Troubleshooting
Problems after installation
Not every picture or sound problem is caused by a defect in your DTR. Leads having been
accidentally pulled out or worn out batteries in the remote control can also cause impairment.
If your unit does something unexpected while you are using it, please unplug it, wait a few seconds,
plug it in again, then wait for the lights on your DTR to change to solid
RED
or
GREEN
. If this fails
to solve the problem or the following measures do not bring about satisfactory results, please consult
an authorised dealer.

Reception problems
When you purchased your DTR, your dealer should have checked your postcode to ensure that you
can receive digital terrestrial TV. If you wish to check this yourself, please look on the internet
websites:-
www.freeview.co.uk
or
www.digitaluk.co.uk
Once you have established that your area should be able to receive digital terrestrial TV, there are
a few reasons why you may be experiencing problems.
•
Your current aerial and cabling may not be able to receive all the digital channels
due to its age and condition. Now is the time to renew them. We recommend the use
of CAI “Benchmarked” aerials. Look for the logo.
Always use good quality, double screened aerial cable. e.g. CT
100
coaxial cable.
•
In your location the digital channels may be transmitted on different frequencies to your existing
analogue signals and you may need a different type of aerial to receive them. Check the ‘group’
of your aerial, you may need a ‘wideband’ one.
•
The new digital channels may be transmitted from a new transmitter and if this is the case the
aerial would have to be re-aligned. Alternatively, add a second aerial to your system.
•
If you need to use a mast-head amplifier, make sure that it is a digitally compatible one and that
it is as close to the aerial as possible.
•
In some blocks of flats, filters may be in use that will interfere with digital signals. Consult with
your landlord if you have difficulties.
•
Indoor or window mounted aerials are not recommended, except in areas where the signal is
extremely strong.
•
Your aerial could be too high. Try adjusting the height of the aerial to avoid picking up unwanted
signals from other transmitters.
•
If you live near a road, the passing traffic may cause problems. Try pointing the aerial at an
upward angle over the road, this helps reduce engine interference picked up by the aerial.
•
If you get periodic picture losses, this could be due to electrical interference picked up in your
house. This could be from a central heating thermostat, a fridge/freezer, or any other item with
a motor. Try switching these appliances off temporarily to establish what is causing the problem.
Then replace the problem item.
•
If your aerial comes into your room via an aerial connection point (socket), replace it with a good
quality shielded one. This will help prevent electrical noise entering your aerial.
