Well you need the manual , and you need to understand what defaulting does and what the alarm does
It's better to scrap it tho and if you intend to try and make "something work" get a scantronic 9651 and it will be easier to setup and you can work your way through the faults over the 6minths to few years if that's what it takes
Sometimes it may work to an extent but you can never realised the problems , you will have to get or ask for help on each problem that occurs
