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 can be selected by pressing the radio selection button (pre-

programmed) on the control unit. In addition, a button can 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).

First-Come First-Serve Display

In this mode, the control unit display will show the call information of the

radio that is providing the audio. A call in process prevents audio from other

radios from being heard for the duration of the call. This mode corresponds

with the first-come first-serve audio mode (see following paragraph on Audio

Modes).

Audio Modes

In multiple radio operation, the audio from the mobile radio units can be pre-

programmed to be summed or available on a first-come first-serve process.

Audio Summed

When audio is summed, the audio from all radios will be available whenever

the radios receive a call. If two radios receive a call simultaneously, both calls

will be heard in the speaker.

Audio First-Come First-Serve

When audio is pre-programmed for first-come first-serve, the audio from the

radio that receives a call first will be heard from the speaker for the duration

of the call. During this time, audio from the other mobile radios will be muted.
