I picked up a new customer today that lost bits and pieces of the programming after a power outage. I was able to get them back and running except for one item. They have an IVX72eIIFSIII.
I have the Day/Night Button on X100 just like before. The screen shows that it is in Day Mode. But when you press the button, it says "You can not use this feature from this phone". That's a first for me. I removed the button and replaced it twice. Any ideas why this is happening. Don't want to intialize unless I have to. Last resort is to call ESI on Monday morning. Thanks in advance for any help you can give me.
