2.4 Emergency (SOS) Button
In order to initiate an emergency or SOS notification, press and hold the SOS button
for 3 seconds or until you feel the MD4 vibrate (this is a default setting that can be
customized). At that point the MD4 will do the following:
1. Connect to the GPS network and retrieve an updated location (if the GPS
network is not available, it may use the last known location),
2. Connect to the cellular network to send the SOS notification via email, text
message or both, and
3. Begin to call the SOS contact numbers set for the MD4 (ask your service
provider for assistance as needed).
Setup Multiple SOS Numbers: Up to 4 SOS numbers can be set and called in
