REPLACEMENT OF CD-DRIVE DA23-LNPH (3103 309 05320)
––––––––––––––––––––––––––––––––––––––––––––––––––––––
ATT: The laser diode of the DA23-LPH is protected against ESD by
a solder joint which shortcircuits the laser diode to ground.
For proper functionality this solder joint must be removed before
connecting the drive to the printed circuit board.
