The switchover to digital TV begins Tayside and Fife on Wednesday, with a special warning made for some Fife residents.
Although most of Fife won’t lose the analogue signal until later this year or next, some residents are to be affected by change to the Angus transmitter group in the STV North region, due to start on August 4.
There are five transmitter groups in the STV Central TV region that will switch over at different times, starting on October 13.
When you switch depends on which transmitter group you are watching.
To find out which transmitter you are likely to be watching at your address and the switchover dates and channels available, visit the switchover website.
For more advice about how Fife is affected, call the contact centre on 08456 505050.
Opening hours are 8am on 7pm Monday to Friday and 10am to 4pm Saturdays, plus extended hours on switchover dates.
