In order to avoid damage, please reduce the volume immediately when distortions can be heard. When
speaker-systems are destroyed by overload, the guarantee becomes void.
Always check the sound pressure level with a meter in order to keep to the threshold.
If you want to switch off the system, switch off the amplifier first and then the pre-amplifiers in order to
avoid acoustic shocks on the speakers.
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 speaker-system. Please use a soft lint-free and moistened cloth.
Never use alcohol or solvents!
There are no serviceable parts inside the speaker-system. Maintenance and service operations are only to
be carried out by authorized dealers.
If the speaker-system distorts, one of the loudspeakers may be defective. Test the speaker-system once
more with another amplifier. If the sound remains distorted, 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. Especially for public use, the speaker-
system should be checked before every operation so that the speaker-system and the speakers in the
systems are always well fixed.
Should you need any spare parts, please use genuine parts.
Should you have further questions, please contact your dealer.
