Possible cause
The EXPLORER 540 is
unable to register on the
network, because the
GNSS position is
unknown.
The EXPLORER 540
cannot register on the
BGAN network.
The EXPLORER 540 is
currently controlled by
an external application,
e.g. LaunchPad or an AT
command interface.
There is no GNSS signal,
or the signal is weak.
If the EXPLORER 540 has
not been used recently
within the same location,
it can take up to 10
minutes to obtain the

Troubleshooting
Remedy
Make sure the view to the GNSS
satellites is not blocked.
To obtain position fix, the
EXPLORER 540 should be placed
flat on an even surface pointing
straight upwards, with a clear
view to as much of the sky as
possible. When the
EXPLORER 540 has obtained
position fix, you can point the
antenna towards the BGAN
satellite.
You can see position status in
the Dashboard of the web
interface (status section).
Check that your SIM card is valid
for communication on the BGAN
network.
Check your subscription with
the Airtime Provider.
If you want to use the built-in
web interface, stop the external
application and restart the
EXPLORER 540. Then open your
browser and access the web
interface.
Check the position status in the
web interface.
To help the EXPLORER 540

sky as possible.
When the EXPLORER 540 has
obtained position fix, you can
point the antenna towards the
