Query: E3 error code

This phone SUCKS! We spent a good $100 on this phone and all it does now is just display an E3 error message and all the lights blink. I suspect it has to do something with the circuits but I am not quite sure. Either way if you want your phone to last for a long time and be reliable, STAY AWAY FROM THIS PHONE! Panasonic really screwed up this time and I would hope they do something about this because this seems to be quite a frequent problem.
