Around 20,000 homes in Tayside and north Fife are still not prepared for the digital switchover a month before the analogue signal in the area is switched off.
The Angus transmitter group will start the switch to digital television on August 4.
In the first phase BBC Two will go off air to be replaced by an array of the corporation’s digital broadcast channels.
On August 18 all other analogue television channels will be scrapped and additional digital services added.
A spokeswoman for Digital UK said, “Latest research indicates that most viewers in the area are well prepared, with nine out of 10 households already having made the switch to digital TV on their main set.
“Those still watching in analogue are now being advised to get ready for switchover.
“Viewers watching via Freeview will need to retune their TV or digital box at both stages of switchover satellite and cable TV services are not affected.”
Many of those facing the loss of their TV signal are the elderly and infirm, who tend to struggle with the technologies.
The Digital UK spokeswoman said there was help available for those having difficulties with the switchover process.
“People aged 75 and over, eligible for certain disability benefits, registered blind or partially sighted or living in care homes are entitled to practical help to switch to digital TV from the BBC-run switchover help scheme.”
She added, “Everyone eligible will be contacted directly by the help scheme before switchover.
“Digital UK and the switchover help scheme also work with local charities to provide information, advice and support to those who may need some extra help managing the switchover process themselves, or opting in to the help scheme if they are eligible.”
