Outline of Assemble and Disassemble

1. Caution

1. Be sure to use the anti-static mat and wrist strap to prevent static failure of circuits.

2. This product is used lead free solder.

Surface of solder will be white-tinged color. Solder quickly, because melting temperature is high and so if

heat too much, it is possible to damage to PC board. Soldering iron requirement: The temperature can be

adjusted up to 400℃ and exclusive use for lead free solder. Also it is desirable to use antistatic soldering

iron. The temperature for tip of soldering iron must set between 340℃～360℃ for lead free solder.

3. Do not stress to the connector terminals and flexible boards because they are very delicate parts. Pay

careful attention to the connector terminals and flexible boards and, we recommend marking to the flexible

board before disconnecting them. This will be helpful to reconnect the flexible board to the connector

terminal properly.

4．Paste parts of that tape and etc. Follow the instructions in the service manual paste, so there is no float or

drift. Specially, there is a risk of a short copper foil tape and gaskets to connector.

（If adhesive tape of glue weaken, it must replace to new one.）
