[Sterling 10 alarm with remote keypad RINS 451-3]

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
