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.
