Purchased addt'l handset to work with my CEZAI2998. It has a corded handset in the base and an accessory handset with charger. Needed another accessory handset; purchased EZX290 but can't get it to register. I now think that my CEZAI2998 doesn't allow an addt'l accessory handset, only the one that came with the corded base? Please advise. Thanks.

That type of spare is not normally available on phone sets. I guess you could contact Panasonic.

You can deregister all of the handsets and then register each one again for the LS6475-3. Make sure that all of the handsets are out of the base and all chargers and that the phone and all handsets are in standby. Then press and hold Find Handset on the base. When the In Use light begins to blink, release the Find Handset button. During the seven seconds that the In Use light is blinking, press and release the Find Handset button. Wait for the deregistration process to complete (about 10 seconds).

If the process fails, you may need to reset the base. You can do this by unplugging the AC power cord to the base or by picking up a registered handset and pressing Talk/Flash. Then you can try again. These directions are on page 5 (page 8 of the PDF) of the manual for the LS6405 handset. The direct link to this manual is https://cdn-media.vtechphones.com/media/p/document2/products/%7BD6DAD9B0-4C1A-4882-93D9-04124A59B629%7D/LS6405_CIB_V5_20160805.pdf . Then check that all of the handsets are in standby and not on any charger before attempting to deregister the handsets again.

You can register 12 handsets to the LS6475 base, according to page 31 of that manual for the main unit: https://cdn-media.vtechphones.com/media/p/document2/products/%7BA37C95FC-053D-4D34-B60A-EA5ED42B056C%7D/LS6475-3_UM_4_925.pdf . If you use the cordless headsets, you can register 10 handsets and 2 headsets.

These manuals can be found through the product page: https://www.vtechphones.com/pd/1603/LS6475-3-2-Handset-Answering-System-with-Cordless-Headset . The base manual is in the section under the Support & Manuals tab. The handset manual can be found from the Accessories tab. Then click on the Support & Manuals tab after clicking the link for the Handset.

I hope this helps.

your base should have power to get the handset working.make sure your base has power , may be loose connection, pull the power cord on the base and insert back and see. or try another outlet to see if any power goes to the base.

Did you pinch your phone line? We did that once when laying our floor. What a pain. We have to plug in the phone at another working jack until we fix the cord.

First de-register by pushing # and end simuntaneously. Select de-register. Then place on the base until it says that it has registered. Uniden Registering

Not sure about the refurbish issue...but have you tried to de-register the handset by holding down the end key and the # key, then placing on the main base unit to register with your system.

This fixed mine:

1/15/10

To fix this issue:

1. Unplug the Unit
2. Unplug the Phone Cord
3. Disconnect the Battery from the Handset
4. Wait 10-15 minutes… and put back together in Reverse Order
5. Connect the Handset Battery
6. Plug-in the Phone Cord
7. Plug-in the Unit

SOLUTION:

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.

My long-term experience with these phones is that occasionally, they get themselves into some kind of weird state: this is usually indicated by the flashing "searching" message.

In all cases it's been cured by unplugging the power supply AND the phone-line (both simultaneously) from the base, waiting a few seconds, then re-connecting. Normally this sorts things out, but will require you to re-set time& date (the base can sometimes still derive power from the incoming 50v line). Batteries out of handsets is a last (addtional) resort. I've very rarely had to re-register.
