The orange LED reflects the
mobile status and also whether
the device is switching on.

This LED blinks green and
indicates the status of the GNSS
receiver.
Off: GNSS is not switched on.
Blinking once: Position
acquisition.
Blinking twice: 2D-Fix (no valid

After start up as well as after a
phase without GNSS reception
the device only accepts 3D
GNSS positions.
This ensures, that 2D positions
reports with serious deviations
from the real position are not
reported to the control center.
After a while, 2D position
reports are accepted because
the GPS receiver had enough
time to evaluate the signal
quality of all available satellites.
A very short flash every 2
seconds indicates that the
device is in sleep mode.
