Be sure to short this position
extremely sensitive to electrical shock.
(Use the shorting pin or clip.)
2. To prevent the breakdown of the laser diode, an anti-
static shorting pin is inserted into the flexible board.
(FPC board)
When removing or connecting the short pin, finish the
job in as short time as possible.
3. Take care not to apply excessive stress to the flexible
board. (FPC board)
