8. CLEANING AND MAINTENANCE

The operator has to make sure that safety-relating and machine-technical installations are inspected by an
expert after every four years in the course of an acceptance test.
The operator has to make sure that safety-relating and machine-technical installations are inspected by a
skilled person once a year.
The following points have to be considered during the inspection:
1) All screws used for installing the speaker systems or parts of the speaker system have to be tightly
connected and must not be corroded.
2) There must not be any deformations on housings, fixations and installation spots (ceiling, suspension,
trussing).
3) The electric power supply cables must not show any damages, material fatigue (e.g. porous cables) or
sediments. Further instructions depending on the installation spot and usage have to be adhered by a
skilled installer and any safety problems have to be removed.
We recommend a frequent cleaning of the device. Please use a soft lint-free and moistened cloth. Never use
alcohol or solvents!
There are no serviceable parts inside the device except for the fuse. 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.
8.1 Replacing the Fuse
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.
8.2 Loudspeakers
If the speaker system distorts, one of the loudspeakers may be defective. In this case the speaker 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.
DANGER TO LIFE!
Disconnect from mains before starting maintenance operation!
