how do i change the battery in my 9751 control panel?

if you do have the engineering code,key it in,you can then remove the cover of the end station,WARNING there are mains voltage present,carefully remove the old battery,replace new one red lead to red terminal,black lead to black terminal on battery,replace the cover,key in 99 enter,thats it,do not touch any other component in end station,BE CAREFUL

Or if you do have full controll of the system ie engineering code as gts has pointed out,then post back.

Iam sure one of the pros will guide you through the procedure.

get some one in,it may be prog engineer reset,so if you open it up,you will not be able to use it again without engineer code,
