警告
Note： ① When disassembling/(re)assembling, be sure to use the conductive mat (J5033) and wrist strap
(J5033-5) for static protection of electrical parts.
② Before disassembling, be sure to remove batteries or AC power wires.
③ When disassembling, make sure to memorize the processing state of wires and FPC, screws to be
xed and their types, etc.
④ Because the low pass lter of the imaging CCD PCB is easily damaged, handle it with enough
care.
