BETWEEN Autumn this year and 2012, the analogue signal (the one which allows you to watch BBC1, ITV1, Channel 4 and Channel 5 only through an aerial) will be switched off.

This means that any TV that is not converted to digital when the switchover takes place will no longer receive TV programmes.

You can get information about the switchover from Digital UK, an organisation set up by the public broadcasters to inform the public about the move. Their website is www.digitaluk.co.uk You will need to make sure that all the TV's in your house will need to be able to receive a digital signal.

Top tips for the big switch-off

* You may not need to replace your existing TV unless you want to, but you will need a digital box (via aerial, satellite dish or cable).

* If you are thinking of upgrading your current set, you may want to consider getting a TV with a digital box built in and look for the digital "tick" logo.

* Don't forget about your video recorder too. If you use a VCR or a DVD recorder for recording, then you will need to adapt it with a digital box or replace it with a digital recorder that has a built in digital box, sometimes called a PVR.

* Look for the digital "tick" logo which certifies products and services that are designed to keep working after the switchover.

* Stores displaying "Get Set For Digital" sign will stock certified products.

* If you plan to purchase a new TV, then shop around for the television you plan on buying before handing over any money, as some deals may not be so appealing when the small print is revealed.

* Consider how much you want to spend and if the equipment needs to be compatible with any other audio-visual items you already have.

* When buying a television that's over £100, it's worth thinking about putting it on your credit card. That way you've got added protection in case things go wrong.

* You may be given a guarantee or warranty when you buy any electrical equipment like a TV or stereo. Make sure you read the small print; don't presume it will cover all eventualities. And remember when your guarantee expires, your rights don't expire with it.

* Be aware of high-pressure selling of extended warranties. Ask yourself, do I really need this extra cover? Remember - you have your statutory rights and the manufacturer may offer a guarantee anyway. If you decide you require further cover, why not get a quote from an insurance broker instead?

* If you need to make a complaint, be persistent. If a shop isn't being helpful, put it in writing to their head office, and make sure you list all the details and dates and keep a copy for yourself.

* Remember that when ordering goods over the internet, if no time limit for delivery is given, you should still receive the goods within 30 days. For more clear, practical consumer advice, call Consumer Direct on 08454 04 05 06 or visit www.consumerdirect.gov.uk.
