My RF-7800B-DU does not seem to turn on when power is
applied.
Check if the 'Auto Power On' feature is enabled on
the Web interface 'Setup' page.
The 'Auto Power On' setting might be disabled on
your terminal. Use the switch to power off the
terminal and power it back on. Check the 'Auto
Power On' feature setting via the Web interface.
When the 'Auto Power On' feature is enabled, the
terminal will automatically power on when power
is applied to the unit and the power switch is not in
the OFF position. This feature allows for automatic
reboot of the terminal following an unexpected
power failure.
The BGAN terminal was online, but has since been placed

 Has the view of the satellite become obstructed?
Restore a clear line of sight between the terminal
and the satellite. The connection will automatically
be restored if the interruption was less than one
hour.
The BGAN terminal was online, but has since been placed

 Was there any data sent over the connection for 12
hours?
The BGAN system will automatically deactivate a
context that has not sent any data for 12 hours.
Manually reactivate the PDP Context.
If desired, enable the '24/7 PDP Context Keep
Alive' feature on the 'Setup' page of the Web
interface to keep unused connections active longer
than 12 hours.

 Did you reach the data limit for your BGAN
subscription?
To limit BGAN expenses, USIM cards can be
commissioned to have a daily/weekly/monthly
traffic or monetary limit.
Contact your USIM administrator to obtain more
air-time. Check with your BGAN Service Provider
to determine if this was the cause.
