On most models you can find an option in the menu for De-register? In that case you would select that option and select to deregister the handset.
TRU88 models you go to the main menu and go to De-register HS select yes to deregister the Handset.

DCT5 and DCT6 models: Press menu on the handset. Go to System Reset and Press select. Go to Deregister HS and press select. Arrow up to yes and press select. Then go back into the menu. Go to system reset and press select. Arrow down to Replacing the base and press select. Arrow up to yes and press select.

DCT7 models: Press and hold "end" and "#" until the system reset menu appears on the display. Then follow the instructions from above for the DCT5 and DCT6 deregister procedures once your into the menu.

TRU4 and TRU5 models: Press and hold xfer/del and end until "de-register?" appears. Use the plus+ button to go up to yes and press select.

To register any of the following phones please see you owners manual under either:

•Register handset or

•Register the digital security code.

How do you register a old uniden SSE27 handset to a new Uniden SSE37 base

The following is taken directly from the SSE37 owners' manual:

Registering a handset
If you see a "not registered" message on a handset,
you must register it to a base before using it.
On the base, open the menu and select
Register Accy.
On the handset, press and hold #/DND
until the handset display says
Handset Registering (about 2 seconds).
Wait until the handset display says
Registration Complete (about 30 seconds),
then pick up the handset.
If you don't hear a dial tone or the display says
Registration Failed, charge the battery completely,
then try again.

Good luck!

Are you sure of the model number? The D1680 should register the handset when you put it on the base for 30 seconds. (You should see Handset Registering followed by Registration Complete.) Then press Talk/Flash to check for dial tone. On this model if the registration fails, charge the battery (or replace the battery and then charge that). Then repeat the registration.
The manual for the Uniden D1680 is available here: .

For other Uniden phones, like the DEC1060, you need to navigate through the handset menus to find the Handset Registration command. Then press and hold the Register Handset (Find Handset) key on the base for 3+ secondsThen the base and handset will synch. (Low batteries could interfere with the process.)

For the D3288, you access the base menu for Register Accy and then press and hold # on the handset for 30+ seconds. (You will see Registering followed by Registration Complete.)

Additional Uniden cordless phone manuals are available here: .

I hope this helps.

(with a flea market phone, my first suggestion is to try a new battery for the handset. They only have a given number of recharge cycles and you do not know the history. However, sometimes the chargers do fail and a new battery will not work. In that case, the phone should be replaced. It isn't worth the cost of out-of-warranty repairs.)

I have a uniden TRU9488 preregistered handset from factory, which for years no problem, but stupid me thought "what is this register" and hid register, and now my handset won't work. followed...

What happened is you have deregistered your handset from the tru9488 base. To correct this, you must register that handset with the base. See for short and sweet instructions for doing this, reproduced below:.

My cordless phone says "to register see owners manual for help" How do I get the phone working, it is a uniden DECT 6.0 Model DECT 1588-2

With the phone in standby, press MENU/SELECT on the base.
Move the cursor to select the Register Handset menu, and then press MENU/SELECT. Handset Registering will appear.
On the handset, press and hold # until the handset beeps and displays Handset Registering.
When the handset has registered to the base, the LCD will display Registration Complete then show the handset ID number.
If the display shows Registration failed, repeat the process again.
Note: If a handset has ever been registered to a base, reset the handset before you register it to a new base

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).

1 Answer

We had Uniden model TRU8866. Handset #2 was damaged and lost. We purchased a new phone through Uniden. It says Set #4 on it. We would like it to say #2 The new phone is a Power max5.8ghz.

In order to re-register handsets with TRU8866 base unit, you have to reset the base unit, de-register the handsets, and then re-register the handsets. To reset the base station, disconnect the power from the base and then press and hold the CID, Intercom, and Exit keys while you connect the power. Wait for the beep, and let go of the keys. Now re-register the handsets - the first one will become #1, and so on.

To register the DSS7905 handset:

Place the handset in the telephone base charging cradle to begin registration.

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 :)
