of your terminal.
Your terminal may be configured with one of the following:
•   Emergency Group Call
The terminal will enter Emergency Mode when you press 
and hold the Emergency button.
• The required time you need to press the Emergency button is set by 
default to 0.5 seconds. The time can be configured by your Service Pro-
vider.
• Pressing the Emergency button even if Transmit Inhibit is activated
