Re: Uniden handset doesn't work

If you replaced it with a working new battery pack. You can test it in another phone. The Battery pins on the phone board could have a poor connection which requires soldering.

Batteries won't charge

There are a few reasons why a battery won't charge. Make sure that the contacts on the phone and the charging cradle are clean. (Unplug the base or charger.) A pencil eraser is good initial cleaner; electronic contact cleaner sprays are a second option. Remove the battery and check the contacts inside the handset and the battery as well. Next replace the battery pack. If you add a comment with your phone's model number, then I can try to find the correct battery. (Stores like Battery Mart may have a compatible battery.)

The final possible problem is that the charging system is bad. If your phone has multiple handsets, try a different charger. If the phone allows you to add handsets, try getting a new handset. The new handset will come with a new charger. (I've never seen the chargers sold without the handset but you could try Uniden customer service. If the base station is the only handset cradle, you'll probably need to replace the phone if a new battery and clean contacts don't work.

If your Uniden phone is under warranty, contact the company.

I hope this helps.

After de-registering handset, handset displays [REGISTRATION FAILED; UNAVAILABLE] when trying to register handset.
This worked for my UNIDEN TRU-9480-2
1) Remove handset from base
2) Remove power cord from back of base
3) Press and hold the [find hs] button on base as you plug the power supply back in; the charge light should then be blinking.
4) Return handset to base and it should register

Phone says searching

Bring the handset that says searching into the same room as the base and see if the handset stops searching. Next unplug the handset batteries (yes from all handsets) and the base power cord (from both the base and the wall outlet). Wait a few minutes and then reconnect the batteries and base power cord. Next try to de-register and then re-register the handsets. (If you add a comment with the phone model, I'll help you with this step. Uniden has the manuals for their phones on their site: .)

If this doesn't help, next try a new battery (and make sure that the battery is fully charged) for the phone. (If the phone is under warranty, contact Uniden. Note: batteries lose their ability to hold a charge over time. This includes the time on the shelf in the package.)

If a new battery doesn't help, then there is something wrong with the handset. Decide if it is worth having the unit fixed if the phone is out of warranty.

I hope this helps.

(I'm assuming that both handsets are cordless. If you have a corded/cordless model, then check that the base has power before you go farther with the above diagnostics. The power brick should be warm. We had a cordless phone on a power strip (UPS) that got turned off. The handset was searching for a signal that wasn't being sent. If you have power to the base, try sending the Find Handset message. The problem could be either the base or the handset not sending and receiving the signals between them.)

I have a GE model 25836CE-B cordless phone. My problem is this: when the phone is off the charger base, after a few minutes it will keep on beeping even if no one pressed the paging button at the charger...

Actually, you can't overcharge the battery. The base is designed to hold the handset indefinitely. Once the battery is charged it doesn't do any damage. You probably just don't have the battery charged enough to use the phone. Leave the handset on the base overnight, let the thing charge, and it should work properly.

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.

That sounds like the battery is not charging properly. When in the charger there is enough voltage passing to power the handset, but when pulled off the charger it must rely on just the battery. I suspect you replaced your battery because you were having a problem, right? Your problem may be dirty charging contacts. Try taking a pencil eraser to your charging contacts on your handset and base. Try charging your handset again, and ensure your charge light comes on when doing so. Let it charge overnight. Hope that helps. CG

Registering Handsets to the Base
Whichever handset you choose to charge in the base is automatically
registered to the base. Any additional handsets must also be registered to
the base before you can use them.
Be sure both handsets are fully charged.
One at a time, place each handset in the base. The charge/in use LED on
the base begins to flash, indicating the base is registering the handset.
Wait for at least five seconds, then pick up the handset and press
[talk/flash]. If the display shows TALK, the handset is registered. If not,
place the handset in the base to try again.
Press [end] and continue with the next handset.
Once both handsets are registered, it doesn’t matter which
handset is placed in the base or the charger.
When you charge the handsets, Caller
ID summary screen and the name of
the handset appears.

This can be find from uniden website.

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 :)
