Regularly verify technical safety of the subwoofer, e.g. for damage to the mains cable and casing.
If it can be assumed that safe operation is no longer possible, the subwoofer 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!
It can be assumed that safe operation is no longer possible if:
• the
device is visibly damaged
• the
device no longer works
• the
device was stored under unfavourable conditions for an extended period of time or
• after
exposure to extraordinary stress caused by transport
Before cleaning or servicing the subwoofer, always observe the following safety information:
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
per
-
form 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 inlet connector from the mains connection (10) at the
device. Lever out the fuse holder at the mains connection (10) 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
Only
clean the subwoofer‘s outside with a soft, dry cloth or brush.
Never
use any aggressive cleaning agents or chemical
solutions as these may damage the surface of the casing.
