Operation
The call alert condition is cleared automatically from the radio by the iDEN Dual Channel
Card software to allow continued dispatching operation.
Setting the Call Mode (Group vs. Private)
Generic unspecified transmits (Xmit button, footswitch PTT, etc.) initiate a group or a
private call dependent on the currently selected call mode. The current call mode can be
changed by pressing the CHAN MODE button. This button toggles the mode between
GRP and PVT.
Specified transmits (Local Area, Wide Area, Private Call, Call Reply, etc.) still generate
the appropriate call type regardless of the current call mode.
Dependent on current call mode, the private ID or talkgroup of the last call initiated or
received is displayed in each channel window. Calls always display the appropriate private
ID or talkgroup during the duration of the call. In the idle state, the most recent private ID
or talkgroup transmitted, or received, displays according to the channels call mode.
Initiating a Group Call
The dispatcher can initiate a group call from the iDEN call submenu, from the main video
screen if programmed to do so, or from the Subscriber List window using the toolbar
buttons if enabled. To make a group call to the current talkgroup (displayed in the channel
box during idle periods), the dispatcher first highlights the channel (using the mouse
pointer and the left mouse button) that is used for the transmission, and then presses the
LOCAL AREA or WIDE AREA call button.
Alternatively, the TRANSMIT button on the audio panel, the XMIT screen button, or a
footswitch can be used to perform a local area group call when in GRP call mode (See
Setting the Call Mode (Group vs. Private) on page 97). Each of these buttons operates on
the selected (green-highlighted) channel. The type of call, LOCAL or WIDE AREA, is
determined by a switch selection on the iDEN Dual Channel Card.
For making calls to a different group, refer to Changing the Radio Talkgroup on page 100.
Initiating a Targeted Area Call
The dispatcher can initiate a targeted area call, i.e., a call to the current talkgroup in a
specified area, from the iDEN Call submenu, from the main video screen, if programmed
to do so, or from the Subscriber List window if enabled. To make the targeted area call the
dispatcher first selects the channel that is used for the transmission, enters the destination
area number (either by manual key entry or a Subscriber ID alias button), then click
TARGET AREA.
Initiating a Private Call
To make a private call, the dispatcher first selects the channel that is used for the
transmission, enters the destination radio ID (either by manual key entry or a Subscriber
ID alias button), then presses the PRIVATE CALL button.
