OK, I do not know which model of radio you have but if it is similar to DMR105, try doing a "factory reset".
It is also possible that one of the following has happened: The station you were listening to had a break in transmission. - Try another station. You have lost the radio signal. - Try another station. Your battery has run flat. Change battery/power source.
