    My Uniden 5.8 digital phone base also has the e4 error code. The phones are seven months old. I have tried calling the telephone number in the owner's manual and have had no luck in reaching anyone.

    I, too, have the e4 error and cannot get help resolving this. My phones are not working at all.

    The main base displays E4 24/7. The handsets say "Models vary! Place you handset on the base to register" and when I do that, it says, "Please wait...Registering." And then the handset changes back to "Models vary etc." I tried unplugging the base for a few minutes and plugging it back in. As soon as it was plugged back in, it displayed 88 a few times, and then back to E4 right away.

    I have the same problem with the E4 error code for my Uniden9480 Cordless phone.

  • Anonymous Mar 26, 2008

    Same E4 showed up on my TRU9085 (same as 9485) last night after a power outage. It doesn't respond to any buttons.

    Apparently some of the base units can be reset and come back to normal, due to a corruption in the answering system data. It wasn't the case with mine...

    Anyway, I've called Uniden and the very nice lady gave me the hard reset procedure (not found in the User Manual):

    - disconnect the power from the unit

    - press and hold the following 3 buttons while connecting the power: DND, *(star) and the left hand-side top silver button.

    You should hear a long beep if successful. You'll need to re-program the base, since EVERYTHING WILL BE ERASED INCLUDING: messages, caller ID, etc.

    This procedure will bring the system back to Factory Default status, so again: ALL THE STORED DATA WILL BE ERASED.



    I hope this helps some of us having this E4 problem.

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.

    I just spoke with Uniden customer support. They said that the E4 message is an error code saying that phone is "broken beyond repair." They said for me to return the phone to the store that I bought it from and if they wouldnt take it to call them back and they would see what they could do about replacing it free.

    Here is more info directly from a Uniden email:



    Our Solution :
    Thank you for using our system.



    Thank you for contacting Uniden with your question.




    If there is an error code with an E followed by a number it would be an internal issue in the base unit. Uniden does offer a limited 1 year warranty off the proof of purchase. The proof of purchase is required for warranty service. Uniden phones that are purchased in the US or Canada are only made for use in the US or Canada. Using this phone in other countries will void the warranty and also may damage the unit due to the differences in electrical standards. Also the unit may not work as specified.




    Uniden's warranty only covers purchases made for new products purchased directly from a verified retailer. Units purchased from E-bay, garage sale, etc. or companies that refurbishes phones and then sells them would not be covered under warranty. You would need to address this with the place of purchase or you may take advantage of the Out of Warranty procedure.

Same problem showed up on my 9085 (same as 9485) last night after a power outage.
Apparently this happens due to some corruption in the answering system and some base units can be reset back to Factory Defaults by a hard reset.
I've called Uniden and they gave me the procedure:
- disconnect power from base
- press and hold these 3 buttons while re-connecting the power to base: dnd, * star, the left hand side button of the 3 top silver ones under the LCD.

If the procedure is successful you should hear a long beep.

WARNING: THIS PROCEDURE WILL ERASE ALL THE STORED DATA ( MESSAGES, CALL ID, ADDRESS BOOK ETC)

Hope this helps some of us having this annoying E4 problem.

Good luck,

John T

Phone flashing 88 8 now flashing e4 cannot get dial tone.


Your manual may have the E4 code, but Uniden certainly will, if you contact their support site. This symptom often indicates a power or function issue with the base unit, and so make sure the base has charging voltage, and the terminals are clean (use a qtip and alcohol). When you contact Uniden Support, have your model number ready, since different units can have the same or different error codes programmed into them.
Good luck, and hope this helps.

E4 Error is showing on Uniden 5.8 GHz expandable phone. Power may have been disconnected. An ideas on a solution?


The handset displaying the message may have lost its memory of the base station. Take it over to the base station and reset it as when you first associated the handset with the base.

I hope this helps.

E4 trouble condition comes up on screen after power up


Error #4, You probably need to reset the phone by unplugging the main unit from the power source then plugging it back in abd re registering the handsets by setting them in the main cradle for about 10 seconds each. if this doesn't work try the manual if you have it still and see what E4 error means. Good Luck. Sometimes with electronics all you need to do when they wont work is unplug then and plug them back in while holding the power button on. This is amazing trick that no one wants anyone to know about. it works great on VCR's and DVD players.

No dial tone. No calls. Can't call out.


E4 IS AN ERROR MESSAGE, THE BASE IS NO LONGER GOING TO WORK, POSSIBLY A POWER OUTAGE COULD OF DAMAGED THE BASE.

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.
