the web interface.
To help the EXPLORER 500 obtain GPS
fix, it 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 500 has obtained
GPS fix, you can point the antenna
towards the BGAN satellite.
Make sure the EXPLORER 500 has a
clear view to the satellite. Be aware that
window glass, trees, or even rain may
reduce the signal level.
Check that the antenna is pointed
according to the position data.
Adjust the position to the highest
possible signal strength.
