  If your Sennheiser Radio receiver shows no RF signal, it could be due to several reasons. First, ensure that the transmitter and receiver are set to the same channel and frequency. If they aren't, adjust them accordingly. Another cause might be the distance between the transmitter and receiver; try reducing this distance. Also, the squelch threshold setting should be checked by a technical expert.

  If the line signal from your Sennheiser Radio has a high level of background noise, it could be due to a couple of reasons. The transmitter’s line sensitivity might be adjusted too low; in this case, increase the line sensitivity via the “SENSIT (LINE)” menu. Alternatively, the transmitter’s microphone signal might be interfering with the line signal, so try muting the transmitter’s microphone (“MUTE”).
