Question about Uniden Cordless Phone

1 Answer

E4 trouble condition comes up on screen after power up

I have a Uniden TRU9485-3 cordless phone. After a power outage yesterday I turned the phone back on and the display on the main unit reads "E4".

I had the phone plugged into a surge arrestor.

Any idea what this code means?

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.

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.

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


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.
