AF audio level (audio frequency)



  • Displays the audio level of the received transmitter
  • When the display shows full deflection, the audio input level is excessively high (see Setting the input sensitivity (GAIN))
  • A noticeable audio level must be displayed
If no audio level is displayed:
  1. Switch on the transmitter (see Switching the transmitter on and off).
  2. Make sure that the same frequency is set on the transmitter and receiver (Establishing a radio link | Synchronizing devices).
  3. Check that the antennas and the antenna cables are correctly connected to the transmitter.
  4. Move the transmitter to a better location.
  5. If necessary, use an antenna booster.
