Analogue Channel Monitor Mode:
The radio will receive any Analogue voice or DMR signals. Digital CC or Analogue CTCSS is

When normal mute is selected, the radio will receive correctly addressed Analogue radio
transmissions and all decryptable or clear DMR transmissions. An “N” icon indicates Normal.
Pressing the “
OK
” key returns to the main channel screen.
Pressing the “Back” or “Menu” key returns to the next highest menu level
4.2.3 Mute Adjust
From the menu list, step through the menu options with the ▼ and ▲ keys until the “Mute
Adjust” menu is displayed.
Press the “OK” key for the Mute adjustment screen.
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 is used. The SDM600 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.
Other settings are as follows:
0 no muting
4 normal setting,
8 will only hear reasonably strong signals
15 will only hear very strong signals.
Pressing the “OK” key will exit to the Channel Screen with the selected mute setting.
Direct access to the “Mute Adjust” screen from other screens can also be programmed to
one of the function buttons with the Field Programmer.
