Use the
▼

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 SRM9000 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.
Where the default is not acceptable, it may be adjusted for analogue channels
