Having Problems with radio for this reg, trying to put back old radio R770 keep putting code into radio but will not remember code. Now at the back of clock in the centre there is a hole, looking into it can see back of circuit board does a plugin or some kind of battery required for clock ? Or can someone advise me to what needed. Regards Bill. http://www.landyzone.co.uk/lz/images...es/biggrin.gif
