intermittent black screens.
Your receiver may be
experiencing signal loss due to
something blocking your dish’s
view of the sky, the dish being
mis-aligned, or weather.
• Make sure that the satellite dish has a
clear line of sight to the satellite.
• Check whether branches or leaves
have grown into the line of sight.
• Make sure that the satellite dish is
aimed at the satellite. Check the
strength of the signal using the Point
Dish screen, as described on
page 101. Consult your installer to re-
aim the dish, if necessary, to obtain
the maximum possible signal
strength.
• Note the local weather conditions.
Heavy rain, snow, or cloud cover may
be interfering with transmission of the
satellite signal. Remove any snow or
other debris which may have
collected on the satellite dish.
