What is the most probable cause of a general electric dect 6.0 cordless phone displaying random info.

SOURCE: GE 21008GE2-A Dual-Handset cordless phone

Here's what seemed to work for me.

Hit the button that says ringer. then hit the number 1
then hit the button marked program (it is also the
mute button). Some combination of those moves
helped me go from Ringer OFF to Ringer ON.

Hi :I have the same problem and the dealer couldn't help me .I replaced the battery but that wasn't the solution.Glad to see i'm not the only one with this problem

SOURCE: Handset voice very low and LCD display is blank

My 1740 handset volume was also low. As a shot in the dark I changed the speaker and it fixed the problem. I got a new speaker from www.panasonic.com .

I had the same problem. What worked for me, after several unsuccessful registration attempts, was to disconnect the phone handset battery for about 1 min and then reconnect the battery. Run the handset registration procedure again. It registered for me on the first attempt after the battery reinstall. Good luck.

SOURCE: Static electricity

I had the same problem when I answered my cordless phone static charge went thru me and into my phone and I had now display, so i changed the batteries in the handset and it worked. So I hope this works for you.
