Points to notice for Disassembly / Assembly
Caution:
Whenever "Separation of Front and rear bodies", "Disassembly of CCD/FPC unit", or
"Disassembly of Bayonet" are performed, be sure to perform "RESET AF-DEFOCUS
COMPENSATION" of camera adjustment software after reassembling.
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 repair manuals.
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 fixed
and their types, etc.
④ Because the low pass filter of the imaging CCD PCB is easily damaged, handle it with enough care.
⑤ is indicated in this manual when NK screw is used. Usually the same "NK" screw can be used
approx. up to three times.
(NK screw = Loose-proofing screw to which the adhesive is already applied and firmly fixed when
screwed in.)
Points to notice for Lead-free solder products
・ Lead-free solder is used for this product.
・ For soldering work, the special solder and soldering iron are required.
・ Do NOT mix up lead-free solder with traditional solder.
・ Use the special soldering iron respectively for lead-free solder and lead solder.
They cannot be used in common.
