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.

•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.
