The red emergency 911 button is located underneath a rotating guard in the back of the Indigo Xplorer. It can be used at anytime regardless of the tracking status (enabled or disabled) or the power status (on or off) of the device. When pressed, the emergency LED immediately turns solid green to indicate that the device is in emergency mode. The LED can be deactivated to extend the battery life by using the Settings/LED/Power LED emergency option. If the LCD screen is on during emergency activation, the blue bars across the top and bottom of the screen turn red. The device sends three consecutive reports as quickly as possible. After sending the first three emergency reports, the device reverts back to the default emergency time-between-reports (TBR) of two minutes.
