Notes
As the transmission quality depends on local conditions, please observe the following items for optimum
receiving:
• maintain a line-of-sight between the microphone/bodypack and the PA system.
• make sure the distance between the microphone/bodypack and the PA system is not too long.
• make sure the reception is not disturbed by objects in the transmission path; avoid placing the
microphone/bodypack and the receiver where metal or other dense materials may be present and
computers or other HF-generating equipment (min. 50 cm distance).
• make sure the capacity of batteries is always sufficient.
8 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. 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.
