The London TV Region switches to digital in two stages on 4th April and 18th April.
If you have Freeview, then you will need to re-tune on both switchover dates.
For switchover information visit www.digitaluk.co.uk or call the UK advice line on 08456 50 50 50.

For re-tune advice see your Grundig User Guide and the FAQs on this site or visit www.digitaluk.co.uk/retuning.
