Dual Control Audio
Audio output during dual control operation is a pre-programmed function.
Default operation routes audio only to the active controller.
MULTIPLE RADIO OPERATION
Orion mobile radio may be configured to operate in a multiple radio mode
that permits more than one radio to be controlled from a single control unit
or control location. The radios could be different frequency splits,
trunked/conventional, etc.
In the multiple radio operation, the radios continue to operate as individual
radios except with a common control unit. The control unit is used for
display and control. The control unit display is shared by the multiple radio
units and, when selected, a radio can be controlled by the control unit.
For multiple radio operation the control unit keypad must be pre-
programmed for a variety of multiple radio buttons such as radio selection
and radio mute.
Changing Selected Radio
A radio unit may be selected by pressing the radio selection button (pre-
programmed) on the control unit. Also, a button may be pre-programmed
to rotate selection through the radio units; e.g., if radio #1 is selected,
pressing the radio select button will select radio #2. Similarly, radio #2 will
be selected if the radio select button is pressed when radio #1 was selected.
Shared Control Unit Display Modes
Radios in the multiple radio operation share the control unit display. Pre-
programming the radios determines what the control unit displays. There
are two modes of display: alternating radio display or first come first serve
display. See also the following paragraph on Audio Modes.
Alternating Radio Display
In this mode the control unit display will alternate between showing the call
information for the radios when more than one call is being received. This
mode is available only if audio is summed (see following paragraph on
Audio Modes).
