Possible cause
There is a problem with
the satellite signal .
Something is between
the remote control and
your box .
The batteries are flat or
inserted the wrong way
round .
The video resolution that
is output from your box's
HDMI connector may
not be suitable for your
HD TV .
If you have an HD TV, and
you connect a separate
audio system to the
SPDIF connector on
your box, you may have
to adjust the audio delay
setting .
Suggested solution
Check that the lead from your satellite dish is
correctly connected to your box .*
Check that your satellite dish and LNB(s) are
correctly set up and directed towards the correct
satellite(s) (see page 11) .
Check that nothing is blocking your satellite dish,
for example a tree or high building .
There may be a temporary problem with the
reception, caused, for example, by bad weather;
try again later . If adverse weather conditions
cause your dish and/or LNB(s) to move, you
may need to re-adjust them (see the information
supplied with this equipment) .
Make sure you point your remote control directly
at your box and that nothing is between it and
your box . The indicator light on your box's front
panel should flash each time you press a remote
control button .
Check the batteries and replace them if
necessary .
Change the video resolution to obtain improved
picture quality (see page 36) .
Also check your HD TV's picture settings .
Change the audio delay setting until the audio and
video are in sync (see page 37) .
Call customer service for advice .
Follow the instructions on 'Inserting your smart
card' on page 10 .
