is carried out.
Capacitors inside the device may still carry voltage even though they have been disconnected
from all power sources.
Only qualified experts familiar with the hazards involved and the relevant regulations may
perform repairs.
Apart from this, the device does not need any servicing. The outside should only be cleaned with a soft, dry cloth or
