Maintenance - Raveland Boom 80 MkII Bedienungsanleitung

12. Maintenance

Check the technical safety of the subwoofer regularly, e.g. for damage to the connection cables or to 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 can 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
Always observe the following safety instructions before cleaning or servicing the subwoofer:
Live components may be exposed if the covering is opened or components are removed.
Before servicing or repair works, the subwoofer must be disconnected from all sources of
voltage.
Capacitors inside the device may still carry voltage even though they have been disconnected
from all voltage sources.
Repairs may only be carried out by qualified personnel who are familiar with the hazards involved
and the relevant regulations.
If you have to replace fuses, ensure that you only use replacement fuses of the same type and rated current (see
„Technical data").
It is absolutely impermissible to repair fuses or bridge the fuse holder.
• After disconnecting the appliance from the power source (by disconnecting the car power supply!), carefully remove
the FUSE (7) fuse from the fuse holder.
• Replace it by a fuse of the same type.
• Only then should the subwoofer be re-connected to the car system and put into operation.
