• The Signal LED flashes green once every three seconds when the inReach is sending a message of any type. The LED will stop flashing when the message is sent, unless the inReach is tracking in standalone mode. When tracking in standalone mode, the Signal LED flashes continuously to indicate the status of the GPS satellites.

The Signal LED will flash red until the message is successfully transmitted or cancelled. If the LED is flashing red, try moving to a new location to get a better view of the satellites.
