4.4. SOS Alert
• Press and hold the SOS Button for 2 seconds, the CAREU P2 will beep 4
times. Within 10 seconds time, if the user presses and holds the Geo-fencing
button for 2 seconds, CAREU P2 will make a long beep once and cancels the
SOS alert event. If no cancellation action takes place within 10 seconds time,
the SOS event then becomes valid and proceeds to alert actions.
• As soon as the SOS Button is pressed, the CAREU P2 will automatically
power on and executes the “SOS” process even if the CAREU P2 is prevously
powered off.
• Geo-fencing is disabled when “SOS” event is active.
Note: When SOS alert event is active, Power Button is disabled immediately. The
user must cancel the SOS event by pressing the Geo-fencing button first
before CAREU P2 is able to power off normally.
