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.
!
INC
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.
FSA03801-R.3756.A
Points to notice for Lead-free solder products
Note : Before disassembling, remove the battery.
When disassembling, make sure to memorize the processing state of wires, screws to be
xed and their types, etc.
③ Because electrical parts are easily damaged by static electricity, make sure that you are
well earthed/grounded.
