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!

Two sets Uniden phones with base, second handset: incompatible?

I had the same problem with a Uniden 3355 handset and 2355 base. With the new handset I pressed "Menu" and selected "System Reset". I then Selected "Deregister HS" and followed the prompts.
Once this was complete, I returned to "System Reset" and selected "Replacing Base". Following the prompts, when it said "Register Handset" I put it in the base of the 2355, and within a minute it had registered, so both handsets used the base of the 2355!

Tru 9496


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.

Deregister lost or broken phones

Some tricks from a helpful Uniden rep:

holding down end+# keys at the same time on the phone for about 10 secs (you will hear a beep) will deregister the handset. If you have a dead handset and want to deregister it from the base, you have to reset the base. unplug the phoneline and power. hold down the "delete message" key, plug power back in. about 10 secs later, you will hear a long beep (theres a short beep upon powerup as well). At this point all handsets are deregistred and you will have to reregister them with the end+# trick. this way when #1 handset is dead, you can make a working one #1 and get the broken one fixed emotion-1.gif

BTW, this is a woot warranty, not uniden warranty. however the uniden rep gave me the number to the people who refurb (rox0rz!) these. I'll post an update when I finally get ahold of them (and the number if its actually helpful)

If you bought the base and handset together they should already be registered. If not then the instruction manual is downloadable here: MANUAL

The relevant section is on page 16 - here is a copy:

4 handsets can be registered to the base station. A handset
can only be associated with 1 base station.
�� To register another handset
First enter registration mode by unplugging and
plugging back in the power adapter to the
electricity supply.
Handsets registering / unregistering ( )
�� To unregister the handset you use
enter the RC code*
�� To unregister all the handsets (except the handset you are using)
enter the RC code*
Once the menu is selected, enter the RC* code written under the base and press
to confirm.
Warning : If you wish to associate a non-Philips handset to the DECT 211 or DECT 215 base
stations, make sure that these handsets are GAP compliant otherwise they will not operate properly.
*RC code
Code) is
written under
the base.
Warning : Once unregistered, the handset is no longer operational.

Please rate my assistance this should be a fixya!

Uniden handset TCX905 with base unit TRU8866-if compatible?

I just successfully registered 4 TCX905s with my TRU8865 base - it's documented in the TCX905 manual.

Be sure the handset you want to register is fully charged.

Remove the handset you want to register from its charger.

Now unplug the AC for the main base, hold down the 'find handset' key on the base and plug the AC in again, when it beeps, you can let go of that button.

Hold down the '#' on the handset you want to register, it will show 'Registering Handset...' and when it beeps, it's done - registered, you're good to go :)
