Sepura SC20 series Quick Start Guide

To cancel the Alarm call, press the Call Clear key, the Clear context key
or the Cancel/Home key. Alternatively, your radio may be customised to
use the Emergency button to cancel the Alarm call.
To cancel the Alarm call, press
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. 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. It may take several seconds for
the radio to complete its power on process before initiating the Alarm call.
