Troubleshooting
By purchasing the complete radio microphone set, you have acquired a product which has been designed to the state
of the art and is operationally reliable. Nevertheless, problems or faults may occur. Therefore, we would like to
describe how to eliminate possible faults here:
Please observe the safety instructions!
Device does not work after the POWER switch (2) has been switched on.

A transmitter cannot be switched on.
• The batteries are flat. Replace the batteries.
There is some interference with the radio transmission or there is no reception.
• There is a strong source of interference (e.g. radio devices, computer, strong electric motors) in the vicinity of the
transmitters or receiver.
• There are radio wave barriers in the transmission path (metal surfaces, reinforced concrete walls, etc.).
• The system range is exceeded.
• The transmitter batteries are flat.
• Another radio-based device interferes with transmission. Try another channel setting.
• The aerials are not ideally aligned. Try realigning the aerials.
