electronic parts may be damaged due to the electricity
charged in your body.
(2) When transporting PCBs, be sure to wrap them in conductive sheets such as
aluminum foil.
(3) When using soldering irons and other heat-generating tools, take care not to damage
the resin parts such as wires, PCBs, and covers.
(4) Be careful not to lose screws, washers, or other parts removed for parts replacement.
(5) Tighten screws to the torque values listed below.
