Warning for power supply

The primary side of the power supply including the heatsink 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 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 .
The primary side of the power supply has been indicated with a lightening stroke and a stripe-marked print on the printed
wiring board
Note:
The screws on the DVD mechanism (position 18-1 in on the exploded view drawing) may never be touched,
removed or re-adjusted.
Handle the DVD mechanism with care when the unit has to be exchanged!
The DVD mechanism is very sensitive for dropping or giving shocks.
