you can do it,just turn mains power off first but take note,the panel may be set for engineer reset that means you have to have the engineering code,open the panel after you have turned mains power off replace the battery close the panel key in your pin number hopefully it will reset if not try key in 07890
if that not work get back to us just be carefull ,ok ?
