Quick Start Guide

Emergency operation
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.
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.
