The East Midlands region is to begin the switch to digital television on Wednesday 30 March.
As switchover begins at the Nottingham transmitter, with analogue BBC Two permanently turned off, changes will also be made at the Waltham transmitter serving much of the East Midlands, where switchover takes place later in August.
Digital UK is advising Freeview, BT Vision and Top Up TV viewers to retune any time after 0600 on 30 March to regain access to channels that will have disappeared.
Around 880,000 households across the East Midlands are served by the Nottingham and Waltham transmitters, including areas such as Stamford, Leicester, Derby and Matlock.
Waltham viewers will need to retune on 30 March and again on 13 April, 17 August, 31 August and 12 October 2011.
