Hi all, I hope you can help me, I have the above alarm system that I had to install a new bellbox on. When powering up the main unit it lost its settings, I have recovered the system using the factory default engineer code, however I now need to program the four preset arming options And I dont have a guide on how to do it, the manuals I have found online are all for older versions of the keypad. the keypad i have can be found here http://alarmwise.co.uk/special_offer_sterling10.html
