DISASSEMBLY
Front cover, Rear cover
Note: ① Be sure to remove the SD memory card and batteries before disassembly.
② 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.
・ Take out 2 screws ( ①: M1.4×3).
・ Take out 3 screws ( ②: M1.7×4).
・ Take out 2 screws ( ③: M1.7×2.5).
・ Take out 1 screws ( ④: M1.7×3.5).
・ While pushing in the direciton of (↓), open the rear cover ( ⑤) to remove the connector ( ⑥).
・ Remove the front cover ( ⑦).
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.
