If you receive your television signal via an aerial you may need to retune your television or set-top box today after changes were made to channel frequencies.
Technical changes at the Mendip and Stockland Hill transmitter groups will free frequencies for future fourth generation (4G) mobile services.
Homes in Somerset, parts of Devon and Dorset are affected.
TV services will be subject to disruption from early this morning as channels including BBC One, ITV, Channel 4, Channel 5, Film4 and Yesterday are moved to new frequencies.
Services may be off-air until late afternoon. Once these resume, anyone missing channels should retune their TV or digital box to get them back.
Television services received via satellite are unaffected.
How to retune your television or set-top box:
- Make sure your Freeview TV or box is on. If you have a Freeview TV, ensure it is in digital mode by pressing the DTV or digital button on your remote. Then press ‘menu’.
- Select the ‘set up’ or ‘installation’ option. If you see picture icons, select the tool box, satellite dish or spanner.
- If you are prompted for a code, try 0000 or 1234.
- Select the full retune option. This is sometimes called ‘first time installation’, ‘factory reset’, ‘default settings’ or ‘shipping conditions’. Selecting ‘channel update’ or ‘add channels’ may not always fully clear old channels and enable new ones to be found.
- Press ‘OK’ if you are prompted to delete all your channels; don’t worry, this is normal.
- Channels will automatically be installed. This may take a few minutes and your equipment may shut down and restart.
