    I have the same problem with my MD400 series. Disconnecting the batteries did not help, responding to the solution of the other individual. What else to try? Any suggestions?

We removed the batteries from the base as well as the handset, put them back in and then it worked!

    Tried a lot of things-didn't resolve the issue. I removed the battery--BINGO! (In the excited words of Dr. Frankenstein, "It's ALIVE! It's ALIVE!!" Thank you. lol
