Maintenance
Regularly check the technical safety of the SD tuner, e.g. for damage of 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 are to
be taken to ensure that it is not used unintentionally. Disconnect the car power system!
It must be assumed that safe operation is no longer possible if:
•
the device shows visible damage
•
if the appliance does not function for some reason, or
•
following considerable stress during transportation.
Before cleaning the SD tuner or performing maintenance, the following safety instruction must be observed:
Live components may be exposed if covers are opened or components are removed.
The device must be disconnected from all power sources before any servicing or repair work
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.
Replacing the Fuse
If it becomes necessary to replace a fuse, make sure that only fuses of the prescribed type and nominal current are
used (see "Technical Data").
Never 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 plug.
•
Replace it by a fuse of the same type.
•
Only then can you re-connect the SD tuner to the electric on-board system.
•
Should the fuse trigger again, have the CD tuner repaired in a specialised workshop.
