Hello, Have heard this before, from people who own the units but are not on the list. Wonder if something like what is used to clean a camera lance, not liquid, but the air in a spray bottle might do the trick. I use that on my dials for my mixer, the stereo, and it works fine. I would ask Pam or some one else at APH before I use the cleaner.

I suspect after years of use, my keypad is either dirty or just wearing out. Would be curious if others have had this problem and what they are doing about it. Don
