Dundee United striker Jon Daly and Lorraine Kelly backed the campaign
The countdown to the first digital television switchover in a Scottish city has officially begun.
Dundee residents will have their analogue TV signal switched off on 4 August.
The signal will be turned off in Perth, Angus and parts of Fife at the same time.
A 20-page guide, which includes tips on retuning Freeview equipment for the best signal, is being sent to every home affected by the change.
Among those taking part in the campaign to raise awareness about the change was Dundee United fan, TV presenter Lorraine Kelly and striker Jon Daly.
Speaking at an event at the city's Tannadice Park, Ms Kelly said: "Most sports fans have already gone digital, but not all viewers are prepared.
"With only three months to go until switchover, now is the time to get ready."
Studies suggest more than nine in 10 people in the area are using digital technology.
Until the switchover takes place on 4 August digital viewers are able to access Freeview channels from the area's main transmitter sites only, offering viewers about 40 channels.
Switchover will see more than 1,000 local relay transmitters upgraded to digital with relay transmitters broadcasting 15 Freeview channels, including BBC One, BBC Two, STV, Channel 4 and Five plus associated services like ITV2 and BBC Three.
Paul Hughes, Digital UK national manager for Scotland said: "Most people have already made the switch to digital, but we know some people may leave it until the last minute, or may need a little extra advice.
"We're urging anyone still watching analogue television to make the change now and to contact the help scheme if they're eligible for practical support."
