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,
or siren and
E
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
or siren and light operations, will be terminated.
E
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.
DUAL CONTROL AUDIO
Audio output during dual control operation is a pre-programmed function.
Default operation routes audio only to the active controller.
