PANASONIC KX-TG2258 E3 ERROR CODE (by 7 users)

This method worked for me!! you guys should try this.

i've copy this review from amazon.

by Kane Doerfler

"After a brief power outage from a thunder storm, I also experienced an e3/lights blinking error. I unplugged the phone and plugged it back in several times to no avail. After doing this a couple of times unsuccessfully, I hit the "STOP" button on the base immediately after plugging it in (before it completed booting up to show the "e3 message")and it reset itself and now works fine (or as well as it did prior to the e3). Try it before tossing yours in the garbage"

thanks to Kane. I saved my phone~!!
