7 Cleaning and Maintenance

We recommend a frequent cleaning of the PA system. Disconnect the device from power before cleaning.
Please use a soft lint-free and moistened cloth. Never use alcohol or solvents as these may damage the
surface. Make sure that no liquids can enter the device.
If the speaker system distorts, one of the loudspeakers may be defective. In this case the PA system should
not be operated any more in order to prevent further damage. Please contact your dealer. If clacking sounds
are heard from the speaker system, screws may have loosened due to the continuous vibrations. The
speaker system should be checked by a specialist.
There are no serviceable parts inside the device except for the fuse with model BOB-10A. Maintenance and
service operations are only to be carried out by authorized dealers. Should you need any spare parts, please
use genuine parts. If the power supply cable of this device becomes damaged, it has to be replaced by a
special power supply cable available at your dealer. Should you have further questions, please contact your
dealer.
Replacing the fuse (model BOB-10A)
If the fine-wire fuse of the device fuses, only replace the fuse by a fuse of same type and rating. Before
replacing the fuse, unplug mains lead.
Procedure:
Step 1: Open the fuseholder on the rear panel with a fitting screwdriver.
Step 2: Remove the old fuse from the fuseholder.
Step 3: Install the new fuse in the fuseholder.
Step 4: Replace the fuseholder in the housing.
