CHAPTER III DISASSEMBLY & REASSEMBLY
■
Safety Precautions
(1) You should carry out disassembly & reassembly jobs on an anti-static sheet
grounded correctly. Otherwise, the LSI and other electronic devices will 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.
