Other than its heavy rugged protection, the XP3 Sentinel has 3 risk management buttons in red, amber and green color. The green button can be used to indicate the start time or end time of your work shift. The amber key is used to request enhanced monitoring and tracking if you are going into a risky situation. The monitoring service may track you on a map and you will have to acknowledge your safety every ten minutes until the amber alert is deactivated. The dedicated red button gives you direct contact to monitoring centre, which will also include your GPS location to locate you. Your GPS location will be sent to the monitoring centre every 3 minutes until the phone battery is drained. On a full charge, the phone battery can send the GPS signal for at least 24 hours.
