MICROPHONE GAIN

The microphone gain controls the sensitivity of the microphone to your voice

input level. If you are quietly spoken or are operating in a quiet environment you

can increase the microphone gain to make your voice sound clearer. If your voice

is quite loud or you are working in a noisy environment and wish to minimise the

amount of background noise that is picked up, you should reduce the microphone

gain.

To adjust microphone gain:

1. Press the MENU key.

2. Navigate through the menu to select RADIO SETTINGS > MIC GAIN.

You can use the

or key to increase or decrease the

microphone gain.

NOTE: The Microphone Gain provides a ‘ne’ adjustment to the microphone

sensitivity. A wider adjustment range is available through the XRS Connect App.

SQUELCH TAIL

The Squelch Tail is the short burst of noise that is heard in the speaker at the

end of a transmission just before the Squelch closes. To some it is a reassuring

conrmation that it is their turn to transmit but in some applications it may be an

annoyance especially when listening through an ear piece or headphones.

The Squelch Tail can be turned o, reducing it to a faint click as the Squelch

closes.

To enable/disable squelch tail:

1. Press the MENU key.

2. Navigate through the menu to select RADIO SETTINGS > SQUELCH

TAIL.

You can use the MENU key to turn this function on or o.
