Question about Uniden TRU4485-2 Cordless Phone

8 Answers

Phones stopped working

Our two handset Uniden 2.4 ghz and our Walmart special have all quit. When you pick up one of the Unidens, there is dead air, almost like someone is on the line, but no dial tone. Nothing seems to help. I checked the line outside, we are in a RV, and it is connected, but the line was picked up by the maintenance guy to cut the grass. Thanks so much for any ideas as to what is wrong.

    We have 4 VTech phones and after a short incient where the incoming phone line was accidentally disconnected, all the phones went dead and we couldn't call out or get calls and there was no dial tone. How do we get the phones O.K. and working again? The incoming phone line was reconnected after about 10 hours of being disconnected from the wall.

    i was in the middle of a conversationa nd suddenly the line went dead, yet it sounded as though someone else in my home picked up a phone, although we only have 1 phone, the one i was on. when i would speak there was a loud echo, like an intercom. i have tried everything to fix this. we have no dial tone, and can not call out, and all incoming calls (ringtone can not be heard) go straight to our voicemail. i know the battery is charged, and everything seems connected. please help!

    I have the DXI 5686-2, a 5.8 GHz extended range cordless phone I bought from Target 6 months ago. Both phones were "fuzzy" even when I first used them. We ended up only using the main phone and it was only acceptable within a few feet of the base.



    It has all of the sudden stopped working. There is "dead air" as described in another posting when I push the talk button. The red light is still on and the other phones in the house work - both cordless and land-line. Target won't replace it because it has been longer than 3 months and I don't have a receipt. Any suggestions on a fix? Will Uniden replace it?

I don't have a solution, but I can say that my phone does exactly the same thing and I know for a fact it isn't the line because I'm using another phone on that line right now.

I have the same problem if my cable ever goes out since I get my phone service through the cable company. Try another phone and see if that works and if not it's time to call your phone company.

I had the same problem. I finally just unplugged everything from the phone and the batteries and let them unplugged for about 5 min. When I put everything back together it worked. Hope it works for you.

Check the batteries if they are working with the help of a mulimeter

Posted on Dec 06, 2007

Make sure that the jack are in properly and then make certain that the battery is properly installed in the phone. I did this and problem cleared up

Posted on Jun 29, 2007

Can't suggest a solution; but, can let you know that another phone plugged into the same line works fine. Obviously, it's NOT a line problem. Thx anyway.

Posted on May 30, 2007

My troubleshooting instructions tells me to "unplug the base unitsAC adaptor to reset the unit and then reconnect the adaptor and try again." I did and it worked, However I have had to do this several times during the past week.

Sounds like a line problem. Take the phone to a friend to test on a known good line and post back. If the phone works on another line, better call the phone company. Good luck

SOURCE: No dial tone on handset

It may not be registed with the main unit. You may need to register the handset. With my uniden all i have to do is put it in the main base until it says what handset it is (it should be a number).

If you have any questions please dont hesitate to ask

SOURCE: adding a new handset

You need to register the new handset with the base.
In Global settings De-register the new handset then place it on the main base unit connected. It should then register.

SOURCE: No dial tone and no ring on Uniden 5.8 GHz

I have the same handset and the 2nd one seemed to stop working after working great for 2 yrs. I placed both sets together and hit the PAGE button on the main handsets cradle. Both phone's were paged and, for some reason, the 2nd handset reset. It worked for me...or at least, something in what I did worked. BTW, H1 and H2 shows in upper right side (or at least it did after I paged)...and I made sure to put the phones in the correct cradle (H1 is the main handset). I just did this so hoping it continues to work!

You may have a problem with your battery. Usually the rechargeable battery goes bad on those units. Swap the battery from the working handset to one of the non working ones.

Phone sees call, but can't pick-up. Can't get d-tone to call out?


Just a suggestion (without knowing what troubleshooting steps from your manual you may have taken): Remove the batteries from the back of the handset and then put them back in after a few moments. My Panasonic KX-TGA8231B (DECT6.0) phones were acting up just like your Uniden is. All functions returned after this power interrupt "reset" with the batteries was done. Hope that helps. Good luck. - - -Gerry

You can get a full manual with all the instructions for your UNIDEN phone HERE

I suggest downloading a copy and printing it out to keep with your phone.
You'll need it for all the pairing with the remote handsets too.

Can't talk on both phone at same time. second on is always dead.


The DXI4286-2 is an Analog phone, it does not allow for both handset to be used at the same time. You can transfer a call from one handset to another, but cannot talk on both at the same time.
The following is from the user's manual for your phone:

Unavailable message is displayed
on the LCD screen of the
handset.
• Make sure the other handset is not already in use. Both handsets cannot be in talk mode at the
same time.
• Place the handset in the main base for at least 5 seconds to re-register to the main base.
• Make sure the handset is not too far from the main base when trying to use.

You might want to try one of the DECT or a Digital 2.4 or 5.8 GHz phones, they allow you to use multiple handsets at the same time.
