System information

Audio Mute Concealment is a receiver feature that masks
small gaps in audio that occur during frequency changes.
The default setting for AMC is On.
From the receiver menu: Audio > AMC
1. Use the control wheel to set AMC to On or Off.
2. Press Enter to save changes.
Squelch mutes the receiver output when transmitter signal is absent to prevent RF noise from entering the audio signal.
The Axient receiver uses both "noise squelch" and tonekey squelch to ensure that only the correct transmitter signal is
passed.
Noise Squelch
Noise squelch uses an adjustable threshold to detect the
transmitter RF signal. If the transmitter signal falls below
the threshold, the receiver output will be muted.
The noise squelch setting can be used in noisy RF
environments to prevent unwanted signals from entering
the audio signal.
To set the noise squelch from the receiver menu: Radio > Squelch
1. Use the control wheel to select and adjust the squelch level.
2. Press Enter to save changes.
Note: Within the Squelch menu there is an option to turn off tonekey squelch detection. Use this option to troubleshoot stray signals in the RF
environment. Be sure to turn the Tonekey Squelch On when finished troubleshooting.
Tonekey Squelch
Tonekey squelch uses a supra-audible tone generated by
the transmitter and sent with the audio signal to control the
squelch function. The receiver will mute the audio output if it
does not detect the tonekey signal sent by the transmitter.
