General Radio Operation

the radio is currently in Direct mode (during conventional
operation only).
You can repeat step 2 to toggle between the two modes. Once
in Direct Mode, press PTT button to start conversation with the
radios nearby.
Monitoring Features
Radio users who switch from analog to digital radios often
assume that the lack of static on a digital channel is an
indication that the radio is not working properly. This is not the
case.
Digital technology quiets the transmission by removing the
“noise” from the signal and allowing only the clear voice or data
information to be heard.
Monitor a channel to ensure the channel is clear before
transmitting.
Monitoring a Channel
Procedure:
Lift the microphone off hook.
Conventional Modes Only:
