I have been trying to learn the Comdial Executech XE NO308 system. I reset the system to factory defaults and all seemed to be ok. When I rang in to the system, all phones rang and their LED's lit. Today, I configured Line 1 to appear on key A1 as a test. The default is key B1. Now that I have done this, the other stations no longer ring for an incoming call. I tried to reconfigure the line appearance back to B1 but it will not take the program change. Does this sound correct? My only choice now is to reset the system back to facotry defaults (not a big deal). Does anyone have any ideas on this one? Is there a way to clear the programming on a soft-key?

Thanks
