Optima XM6 .Replaced battery recently. Since then the keyboard sounds have gone very quiet, and similar when arming system and entering the building. How do i increase the volume .
When i have the cover off the alarm as when i fitted the new battery the sounder was as before, but so quiet when cover is refitted. Any advice much appreciated

I doubt the volume can be changed. Check there's nothing obstructing the sounder in the panel.
