Table 2 Troubleshooting guide
AC power beyond the limits of allowed
values
Check AC cable.
Replace a cable.
Check AC cables.
Contact your nearest dealer or service center for
advanced support.
ERROR indicator lights
constantly after
power on.
Router can’t start the software
Press RESET button on the rear panel of the router.
Contact your nearest dealer or service center for
advanced support.
Router restarts every
3-5 seconds.
Short-circuit in transmit cable
Disconnect and check Tx cable
Reset software to factory defaults
No reception from
the satellite (indicator
LOCK is off, single
flashes of ERROR
indicator)
Check Rx frequency and symbol rate.
Check Rx cable and make sure that its connectors
are properly connected to the LNB and the router.
Check if LNB power is switched on
Disconnect Rx IF cable from LNB and make sure that
12-18 VDC is available on the connector.
Check Rx level in the statistic of the demodulator.
No carrier on the satellite or its level is
insufficient.
Verify availability of the carrier and its level with
spectrum analyzer.
Contact Hub administrator and investigate if the
carrier is properly transmitting and local weather
conditions not attenuate the signal.
Measure carrier signal to noise level with a
spectrum analyzer.
Verify if antenna is properly pointed to the satellite
and there no obstacles in the direction to the
satellite.
Check the integrity of the film of antenna’s feed
horn and absence of moisture in it.
Replace LNB to the spare one
High rate of errors of
Rx path (LOCK
indicator is not
lighting constantly)
The quality of reception may temporary decrease
during intensive rainfall, for, thunderstorm
cloudiness.
Check if there is no snow or ice on the antenna
surface and on the feed horn.
Low signal to noise level
Check C/N in demodulator’s statistics.
Verify if antenna is properly pointed to the satellite
and there no obstacles in the direction to the
satellite.
Check the integrity of the film of antenna’s feed
horn and absence of moisture in it.
Low Rx carrier level
Interferences
Check Eb/No in demodulator’s statistics.
Contact Hub administrator and investigate if the
carrier is properly transmitting and local weather
conditions not attenuate the signal
Station is not

(Reception is normal:
Check Tx frequency and symbol rate of the
modulator. Make sure that transmission is enabled
