Phone display shows second line in use when it is not

I have Uniden 5.8 GHz phone system. I accidentally unplugged the power converter from the base unit for the main phone (there are three satellite handsets as well). Ever since the display on all the phones indicates that the second line is in use regardless of whether it is or not.

SOURCE: Main handset won't work; additional handsets do.

Check that you have the larger power adaptor connected to the base unit.

I had the same problem. Once I read the owners manual I found the charge light blinks to indicate that you have voicemail waiting to be retrieved via telecom provider. Much to my surprise I have a voicemail account I never requested.

Another mystery solved - I now know why I missed so many messages.

SOURCE: Uniden 5.8 GHz Digital cordless w 3 handsets interference background noise no matter where we are in the house or which handset we use

This is possibly caused by the internet connection.
Try new ADSL filter.
You need one each per device.

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.

My uniden phone says - out of range

Uniden wxi477 out of range fix

This problem arises when the handset does not communicate with the base.
These are the steps:
1: Deregistering the handset
2: Registering the handset to base

Deregestering clears the stored (incorrect) base information on the handset.
Reregestering allows the base to assign a new ID for the handset.

Deregistering- press and hold the OFF (red button) and the # button on the handset for 5 seconds. select base unavailable and press OK. Are you sure appears. select yes and press OK. you will hear a confirmation tone. The handset will delete its own base information without trying to contact the base. It will now display MODELS VARY PLACE HANDSET ON THE BASE FOR REGISTRATION.

Registering the handset with the base- Make sure the tel. line and power is plugged into the base.
Press an hold the register button under the base (located between the tel. line and yellow power socket under the base) for 5 seconds until the red light flashes. At the same time press and hold the # button on the handset for 5 secs. You will hear a tone and It will now display REGISTRATION COMPLETE.

If it says registration failed: Retry the registration steps. Make sure the handset have enough battery power. If not charge for 15-20 hrs.
Check your connections on the base and make it is getting power.

The Steps above was my fix for the uniden wxi477 out of range problem.

Good luck.

No dail tone --but phone line is connected


If the dial tone is not heard check the volume. It may have accidentally been muted or turned down.

Is the phone line plugged into a surge protector? The surge protector may have stopped working or blown a surge, a sudden burst of electricity, which may have caused the dial tone in your cordless phone to go. Unplug the phone line from the surge protector then plug it back in and see if you get a dial tone? It could be that the phone line plugged into the surge was loose.

Try a different phone plug, outlet.

If the other phones on that line work OK, disconnect all the phones connected to the line, leave them all disconnected for 3 minutes, and then connect one at a time.

If still a problem and the other phones on that line work OK, give this a try:

Unplug the battery in the handset, unplug the phone line from the base and unplug the electricity from the base. Leave everything unplugged for an hour or two. That way you can get more of an idea of whether your phone will work. After an hour or two, plug in everything.

Hope this helps.

Phone disconnects and shows "out of range of base" during calls

Press "Menu", Select "Handset Setup", select "Select Base", and then on that Select Base screen, move the arrow next to "Auto" and press select. I have been told this should solve your problem.

Uniden 2.4 GHz cordless phone won't register to base

Same happened to me. Unplug the base from power and the phone line for 30 minutes. Same for the handsets - all. Take out the batteries. Retry. After it says 'registration failed'. Leave it in the cradle. Several minutes later it found itself.

Phone won't hang up

I solved this exactly problem by doing this:
1) unplug base station from phone line
2) unplug base station from power cube
3) open each phone and disconnect battery (do not replace phone in charger; just let it sit)
4) wait 30 minutes (per instructions from Uniden)
5) reconnect batteries in phone sets
6) reconnect power cube to base station
7) reconnect base station to phone line
8) test: make a call. Hang up. Wait one minute. Pick up line and see if you get a dial tone.
(Basically you're "rebooting" the system. You don't know where the fault lies, so you power down every component to make sure you get it. The '30 minutes' is longer than I'm used to, but after being on hold with Uniden tech support for 20 minutes and finally getting through, the instructions from them were very clear: AT LEAST 30 minutes. OK! I did it - and it worked!)
