11. Maintenance and Care

Regularly check the technical safety of the PA speaker set, e.g. for damage to the mains cable or the casing.
If it can be assumed that safe operation is no longer possible, the system must be turned off and precautions are to
be taken to ensure that it is not used unintentionally. Pull the mains plug from the mains socket!
Always observe the following safety information before cleaning or servicing the PA speaker set:
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 must perform repairs.
a) Fuse Replacement
If the fuse must be replaced, observe that only fuses of the indicated type and rated current (see Technical Data)
must be used.
Never repair fuses or bridge the fuse holder.
• After mains disconnection (pull the mains plug!), pull the low-voltage plug from the mains connection (14) at the
device. Lever out the fuse holder at the mains connection (14) with the defective fuse.
• Remove the defective fuse and replace it with a fuse of the same type.
• Now carefully re-insert the fuse holder with the new fuse.
• Only then connect the mains line to the device again and plug into a mains socket.

b) Cleaning

The outside of the PA speaker set components should be cleaned with a soft, dry cloth or a brush only. You can clean
off the carpet cover of the casing with a vacuum cleaner.
Never use any aggressive cleaning agents or chemical solutions as these may damage the surface of the casing.
