Switching Control
Control can be switched to the idle controller by pressing the push-to-talk
(PTT) on the microphone associated with the idle controller. Once PTT is
pressed, the radio will switch control to the idle controller unless the active
controller is currently transmitting (i.e., PTT pressed on active controller), in
which case the switch will not occur. When control is switched to the idle
controller, two short high-pitched tones will sound at the controller where
PTT was pressed to indicate that the idle controller is now the active controller
and the previous active controller is now the idle controller.
Control Switching Modes
The radio can be pre-programmed for two modes of dual operation, Slaved
and Independent. In the Slaved mode the two controllers will use the same
radio System and Group settings. The Independent mode permits each
controller to have its own saved System and Group settings.
Slaved Mode Operation
During Slaved mode operation either controller can operate the radio with no
change in System and Group settings when control is switched. Both
controllers display the current information. If a key is pressed at the idle
controller, other than PTT,
E
or siren and light keys as noted in following
paragraphs, a low tone will sound and the display will temporarily show
DUAL
on line one of the idle controller.
When control is switched in a Slaved mode system, all of the radio settings
and states will remain in effect that have been selected on the active
controller.
Independent Mode Operation
During Independent operation, the radio system operates as if there are two
radio units each controlled by a separate control unit. Each control unit
maintains its own System and Group settings, which are restored when control
is switched.
The idle controller will display
DUAL
on line one to indicate that it is idle. If
a key is pressed at the idle controller, other than PTT,
E
or siren and light
keys as noted in following paragraphs, a low tone will sound at the idle
controller.
When control is switched in Independent mode, the idle controller will restore
its own System and Group settings instead of using the settings of the
previously active controller. Any pending operations at the active controller,
other than
E
or siren and light operations, will be terminated.
