Picture regularly breaks up on
some channels, “No Signal”
message is displayed.
Check “Signal Condition”. If “Signal Quality” or “Signal Strength” are displayed
in red or constantly changing, check aerial. If problem persists consult your
local TV aerial installer.
Check that the aerial and antenna cable are designed for DVB.
Use the supplied RF coaxial cable shown in STEP 2, Basic Connection.
Interference (known as impulse noise) from household appliances such as light
switches, fridges, etc. may cause picture break up and/or audio distortion. Use a high
quality quad shielded coaxial cable fly lead between this unit and antenna wall socket to
minimise impulse noise pickup. If problem persists consult your local TV aerial installer.
When “No Signal” message is displayed, check aerial connection.
Adjust the aerial reception with “DVB Manual Tuning”.
Perform “Auto-Setup Restart” in the Setup menu.

Picture very infrequently breaks up
on some or all channels.
Electrical atmospheric interference caused by local or distant lighting storms
or heavy rain with wind in “leafy” locations may cause pictures to break up and
audio to mute or distort momentarily.
Impulse noise interference from an infrequently used electrical appliance, or a
passing vehicle or lawn mower with a “noisy” ignition system.
