TETRA Emergency Calls
Triggering a TETRA emergency call starts a group call of a particular priority. Use this
function only when you are in an emergency situation.
Special features
So long as the radio set is logged into the personal emergency signal centre, trigge-
ring the emergency call will generate a "personal alarm" and transmit it to the perso-
nal emergency signal centre. A TETRA emergency call is only possible when the
radio set has not logged into the personal emergency signal centre.
During an active TETRA emergency call connection, the radio set works with the fol-
lowing restrictions:
The scan function is deactivated. Group monitoring is not carried out.
Individual calls cannot be received.
