Maintenance

Regularly check the technical safety of the CD tuner, e.g. for damage to the cables or the housing.
If it can be assumed that safe operation is no longer possible, the device must be turned off and precautions must
be to be taken to ensure that it is not used unintentionally. Disconnect the on-board supply system!
It can be assumed that safe operation is no longer possible if:
• the device shows visible damage
• the device does not function any more, or
• following considerable mechanical stress
Before cleaning the CD tuner or servicing it, the following safety instruction must be observed:
Live components may be exposed if the covering is opened or components are removed.
The device must be disconnected from all power sources before carrying out any servicing or
repair work.
Capacitors inside the device may still carry voltage even though they have been disconnected
from all voltage sources.
Only qualified specialists familiar with the hazards involved and the relevant regulations may
perform repairs.
If the fuse has to be changed, make sure that only fuses of the designated type and nominal current are used (see
„Specifications").
It is inadmissible to repair fuses or bridge the fuse holder.
• When the power supply has been disconnected (disconnect ISO plug!), carefully remove the fuse from the fuse
holder next to the ISO terminal.
• Replace it with a fuse of the same type.
• Only now may you re-connect the CD tuner to the on-board supply system and operate it.
• Should the fuse be triggered again, take the device to a specialised workshop for repair.
Apart from this, the device does not need any servicing. The outside should only be cleaned with a soft, dry cloth or
a brush.
Never use caustic cleaning agents or chemical solutions, as the surface of the housing may be damaged.
