OSLO: Norway is set to become the first nation to start switching off its FM radio network next week, in a risky and unpopular leap to digital technology that will be closely watched by other countries considering whether to follow suit. 

Critics say the government is rushing the move and many people may miss warnings on emergencies that have until now been broadcast via the radio. Of particular concern are the 2 million cars on Norway's roads that are not equipped with Digital Audio Broadcasting (DAB) receivers, they say.
