People in the East Midlands who watch TV on freeview will need to retune their TV equipment today.
It is because local airwaves are being cleared to allow for faster mobile broadband. Around 815,000 homes in Waltham, Leicester, Derby, Nottingham and Melton Mowbray will be affected by the work at the main Waltham transmitter, which is expected to be completed by 6am this morning and many viewers can retune at any point after this.
Technical changes at the Waltham transmitter group will free up frequencies for the future introduction of fourth-generation mobile services.
Services at some local relay transmitters may be off-air until mid afternoon.
Once these start again, anyone missing channels should retune their TV or digital box to get them back.
Some TV services may have been subject to disruption from midnight as channels including BBC One, BBC Two, ITV, Channel 4 and Channel 5 moved to new frequencies.
Viewers who can receive signals from more than one TV region may need to manually retune to select their preferred services.
Between now and the end of 2013, similar upgrades will be made at a number of transmitters across the UK to prepare for 4G†.
How to retune Freeview equipment:
- 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
