Disassembly

! WARNING

There are high voltege 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.

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.

Note : Before disassembling, remove the SD card and battery.

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

Because electrical parts are easily damaged by static electricity, make sure that you are well earthed/grounded.
