Emergency operation
Emergency operation is available in TMO if the radio is in service. If your radio is operating in DMO
when you make the emergency call, the radio switches to TMO before making the emergency call. If
the radio cannot make the call in TMO, the radio automatically switches back 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). Silent Alarm calls cannot be activated when operating in Lone Worker or
Man Down modes.
When a Silent Alarm call is made, the radio displays the Home screen with the talkgroup associated
with call. During the call you may navigate away from the Home screen.
Live Microphone feature
Your radio may be customised with the Live Microphone feature. This feature allows you to
broadcast a call for assistance hands-free for a specified period of time and without having to press
the PTT button. The radio automatically cycles between transmit and receive communication during
a programmed period of time (seconds). Live Microphone is cancelled when the time expires or by
pressing the PTT button.
