Disassembly

WARNING

Due to an internal high voltage area, take extra care not to get an electric shock when detaching covers.

After removing covers, be sure to discharge the main condenser according to the instructions of the repair manuals.

Note When disassembling/(re)assembling, be sure to use the conductive mat (J5033) and wrist strap (J5033-5) for static protection of electrical parts.

Before disassembling, be sure to remove batteries orAC power wires.

When disassembling, make sure to memorize the processing state of wires and FPC, screws to be fixed and their types, etc.

Because the low pass filter of the imaging CCD PCB is easily damaged, handle it with enough care.
