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, Eor 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 Eor siren and light operations, will be terminated.
Emergency Operation
Either control unit (active or idle controller) can declare an emergency, provided radio has been
Siren And Light Control
Siren and light control is only available from the control unit that is pre- programmed for these functions. Typically, the control unit at the driver's location 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.
