Emergency operation
Note:
In P25 Mutual Aid mode, emergency operation is not supported
and the Emergency button is disabled.
Emergency operation is available in TMO and DMO if the radio is in service.
If your radio is customised for Gateway and Repeater modes, it will make an
Alarm call in TMO. If it cannot make the call in TMO the radio will
automatically switch to DMO to make the call.
The red button on the top of your radio can be programmed to initiate an
Alarm call at any time when your radio is in operation. This button is known
as the
Emergency Button
.
Your radio may be customised to perform one or more of the following:
Initiate an Alarm call set up to one or more pre-defined users (typically to
your dispatcher and other members of your talkgroup) and/or;
Send an Emergency Status message to an individual, the dispatcher or a
talkgroup and/or;
Send a position report (GPS dependent).
If you are working in RF sensitive areas and have enabled Transmit Inhibit,
prohibiting radio transmission, initiating an Alarm call will override the
Transmit Inhibit feature and the Alarm call will be transmitted.
Your service provider or organisation can provide information on how your
radio is customised for Alarm calls and how to operate your radio in
emergency situations. If you are working in a sensitive environment your
radio may be customised for Silent Alarm calls where audible and display
alerts are disabled, or your radio may be customised for Live Microphone that
allows you to call for assistance hands-free without pressing the PTT button.
Silent Alarm Call
If you are working in sensitive environments where the audible and display
alerts associated with an Alarm call are inappropriate, your radio can be
customised to make a Silent Alarm call (without acoustic or screen alerts).
