Recommended Dual-Radio Settings
The programming configuration of all devices must be as similar as
possible, with the exception of the operating band, radio name, channels
and groups. If features relating to the user interface (such as function keys,
radio menus, and backlighting), and other features like the security lock are
different, there may be unexpected behaviour when powering on or
switching between the radios.
The following settings are recommended for a dual-radio system. Use this
table when setting up a template file, before programming the system (see
“Programming a Dual-Radio System” on page 38
).

PTT fields
PTT form
PTT settings for both radio bodies are used
when in dual-transmit mode and the radio user
presses the PTT. Care should be taken if
programming PTT behaviour differently between
the radio bodies. PTT settings are typically set
the same for all devices in the system.
Startup (Channel or
Group)

radio (the radio body with the lowest NTID) to
start on a specific channel or group each time
the radio system is turned on. You can also
program this option for the background radio to
default to a specific channel or group after the
radio system is turned on, and the radio user
subsequently switches the active radio or
enables dual receive.
Key Settings
Function Ctrl Settings form Add the Dual Body Mode and Single Body Mode
actions to separate keys, or Dual/Single Body
Mode to a single key. (recommended)
Add the Switch Active Radio action to a different
function key.
