9. CLEANING AND MAINTENANCE
Disconnect from mains before starting maintenance operation!
DANGER TO LIFE!
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 tighly
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 speaker-system. Please use a soft lint-free and moistened cloth.
Never use alcohol or solvents!
There are no servicable parts inside the device except for the fuse and battery. Maintenance and service
operations are only to be carried out by authorized dealers.
In order to replace the battery please refer to "Inserting/exchanging the batteries".
9.1 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: Unscrew the fuseholder on the rearpanel with a fitting screwdriver from the housing (anti-
clockwise).
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 and fix it.
9.2 Storage and maintenance of rechargeable batteries
When the device is not in use for a longer period of time, the rechargeable batteries have to be charged
every month. Otherwise danger of permanent power loss or battery damage.
Remove batteries from the housing if the temperature is below -5° C! Otherwise danger of battery damage.
Always store the rechargeable batteries in a warm enough, dry place where children cannot access.
When reinstalling the rechargeable batteries, make sure to connect the right poles of the connection cables.
If the Charging-LED does not flash when connecting the device with the mains, the poles are wrong or a
battery is defective.
