Troubleshooting

In the following we list a few common problems that may occur during operation. We give you

some suggestions for easy troubleshooting:

Symptom

Remedy

No sound

1. Check the power supply of transmitter and receiver.

2. Are transmitter and receiver set to the same channel?

3. Test the connection between the transmitter and the connected audio device (amplifier, mixer).

Is the connected audio device turned on and does the signal level at the output of the audio

device match to the input requirements of the transmitter?

4. See if the sound transmission works when you move the receiver closer to the transmitter.

Transmission is interrupted.

1. Make sure that no metal objects near the transmitter or receiver obstruct the transmission.

2. Modify the orientation of the antennas.

3. If you use more than one wireless system at the same time, check the used channels.
