New channels are launched on Freeview from time to time along with other updates to the service. So it pays to retune your digital box or TV every couple of months to make sure you are up to date. Many digital boxes and TVs now prompt you to retune when a new service launches but if yours doesn’t it will have to be retuned manually. The process is straightforward but varies slightly between boxes from different manufacturers.
Press menu on your box or TV remote control.
Now select set-up, installation, update or similar option. If you’re asked for a password the default code is 1234 or 0000.
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.
