Warning for power supply

The primary side of the power supply carries live mains voltage when the player is connected to the mains even
when the player is switched off !
This primary area is not shielded so it is possible to accidentally touch copper tracks and/or components when servicing
the player.
Service personnel have to take precautions to prevent touching this area or components in this area.
Note:
The screws on the DVD mechanism may never be touched, removed or re-adjusted.
Handle the DVD mechanism with care when the unit has to be exchanged!
