    all other hand sets work fine. I have 2 other sets

    So I accidentally dropped my phone in some water two weeks ago. Got the phone out and let it dry off for a couple days just like it says to in the book. Now when I hook up the battery to it, it does not ask to be set on the base to register. All it says is "Welcome! Please Wait..."

Mine cannot transmit either, i'm gonna pull it up and see, but you just have to put it on the base for a few minutes to register.

Using Uniden digital answering machine with 2 phones. When I pick up either phone to make a call a message appears on the screen, "connecting". . Tried another phone ,line good.


Check if the base power adapter is warm to the touch. If it's cold, then the base has no power. Test if distance between the handsets and the base is an issue by moving closer to the base. Check for any radio interference. Check if the handsets are registered. You may need to de-register them first. Try unplugging the base (power and phone line cord) then remove the batteries from each handset. Wait at least 15 minutes before restoring the power/batteries. If the base has a charging cradle, place one handset in that cradle and wait a few minutes. See if that handset works. Otherwise, try to register one of the handsets and see if it works.

If the problem persists, then the base probably has a problem transmitting or receiving the signals from the handsets. Unless the system is under warranty (one year), you should replace the system. Otherwise, contact Uniden customer support.

I hope this helps. Please add a comment with the model of the Uniden phone if you want directions for registering/de-registering the handsets.

The display only shows bars. Is my phone on the way out? It will be 5 yrs old in June. It is a 2.4 digital expandable system, model # DCT 6485.


sorry but i think it is time for you to get a new phone. Most phones these days are 5.8 or 6.0, which is much better than your 2.4. A new phone would mean better reception, more clarity, etc. They're always on sale at radioshack

Hope this helps! please rate how i did

I want to change my phone frequency


It sounds like your phones have registered with each others. Normally these phones are supposed to be digitally encoded. Try de-registering the phones and then register them again with the base. Hopefully this will fix your problem.

If they're analogue phones you can try scroll through the menu settings to change channels.

Can I use handsets from another DCT 748 unit to expand my DCT 748


Short answer:
No. This model of phone can only support 4 handsets. If you need more than that, you will need to have a second base unit.

Detailed answer:
One of my handsets went bad, and I just bought complete DCT748-4 package from a seller on eBay for a very good price. This set was used, but in very good condition. I didn't need the whole set - just one handset - but like I said, it was a good price. Anyway, I began by telling my old base unit to de-register handset #2 (the failed unit). However, I then found that I could not register the "new" handset with my old base unit because it was already registered to the "new" base unit. So, I first had to apply power to the "new" base unit and de-register the handsets. Then, I placed one of the "new" handsets onto my old base unit, and it said "Handset Registering ..." and registered just fine. Just for the fun of it, I placed one of the other spare handsets into my old base unit. It said "Hanset Registering ..." but then it beeped and said "Registration Failed." This is because I already had 4 handsets registered to my base, and the base can not handle a fifth handset.

My Uniden cordless' handset and the base wont register Can it be bypassed or decoded


Here it is step-by-step: 1. Remove battery

2. Hold down the * and # buttons and reinsert battery. You should hear a long beep. If not retry. (This is a bit awkward but hold the handset upside down and it’s workable)

3. Screen will be blank. Immediately press the right soft menu button.

4. Screen will report that EEPROM is clearing and then state EEPROM Clear Ok

5. Remove battery (yes again)

6. Reinsert battery (this time there’s no need to hold down any buttons)

7. Handset will reboot with Welcome screen and then state that phone must be registered (this is the status a handset should be in from the factory)

8. Place handset on base and it will register as normal

Handheld won't communicate with the base


i have the same problem and it has happened infrequently several times. you probably have to deregister the handset and re-register it and rest the base and handheld to communicate since my model is different from yours there may be differences in how to go about it but for my model the suggestion is as follows:

go to www.uniden.com for customer support here is a direct link to some frequentlt asked questions http://www.mycusthelp.com/uniden/supportfaq.asp?sSessionID=&lstFilter_a=&lstFilter_b=&lstFilter_c=&txtCriteria=hanset+won%27t+connect+to+base&optcond=2&iStartCount=1

Try resetting the phone system by using the following steps:

1) Enter the "System Reset" menu, then "Deregister HS" submenu.
2) Press volume/up or down arrow keys to select the handset ID to be de-registered from the list, then press the OK soft key.
3) Press the OK soft key. You will hear a confirmation tone. When de-registration is complete, "Deregistration Complete" appears.

4) After de-registering the handset, move to "Replacing the Base Setting" below. When you go through the deregister procedure if you get "out of range", That is okay. Go ahead and go to the next step.

Replacing the Base Setting
1) Enter the "System Reset" menu, then "Replacing Base" submenu. "Do you want to replace Base?" appears.

2) Press the OK soft key. You will hear a conformation tone. The base information will be deleted. When replacing the base is complete, "Please Register" appears, register the handset to the new base.

If your handset is reading out of range. Check the the main base and make sure you unit has power. This can be done by placing the handset in the main base to see if the charge in use light comes on.
If your main base isn't getting power please make sure the ac adapter is plugged in and is warm to the touch. If not the ac adapter would be damaged.
To resolve out of range follow the below steps.
Press and hold the end key.
Press and hold the # key.

Release the keys and select replacing base and press select.
You will see Replace base?
Select Yes and press select.
Now place the handset on the base and it should register to the base and allow for calls to be made.
