8 SPECIAL FUNCTIONS
8.1 Emergency call
There is a special orange button, at the top of the terminal, with which you can make
emergency calls.
The emergency calls may be:
- Group call (to a specific group in the phonebook, to the selected group or to another
special group not included in the user phonebook).
- Individual call (to a private TETRA address or to a telephone number, e.g. 112).
- A status message sent to an individual or group address.
The main characteristic of these calls is that they have maximum priority and interrupt any
other ongoing calls.
The emergency icon
appears when the call is active, whether you have initiated the call or
you are the recipient.
If the call is not connected, the terminal retries periodically until it connects, or until the action
is cancelled by pressing the emergency button again.
If the emergency call is a half-duplex voice call, an initial time can be programmed when the
terminal will transmit directly without having to press the PTT.
Besides, being able to send the standard emergency status (status code: 0) it can be
configured just before sending the programmed event to the emergency key.
