I have the base unit, 3 charging units and 4 handsets. All 4 handsets currently have "Place handset on Main base to register" on the their LCDs. All handsets are fully charged after 20+ hours of charging. When I place the handsets on the base to register the phone I receive a "Registration failed" readout on the phones. I have tried registering the phones in excess of 20 times for each individual phone. The handsets and base all have matching number formats (I'm guessing these are model, manufacturing and serial numbers). There are no buttons that will work individually on the phones (although the keypad will light up). I have also tried pressing the "end" and "#" keys simulaneously with no result. The base will answer phone calls on the intercom. Any assistance to activate the phones would be greatly appreciated. Thank you.
From any of the other phones simply press the MENU button go down to SYSTEM RESET and hit SELECT. Then choose Deregister HS and choose the one that is giving you the problem. Once deregistered, place the phone on the base and it will now register.
I had a very similar situation and I did solve it. You have to have at least one phone that is correctly registered. You press "menu", go to "system reset" (press "select" key), go to "Replacing base" (press "select" key), go to yes (press "select" key). Now all of your phones need to be reregistered, but that worked fine for each. Apparently it has to release all of the old registration data before it accepts new phones. As the other user (and I followed his advice first) said, good luck in solving your electronic problems.
I have contacted Uniden about solving this problem. They suggested I clear the eeprom on the handsets and reset the base. To clear the eeprom detach all of the batteries and reattach while holding the star and pound. You'll hear a beep. Press select and the unit will clear the eeprom. Now hit end and the unit will say "Welcome...something or other". Next unplug the base unit reattach while holding delete. Next hit delete twice...the base is reset. Apparently this is the last possible solution to marrying the handsets and base. This didn't work for me and the units have been declared dead. Good luck in solving your electronic problems.

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!
Welcome to Fixya
Place your Extension Phone Near to Main for Few times Until it Beeps.OR it Ask for Registration like Please Register or Something like that.Follow the Steps carefully to Register it...Then Check it for Dial tone to Confirm.Some phones may display that the handset needs to be registered. If this appears-Move the handset near to base/main unit & press the "Prog/Mute". Next, press the "Pager" button on the base unit .Then press the "Prog/Mute" button on the handset again to complete the registration.
Hope you got it....Thanks for Connecting FixYa
1. First, remove the battery cover on your unregistered TCX905 and look
under the battery to confirm that you indeed purchased a TCX905 because
some Uniden handsets were packaged as 905's but were not.
2. Take the fully charged unregistered 905 to the base unit TRU9496.
3. On the TRU 9496 base unit press "Menu" then select "Registration" and press OK
4. You should get the message "press the # key on the remote handset".
5. Depress the "#" key on the unregistered 905 and it should register.

Only one handset can be registered at a time. The handset ID for the supplied handset(s) was assigned at the factory, which has #1 or #2 in the display (#2 for models that have two handsets in packaging). When you register additional handset to the base, the handset ID will be assigned. 1) Before registering the extra handset, the battery pack must be charged for 15-20 hours. 2) Place the extra handset in the main base unit to begin registration. 3) While the handset is registering, Handset Registering will appear in the LCD. When Registration Complete is displayed, the handset has been registered to the base. If Registration Failed appears, please try these steps again.
