Please read: If you feel the need to test your Spot unit in SOS / 911 mode, YOU must call Geos Alliance "FIRST" at (936) 582-3190. With both parties clearly understanding the time and location in which the Spot unit is to be tested AND Geos is not working a true emergency at that time. You can test your device. Please note the dispatchers name whom you talked to prior to testing. Give the dispatcher your direct contact phone number to be reached when the signal is received.
