play 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-pro-

grammed 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-pro-

grammed) on the control unit. Also, a button may be pre-programmed to ro-

tate 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 se-

lected if the radio select button is pressed when radio #1 was selected.

Radios in the multiple radio operation share the control unit display. Pre-pro-

gramming the radios determines what the control unit displays. There are

two modes of display: alternating radio display or first come first serve dis-

play. See also the following paragraph on Audio Modes.

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

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

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

radios from being heard for the duration of the call or hang time (if enabled).

This mode corresponds with the first come first serve audio mode (see fol-

lowing 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.
