Muting the transceiver
When the transceiver is set to a channel or is scanning channels, and mute is switched
off, you hear on-air signals on each channel. If you do not want to listen to this, you
can silence the transceiver by switching on mute.
You can set the mute to switch off when a voice signal or any other calling activity is
detected (Voice mute V), or only when a call addressed to your station is received
(Selcall mute S). Your choice of Voice or Selcall mute depends on whether or not you
have to detect voice signals, and how much noise and traffic you want to hear. If you
have a digital voice encryptor fitted and active, you can also set the mute to switch off
only when a digitally encrypted voice signal is detected (Digital Voice mute D).
By default, mute automatically switches on when the transceiver starts scanning. The
transceiver listens for signals according to what is set in Settings > Scan Mute.
If the scan is paused due to voice being detected, the length of time that the transceiver
holds the pause with mute off is set in Settings > Scan Voice Max Pause and
Scan Voice Extend. Scanning only resumes automatically if the transceiver is set
to start scanning after a timeout period.
