Error Code The base unit is showing an error code E1. I can't find anywhere in the handbook what this stands for or what to do and of course it is a weekend and Tech Support is closed. I have unplugged it and waited an hour before plugging it back in. It still reads the same code.

Hi I have a Cordless Uniden Dect 6.0 and also another one that sitts on a bitter base. My problem is this: the cordless with the smaller base shows the message 'Searching' and wont do anything,...

Welcome to FixYa.

Reset the units/set up by doing the following:
  • Turn OFF all the HANDSETS.
  • Remove the batteries of the HANDSETS.
  • Unplug the power source of the BASE.
  • Unplug the phone line of the BASE.
  • Let it stay that way for 30 mins.
  • Insert the battery again of the HANDSETS, make sure it is charged properly.
  • Plug back the power source of the BASE.
  • Plug back the phone line to the BASE.
  • Register any handset that is unregistered (refer to manual).

Keep me posted.

Master phone is okay; slave phones show screen as "UNAVAILABLE" and beeps with error code sound...I can't find a resolution in the owners manual

That sounds like you have to synchronize it with the base unit.Put the slave phones in the base unit and try them.It may take 2 seconds,it may take a minute.It should work though.If you have already tried it and it still does not work,just comment here and I will get an autolink to what you posted.Good luck,Greg

Panasonic KX-TG2258 with E1 ERROR CODE

I was having that problem after cleaning the base and handset. It seems to resolve itself simply by disconnecting the power supply and possibly the phone input line for several hours. I reconnected my phone and it works again.

Customer support 1 800 297-1023 told me that this means the base unit is defective and can't be repaired. I also was told that none of my remote units are compatable with other models.

E4 error code

Exact same problem. E4, sent uniden an email thru their website though I doubt Ill hear any response. Very disappointed as the 9485 was working great until all of a sudden E4 showed up.

E4 error code

I called Uniden about the same problem.  They say it is a code that means it is defective base unit.  I had purchased it within one year and they will gladly send me a new one.  I don't know if they will offer anything beyond the one year mark. 

They say it was a spike in the power lines that causes this error.
