58 Dual radio operation
Radio controls in a dual radio
system
Certain radio controls and functions are global and
apply to the radio system as a whole. The on-off key
turns the entire radio system on or off. The volume
control adjusts the volume of all received audio and
indicators. Functions and menu options relating to the
radio display and audible indicators are also global.
Many other functions and menu options apply to the
foreground radio only. Examples include changing
channels and zones, and toggling monitor. See
“Switching between radios” on page 59
.
You can switch between the various dual receive and
transmit states using one or two function keys
programmed for dual body mode and single body
mode. If programmed for a single key, dual body
mode is assigned to a short press and single body
mode is assigned to a long press. The following
diagram summarizes how to enable dual receive and
dual transmit and how to return to single body mode.
