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,
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 control-
ler.
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 con-
trol 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 re-
store 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.
Emergency Operation
Either control unit (active or idle controller) can declare an emergency, pro-
vided radio has been pre-programmed to enable emergency declaration. If
the idle controller declares an emergency, control is switched to the idle con-
troller and any current transmission from the previously active controller is
terminated.
Siren And Light Control
Siren and light control is only available from the control unit that is pre-pro-
grammed for these functions. Typically, the control unit at the driver’s loca-
tion would be programmed. The control unit that has these functions
programmed can activate them regardless of whether it is an active or an idle
controller.
