Clearing an Alarm call
You can only clear an Alarm call that you have initiated.
To cancel the Alarm call, press the Clear context key.
Warning: Depending on which network is being used, if the
TETRA Alarm call is a group call, then although both of the
TETRA Alarm call exit functions will clear the TETRA Alarm call
on the call originator’s radio, it will not remove the alarm from
the system. It should also be noted that those radios alerted to the
emergency may, depending upon the infrastructure configuration,
remain in the TETRA Alarm call condition until the dispatcher
clears the call from the system.
When the Alarm call is cancelled, your radio returns to the talkgroup that
was selected before the call was initiated.
Power on Alarm call
If your radio is powered off, press and hold (3 seconds) the Emergency
button to power on and initiate an Alarm call. Any customised Welcome
screen is not displayed during power on. If your radio is customised for
PIN entry, you will need to enter your PIN before the alarm call is
initiated. It may take several seconds for the radio to complete its power
on process before initiating the Alarm call.
