Analogue Mute Screen

The mute adjustment will be applied to all the radio’s analogue channels.

Use the ▼ and ▲ keys to adjust the mute threshold. A numeric value of the present mute

level is shown.

The “OK” key returns to the default channel screen with the selected mute setting.

It is recommended that the default mute setting of 4 be used. The SRP9100 series radios

have a carrier noise mute and this means the mute will open at the point where an analogue

signal is sufficiently noise free to be intelligible with a setting of 4.
