Warning
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 the lead-free solder with the conventional solder.
Use the special soldering iron respectively for lead-free solder and lead solder. They cannot
be used in common.

There are high voltage parts inside. Be careful of this electric shock,
when you remove the cover.
You must discharge the main condenser according to the instruction
of this repair manual after you remove the cover.
WARNING!
Caution:
①In disassembly/(re)assembly, be sure to use conductive mat (J5033) and wrist strap (J5033-5) in
order to protect electric parts from static electricity.
②Before disassembling, be sure to remove batteries orAC power cord.
③In disassembling, be sure to memorize the processing state of wires and FPCs, screws to be
xed and their types, etc.
④ The low-pass lter of the image CCD PCB is easily damaged. Handle it very carefully.
ref. In this manual, the application of grease and adhesive is indicated by coloring
CFD-409Z EDB0011
(grease: yellow/adhesive: red) or J-number.
Note:
①The prism box unit can be disassembled until the stage shown from page D26 to D28.
(ref. parts list)
②What are used in this manual may differ from the actual products in forms, etc.
