The red emergency 911 button located underneath a rotating guard on the back of the Indigo Xplorer TS can be used at any time regardless of the tracking status (enabled or disabled) or the power status (on or off) of the device. When pressed, the emergency LEDimmediately 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/LED Emergency option. If the LCD screen is on during emergency activation, the black bar across the top of the screen turns red. The device sends three consecutive reports. After sending the first three emergency reports, the device reverts back to the default emergency time-between-reports (TBR) of two minutes.
