1800 Registration for
data failed
The system has not yet been
allowed to register for data
services (Packet Switched).
If the problem persists,
contact your airtime
provider.
2900 Network failed
authentication
The system does not accept
the network as a valid BGAN
network.
Restart the system.
If the problem persists,
contact your distributor.
3900 Air link error Error condition in DSP which
modulates and demodulates
BGAN signal.
Reboot the terminal.
Contact your distributor if
the problem persists.
8030 Antenna could not
enter main
application mode
Antenna failed to start up
normally.
Reboot the terminal.
Contact your distributor if
the problem persists.
8035 Antenna connection
lost. Power off
terminal and check
antenna cable.
There was an error
communicating with the
antenna.
Reboot the terminal. Contact
your distributor if the
problem persists.
8049 Data rate reduction
due to high
temperature
The bit rate of the data
channel is reduced because
the temperature is too high.
Move the terminal to a
cooler location.
8056 SIM rejected The type of USIM card
inserted in the terminal is not
correct for your terminal.
Make sure you have the
correct type of USIM card.
For example, an USIM card
for a land mobile system will
not work for a maritime
system and vice versa.
8098 Measured DC
resistance in
antenna cable is
too high
The DC resistance in the
antenna cable is too high.
May be caused by corrosion
or poor connections.
Ensure antenna cable
connector has no corrosion.
Ensure all antenna cable
connectors are tightly
screwed together.
921E Antenna input
voltage outside
range
Voltage to HPA in antenna
out of range.
Check voltage to terminal is
in range 10 - 32 V DC.
Check that antenna cable
connections are sufficiently
tightened.
9220 Antenna temperature
above critical
limit
Antenna temperature too
high, might affect
performance.
If possible, move the
antenna to a cooler location.
