S.O.S. Function
1
is equipped with a dedicated key for the fast
NGM Tango
forwarding of emergency calls (*).
This feature can be turned
on and off by selecting Menu > SOS > Activation (on/off).
In Menu > SOS > Call waiting time, you can decide to activate it
immediately or after long pressing it for 5 to 10 seconds.
In case of emergency, use this function to ask for help up to five
phone numbers, previously set in Menu > SOS > SOS numbers.
As soon as S. O. S. is enabled, the phone will start to emit a high
volume alarm tone (the alarm won't ring if you selected the "Call
now" option in waiting time). So, it will send an SOS message to
the SOS numbers set in Menu > SOS > SMS Recipients.
