Attention: The laser diode of this CD drive is protected against ESD by a solder joint which short-circuits the laserdiode to ground. For proper functionality of the CD drive this solder joint must be removed after connecting the drive to the set.

In case of a Supply fault, the tray can be opened manually. 1. Remove the top cover of the set to get access to the Changer Module. 2. Turn gearwheel clockwise (as shown in picture below).
