Well...I'm not sure what exactly is going on. I went ahead and opened it up and took a can of compressed air to it, put it back together and same thing. But, I did find out that with the housings off I could get it into programming mode???
After a few tries I was able to get it to stay in programming mode long enough to add the new call tones, so at least I got that done, but still not sure why its not working properly?
Anyway, thanks for the help.
