Broadcast calls
Sometimes it may be necessary for your Dispatcher to make a high-priority broadcast (also known
as a Site Wide Call) to all network users. These calls take priority over any lower priority on-going
calls, and you cannot respond to them: pressing the PTT key has no effect during a broadcast call.
During a broadcast call the display changes to ‘Broadcast Call’ and the Broadcast Call icon is
displayed.
Quick Calls
A Quick Call allows you to request help or information in a non-emergency situation.
To initiate a Quick Call
1. Press a pre-configured soft key.
2. Press the PTT to transmit.
Depending on the configuration this causes all or some of the following to happen:
if your radio is in Smart Call Mode it reverts to Group or Individual Mode (see Smart Calls
below).
your radio sets up a voice call to a programmed recipient which can be individual or talkgroup
your radio sends up to two Status messages
your radio sends a position report
Quick Calls cannot be made from a radio which is making or receiving an emergency call or if your
radio is in Transmit Inhibit mode. See Emergency operation on page25 and Transmit Inhibit
on page77.
Smart Calls
A Smart Call is a high priority group or broadcast call to a specific talkgroup. This can be useful, for
example, where you need to make an announcement to everyone in the vicinity of an incident, not
just those in your selected talkgroup.
The radio supports two separate Smart Call Modes (A and B) associated special folders Smart
Call 1 and Smart Call 2 respectively. Each Smart Call Folder can be pre-configured with up to 75
talkgroups.
You initiate a Smart Call by switching to Smart Call mode, then you press the PTT to transmit to a
chosen talkgroup in the Smart Call Folder.
Broadcast calls cannot be made from a radio which is in DMO. Attempting to make a Smart Call in
DMO initiates a group call to the attached talkgroup.
