tional modes. Only one control unit can control the mobile radio unit at a
time. The control unit which controls the radio operation is called the active
controller and the second unit is called the idle controller.
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 control-
ler 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 con-
troller 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 con-
trollers display the current information. If a key is pressed at the idle control-
ler, other than PTT,
or siren and light keys as noted in following
E
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 control-
ler.
