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 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 9 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.
CAUTION
- Visible and invisible laser
radiation when open. Avoid exposure to beam.
