Hi,
We are having a couple of problems. Firstly we have a blind that even after installing new batteries will raise about 3/4 up the window, and then stop and flash red/green 3 times. The only place I can find in the manual where it indicates this should happen is when the blind has new batteries fitted.
The other problem I have with a couple of the blinds in the house is that we are getting around 9 months battery life from them, when we have Duracell or Energiser D size batteries fitted to the blinds, they are longer/wider blinds with 8 batteries in the blind, but the life is significantly less than we expected and we are onto a third set of batteries after 18 months, and replacing 8 batteries is not the cheapest exercise.
