How to register phones to base unit - uniden dct648

I have 4 dcx640 handsets to register to base unit (dct 648).  When I use the drop-down menu feature, the unit says the system is 'unavailable'.  I have unplugged the base unit, held down the delete key, re-plugged the base unit, got a beep and a zero in te display, hit the delete key twice and now all the phones are unrecognized.  What to do?

Unplug the unit again and press the intercom/find handset button while you re-connect the adaptor.  Then dock the phone unit once again and it will re-register.

How do I register my Uniden handset? It keeps saying it tis searching and then out of range even though I have it on the cradle


Which Uniden phone do you have? Some should register with the handset in the base unit cradle for 30 seconds to a minute. Others need to be within a few feet of the base but not in the base charging.

For the models that need to be registered with a multiple step process, first make sure that the handset is fully charged; this could take 15 hours. (Make sure the battery is properly connected; if it is loose, the registration may fail. If the battery may have been sitting in a warehouse for months, you may want fresh batteries even for a new phone.) Make sure that the base is plugged in (power and telephone line). I like to check the phone line with a basic corded phone for dial tone if there are any issues with a cordless phone. With some Uniden phones, a registration problem can be cleared up by disconnecting the battery and then reconnecting it before attempting to register the handset. (Make sure that you do not have more registered handsets than the base can deal with. You may need to deregister all of the handsets and start over. Make sure that the handset is compatible with the base.)

The rest of the process requires you to have the handset close to the base and be relatively quick. (You need to tell the handset to get the registration information from the base and the base to send the information before they time out). For the D1688, at the base, you need to press Menu and go to the Register Accy submenu. Press Select. Then press and hold # on the handset you need to register until you see Registering Handset. Wait for the Registration Complete (or Failed) message.

For the DECT1060, the procedure starts at the handset. Press Menu and navigate to Add. Settings. Press Menu/OK and navigate to Register and press Menu/OK. Select the base number and press Menu/OK. Then press and hold the Find HS button on the base for 3+ seconds until the unit enters registering mode. Now on the handset, you need to enter a PIN that matches the one set for the base. (The default is 0000.)

If you still have problems with registering the handset, then it's likely that the transmitter or the receiver for either the base or the handset may have a problem sending and receiving the codes that synch the base and the handset. Most Uniden phones are not meant to be user serviced for this type of proble. You will need to contact Uniden if the phone is under warranty or decide if you want to replace or repair the phone through Uniden's support.

The manuals for all Uniden DECT 6.0 phones are available as PDFs from Uniden. See http://www.uniden.com/bin/venda?ex=co_disp-view&bsref=uniden&scat=dectphones_mnl for a list of all models or search for your specific model. On the manuals pages, the models are listed in numerical and alphabetical order.

I hope this helps.

How do i add another handset "uniden 6.0" phone to an existing phone and base unit of the same brand.I need the step-by-step instructions please. thank you!


First make to get a compatible handset.

For the Uniden D1660-2, the compatible handsets are DCX160 and DWX337. Make sure that you have not exceeded the number of handsets that the phone can support. The D1660-2 can support 12 handsets unless you use any DWX337 handsets. Then the limit is 6. (If you have more handsets, you will need to deregister some of them first.) Then allow the handset to charge. If the handset is reading "not registered", then place it into the base unit. You should see "Handset Registering" for about 30 seconds; then it will read Registration Complete. The manual for the Uniden D1660-2 is available here: http://www.uniden.com/content/ebiz/uniden/resources/ownersmanuals/D1660-2om.pdf . This is the most common Registration for Uniden phones; there are a few exceptions (depending on the base or the replacement handset). Check the appropriate manual (see below to find the manuals).

For the DECT4096, press Menu on the base and then navigate to Handset Register. When you see Handset Registering on the base display, press and hold # on the handset to be registered until you see Handset Registering. (It takes about 2 seconds.) After the display changes to Handset Registered, check for dial tone.

On a few Uniden phones, there is a Page/Handst Register button on the base. On those you navigate through the Handset menu to Handset Register (Menu > Handset menu > Handset Registration). Then press and hold the Page button until you hear a beep. Then wait for the registration to be completed.

Most Uniden manuals are available here: http://www.uniden.com/scat/cordlessphones_mnl . Select your type of Uniden phone and scroll through the list to your model or use the search box to directly search for your phone and the manual.

I hope this helps.

I have Uniden DECT1480-3. I purchased two expandable handsets, but I cannot figure out how to get the new handsets to register with the base unit.


Up to 6 handsets can be registered with the DECT 1480 phones. I have the 5 phone unit and needed to add the 6th phone. All I got was "Searching" in the display and the battery wouldn't even charge!

So here's what you have to do to get additional phones (up to 6 units) to work with the base. If you can get past step 1, it's a snap...

Step 1: Place a charged battery in the handset. This could be a problem if all your handsets are not registered, since unregistered phones don't charge (who thought of that design?). What I did was SWAP the battery from an already registered and charged phone with the new unregistered phone.

Step 2: Here's where the magic happens. Press the 'END' and '#' keys simultaneously... hold them down until a System Reset menu appears. Select "Deregister HS" and press Menu.

Step 3: Now, do the same thing again (hold down END and #), but this time select Base Unavailable and press Menu. You will see Base Unavailable Yes/No... Select Yes. Then place the handset in the base, wait a few seconds, and Voila!. it's registered. You can even change handset numbers using this menu if you play around with it.

Thank you, helpful employee at Costco for supplying the magic code. And hey there, UNIDEN... including this in the operation manual would have saved many customers much grief with de-registered phones!

Enjoy!

Uniden TCX905 cCordess phone Handsets # 3 and 4


If the handsets are not currently registered to any base, the SYSTEM RESET menu won't appear.

If the TCX905 handsets in question are actually expansion handsets from another Uniden Phone System, they are not true TCX905 handsets. To verify, remove the battery cover and battery, then look at the inside label. If it lists the model of a TRU9xxx phone system, your handsets are NOT TCX905.

Uniden unfortunately has programmed the expansion handsets from SINGLE LINE TRU9xxx phone systems to NOT REGISTER against the TRU9466. (Those same handsets register fine against predecessor model TRU8866 though).

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.

Handset Fails to Register


It is quite possible that you'll need to go into the menu settings on your base-unit and reset the unit or restore factory default, whichever option it gives you. Also, look in the menu on the phone to see if there is an option to reset the handset also. After resetting the unit and/or handsets, try to register the handsets again, one at a time. If that still does not fix the problem, you may have handsets that are not compatible with your system, or your system may not be able to support that many phones. However, if you have the right handsets, and your system can host that many handsets, then I'm confident that resetting the unit and re-registering your handsets should fix your problem.
Hope this helps! Have a nice day!

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.
