General Safety Precautions
Do not undertake work outdoors at height unless you are
competent in the use of ladders and other access equipment.
Always use correct equipment, observe appropriate safety
precautions and follow manufacturers instructions. If in doubt
consult a professional installer.
Before starting installation check structure is sound and check for
hidden wiring or plumbing.
When working on an installation outside, beware of overhead power lines.
Observe safe working practices, tread carefully on roofs and ensure
adequate lighting is available if working in loft or roof space.
Before making any connections switch electricity off at the mains.
To avoid injury always route cables or wiring carefully. Ensure cable
is correctly routed before xing into position, taking care not to
overtighten cable clips.
This kit contains small parts - keep them out of reach of children.
After installation make regular maintenance checks for wear and tear.

Troubleshooting
No picture:
Check all connections from aerial to TV.
Poor picture:
Check all the 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.

Installation
For best results the aerial should be mounted on an outdoor aerial
mast and pointed in the direction of the nearest transmitter*
making sure it is in a position where the transmitter signal
will not be obstructed by nearby trees and buildings.
If you are in any doubt about the direction in which the aerial
should be pointing or the orientation of the aerial (horizontal
for main transmitter, vertical for relay transmitter) check your
neighbours’ aerials.
