7 Troubleshooting notes
Malfunctions
Device cannot be switched on or
“cable”/“error” appears in the display
No reception after switching on the receiver,
signal LED is on
During operation: reception is interrupted,
signal LED is fluttering or remains on. The
audio signal is interfered.
Only with individual channels there are
frequent disturbances in form of interruptions
and whistleing in the audio signal. These
disturbances are not put down to effects of
the weather
No DMX channels can be received
The satellite television receiver connected to
the ADR receiver cannot receive all TV
channels
Possible causes
short-circuit in the LNB connection line
no signal available or the signal is too weak
receiving interferences due to effects of
the weather: heavy rain or snow, heavy
layer of clouds
receiving interferences due to the
irradiation of adjacent satellites (e.g. of the
satellite position 16° east)
the access to these channels is blocked
when you use a V/H LNB, the polarisation of
the satellite antenna is given if the ADR
receiver is on.
Elimination measures
switch off the device, disconnect the
LNB line, eliminate the short-circuit
check the installation (e.g. selected
LOF of the LNB), if necessary, redirect
the satellite antenna
use bigger satellite antenna
direct the satellite antenna in an
optimal way to ASTRA, then drive the
satellite antenna by approx. 0.5 to 1°
east. This reduces the irradiation
considerably.
check whether the smart card is
inserted in the card slot (observe the
notes for inserting the card). Switch
the device off and on again. Consult
the sales representative
switch off the ADR receiver or switch
it to standby mode.
