People have until 18 June to switch their equipment
People on the Isle of Man have one month to make sure their televisions are ready for the digital switchover.
The island's Douglas transmitter will switch from an analogue to a digital signal on 18 June.
It means people who do not have a digital receiver after this date will not be able to watch television.
Digital UK, the authority responsible for promoting the switchover, has been running radio adverts and banners publicising the date.
"Digital switchover is about converting the TV you've already got to digital by means of a digital box, or a recorder or satellite TV," said spokeswoman Sarah-Jane Grey.
People can also check page 284 on Ceefax to check their existing aerial can receive a digital signal.
