Question about Uniden DCT748-4 Phone

Open Question

My phone will not hang up the line unless I unplug the base from the jack. It worked as usual all day, then it just never hung up. Already checked the line with the phone company and it is 100% the phone/base itself, not the cord either already changed it! I am also using the same cord on a corded phone in the same jack and it works everytime. I have even tried other jacks. None of the handsets will work. Now I have to walk to the wall everytime I use the phone just to hang it up...and even then unplugging it doesn't always work unless I do it again. Once in a while it has worked, but only 5 times out of about 150 or so. Is there a reset somewhere or something that will fix this little issue of mine???

OK sorry guess I was thinking you had 2 handsets.
My suggestion is go to the Uniden website and maybe see what they have there.

Maybe do a search on the Uniden site for that Automatic Digital Security Code thing, seems it would be easy to fix, just a matter of how....

In the meantime I'll do some searching and see if I can help and find a fix

SOURCE: 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!)

My AT &T cordless phone says no line. We changed the battery, but still no service

99% sure the problem is not the phone or the base unit. Find an old school phone or borrow one and plug it into the jack at the wall. Even if it works there but cord to the base unit could be bad. It's a dead at the Jack on the wall check another Jack in the house if not there then call your phone company.

EL52500 Phone base & 4 handsets have static, message Line in Use. Bought new phone, charged, connected - it says no line. Have dial tone at phone line into house.

Sounds like your phone has a short. If you see the message "line in use" call your number, is it busy, now unplug your phone and call your number again, is it ringing? Indicates a short, possibly in your equipment. As for message " no line" is the electric connected to the phone and did you check for dial tone in tat particular jack with a known, working phone first...just to make sure there's dt @ the jack. Good Luck :)

Phone won't hang up, stays on the line even after hitting 'OFF' button

We recommend you test the main base unit with a different telephone cord on a different telephone jack.

L7780 cannot get dial tone on 2-line outlet. Are there any work arounds to this problem?

There is a problem either with the Line Interface Unit (LIU, also known as the fax/phone line connector) or the fax hardware, because the unit is having problems sending or receiving faxes. The unit may hang on "Initializing." This document explains how to troubleshoot the LIU and fax hardware. SOLUTION: Please perform the following: Front panel hangs on "Initializing"
  1. Pull the power cord connector from the back of the base unit to recover from the error.
  2. Unplug the LIU from the back of the ADF. It is located on the left side (facing it), and is where you plug in the telephone lines.
  3. Plug the power cord back in, power it up, and see if it hangs without the LIU inserted.
  4. If it does not hang without the LIU inserted, power the unit down, plug the LIU back in, and power it back up. If it hangs, the LIU is faulty.
  5. If it does hang without the LIU attached, unplug the ADF from the base and see if it hangs. If it does, the base is faulty.
Testing the LIU The primary test for the LIU is whether or not you get a dial tone. Sometimes, you need to re-seat the phone line several times to get a good connection. If after trying the things below, there is still no dial tone, or initialization hangs, the LIU may need to be replaced.
  1. Verify that the phone line is connected directly from the wall jack to the plug in the LIU that says "To Wall Jack."
  2. Verify that the LIU is plugged securely into the product. If it is not, there will be a message at power-up saying the LIU is not connected. If it is, the date and time will display.
  3. If the LIU was re-seated, cycle the power on the unit. The unit should display the date and time.
  4. Unplug all other accessories, like a telephone answering machine or modem. If the LIU appears to work fine after unplugging them, these accessories may be interfering.
  5. Place a document in the Automatic Document Feeder (ADF). The display will flash "Document Loaded."
  6. Press Start Fax to verify there is a dial tone. If so, try sending a fax.
  7. If there is not a dial tone, unplug the product from the wall jack, and plug in a regular telephone to verify there is a dial tone at the wall jack.
  8. If there is no dial tone on the telephone, the wall jack or phone line may be faulty

Picking up and Haning up problems. "Rls" key "Line 1-4" keys

Can you sheck something for me; under your phone where the cables are plugged into, there are 3 types of jacks... 1 jack is to plug the phone into the wall 1 jack is to plug the handset into(picture of phone handset) 1 jack is to plug a headset into(picture of headset)
Check and make sure that the handset is plugged into the handset, and NOT the headset jack... and move the cables if that is the issue. Your problem sounds very familar to your handset being plugged into the wrong jack on the bottom of your phone, and it is more common than you think.

I have a Lucent model 103H. I no longer get a dial tone when I push the line buttons. I only get static. I replaced the two AAA batteries yet I can still not dial out or receive incoming calls. Do you have...

hmmm .. the lucent 103h is called a "partner 5 slot (carrier) chassis for partner internal phone systems .... used in business usually for multiple phones... unless you have a home phone by that same name .. if you do have a "partner" system then lucent repairs those for about $65 ... check the line before considering repair ... if you have a single standard phone that just happens to have the same name .. then you may have a damaged telephone line .. you can test that by unplugging this phone and temproarily plugging in another .. if it works then there is likely damage to your original phone .. usually its lightning surge protectors that fail (due to a nearby llightning hit) ...if a second phone doesnt work then there is usually a service jack near where the phone line comes into the house .. you can plug in there .. if the phone is bad there also then its an outside maintainence repair job .. thats free from the telephone company .. if the test phone works at that test jack then its often your responsibility to arrange inside line repair .. unless you have an inside line repair contract the telephone company may charge for inside repairs .... your phone company can talk you thru using the service jack .. you would first disconnect the rest of the house by removing a connector from the service jack then you would plug in a standard phone to that jack .. that makes sure the problem is either inside or outside .. if your phone happens to be chordless then there is more things to consider .. the handset and base have to develop a relationship in order to work properly ... that relationship can be lost in a power failure and must be reestablished .. usually thats done by removing power from the base for a minute then connecting it again .. so there are a lot of possibilities depending on what type phone you have ...

Move closer to base

Either the phone is not registered to the base unit or the RF module is broken. It could be a bad battery but unlikely unless very old or you have not charged it. You should check the manual for registering the phone to the base unit.
