Maintenance - Conrad Electronic FS8 Notice D'emploi

12. Maintenance

Check the technical safety of the subwoofer regularly, e.g. for damage to the connecting cables or to the casing.
If it can be assumed that safe operation is no longer possible, the device must be turned off and precautions must
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
Always observe the following safety instructions before cleaning or servicing the subwoofer:
Live components may be exposed if covers are opened or components are removed.
Before servicing or repairing the subwoofer, it must be disconnected from all power sources.
Capacitors inside the device may still carry voltage even though they have been disconnected
from all power sources.
Only qualified specialists familiar with the hazards involved and the relevant regulations may
perform repairs.
If you have to replace the fuse, ensure that you only use fuses of the specified type and rated current (see
„Specifications").
It is inadmissible to repair fuses or bridge the fuse holder.
• After disconnecting the power source (by disconnecting the on-board power supply!), carefully remove the FUSE
(8) from the fuse holder.
• Replace it with a fuse of the same type.
• Only then should the subwoofer be re-connected to the on-board system and put into operation.
