What to do if my Sennheiser EM 550 G2 Receiver has RF signal but no audio and the mute light is on?

  If your Sennheiser Receiver shows an RF signal but no audio and the “MUTE” display is on, first, check if the transmitter is muted and deactivate the muting function. Also, the receiver’s squelch threshold might be set too high, or the transmitter might not be sending a pilot tone, so switch the pilot tone transmission on the transmitter on or switch the pilot tone evaluation on the receiver off. Finally, the transmitter sensitivity could be too low; adjust it accordingly.

  If your Sennheiser Receiver shows no RF signal, ensure that the transmitter and receiver are set to the same channel. Also, the transmitter might be out of range. In this case, check the squelch threshold setting or reduce the distance between the transmitter and the receiving antenna.

  If the audio signal from your Sennheiser Receiver has a high level of background noise, it could be due to the receiver’s AF output level being adjusted too low, or the transmitter sensitivity being adjusted too high. Adjust the transmitter sensitivity correctly.
