6. OPERATION
1
Prior to switching on, turn the control VOLUME to minimum to avoid a possible switching-on noise.
Then switch on the speaker system with the power switch. The front power indicator lights.
2
Adjust the overall volume with the control VOLUME.
3
Adjust the desired sound with the tone controls. By adjusting the tone controls, the high frequencies
(control TREBLE) and the low frequencies (control BASS) can be boosted or attenuated.
4
When operating the speaker system, please make sure that the loudspeakers always sound well. When
distortions can be heard, either the amplifier or the loudspeakers are overloaded. Overloads can quickly
lead to amplifier or speaker damage. 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.
5
After operation, set the control VOLUME to minimum, then switch off the speaker system with the
power switch. The power indicator extinguishes.
7. CLEANING AND MAINTENANCE
Disconnect from mains before starting maintenance operation!
DANGER TO LIFE!
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 device except for the fuse. 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. Then 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.
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.
