Drayton RF2 - problems re-resetting

[Kev1965]

Hi, I have a Drayton RF2 wireless thermostat, and I am trying to re-set after a battery change. ( I have no manual, by the way).
The screen shows a flashing battery, 34c, and the time and whenever I change it returns to this. How do I get rid of the flashing battery ( it shows a + by the way) and change the 34c? Please help, i'm freezing and the boiler is in the loft.
