Before Disassembly / Assembly / Adjustment ...
Note:
① When disassembling, make sure to memorize the processing state of wires and FPC.
② Because prototypes are used for "Disassembly/(Re)assembly/Adjustment", they may differ from the actual
products in forms, etc.
③ Because pictures are processed by a special method, they may differ from the actual ones in texture.
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.
