Troubleshooting

Digital terrestrial signals blocking/freezing and/or loss of digital picture and sound can be caused by insufficient
digital signal and carrier to noise ratio.
Similarly blocking and even a completely blank screen with no sound can result if the input signal to the set top box
is too high. The digital cliff refers to the rapid change from the picture and sound being perfect, to disappearing
altogether.

No picture:
Check all connections from aerial to TV.
Poor picture:
Check all connections from aerial to TV.
Check aerial is properly aligned to the correct transmitter.
If the aerial has been loft mounted try mounting outside.
Make sure new digital coax cable has been used throughout the installation.
Check the transmitter signal is not obstructed by nearby trees or buildings.
If in a very weak signal area or for long cable runs, installing a masthead amplifier will improve the signal.
If in a strong signal area the signal strength may need to be reduced by fitting an attenuator.
Intermittent Picture:
Make sure all RF cable to connector joints are tight (both inner and outer) including all flyleads
and surface outlet connections.
To Prevent Overheating
The recommended clearances and other precautions
given in the installation section of these instructions
must be observed to prevent overheating.
In addition, the amplifier should not be fixed where it is
likely to become smothered by curtains or other fabrics,
etc., or other thermal insulation materials in a roof space
or similar building void. The unit should not be left
resting on a carpet.
Cable Installation
Do not install cable -
Closer than 50mm to mains or
telephone wiring.
Under carpets in areas likely to be walked on regularly.
With sharp bends at corners
.
Other Precautions
Apart from the aerial and cable all other parts of the kit
are not waterproof and are for indoor use only.
They must not be fixed where they could be exposed to
dripping or splashing water. Objects containing liquids
should not be placed on or near the appliance.
To prevent risk of fire, no object with a naked flame
should be placed on or near the appliances or the wiring
to them.
