The EXPLORER 710
cannot obtain its
position from the GNSS
system. There is no GNSS signal, or
the signal is weak.
If the EXPLORER 710 has not
been used recently within the
same location, it can take up
to 10 minutes to obtain the
position. Check the GNSS status in the
display or the web interface.
To help the EXPLORER 710 obtain
position 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 710 has
obtained position fix, you can
point the antenna towards the
BGAN satellite.
No signal or weak signal
from the BGAN satellite. The view to the satellite is
blocked. Make sure the EXPLORER 710 has
a clear view to the satellite. Be
aware that window glass may
reduce the signal level.
The antenna is pointed in the
wrong direction. Check that the antenna is pointed
according to the position data.
Adjust the position to the highest
possible signal strength.
Connection to the
Internet cannot be
established. The signal strength is too low. Check that the antenna is pointed
according to the position data.
Adjust the position to the highest
signal strength you can obtain.
As a rule of thumb, you should
have a a signal strength of
45 dBHz or more to be able to
make a call or data session.
