When you ‘retune’, your Freeview TV or box scans for new channels and any changes to existing channels. It’s a good idea to retune regularly – perhaps once a month – to make sure that you are receiving all the channels available and getting the best out of Freeview in your area. Step 1 Press menu on your box or TV remote control. Step 2 Now select set-up, installation, update or similar option. If you’re asked for a password the default code is 1234 or 0000. Step 3 Now select the ‘first time installation’ option (sometimes called ‘factory reset’, ‘full retune’ or ‘default settings’). Press ‘OK’ if your equipment asks if it is OK to delete existing channels. This will clear your existing settings and find the new channel line-up. If prompted then save the channels that are found. You may find that channel favourites and scheduled recordings are also deleted so check and reset these. If you are still encountering problems check the instructions for your product on the product manuals section. Your equipment may automatically retune, or you may need to do it manually. You will find more details in your user manual, or you may be able to follow on-screen instructions. Related content: Other retuning FAQs I have lost the manual for my TV or digital box.
