How to remove Uniden handset from base

Hi,

The CEZAI2998 does allow up to a total of 6 handsets, but your issue is that the EZX290 handset is not one that will function with that system. I have listed below the compatible handset models for that Uniden unit and as you can see the EZX290 is not supported. Sorry to be the bearer of bad news, hopefully you can exchange it for a compatible handset. Good luck!!

Compatible with select Uniden handsets
Including models DCX150, DCX200, DCX210, DCX290, DCX300 and DWX207 for wide-ranging compatibility.

A search of Uniden support only said to call 1-800-297-1023 with handset registration issues. The rep picked up quickly and walked me through the reset procedure. Here it is step-by-step:

1. Remove battery
2. Hold down the * and # buttons and reinsert battery. You should hear a long beep. If not retry. (This is a bit awkward but hold the handset upside down and it's workable)
3. Screen will be blank. Immediately press the right soft menu button.
4. Screen will report that EEPROM is clearing and then state EEPROM Clear Ok
5. Remove battery (yes again)
6. Reinsert battery (this time there's no need to hold down any buttons)
7. Handset will reboot with Welcome screen and then state that phone must be registered (this is the status a handset should be in from the factory)
8. Place handset on base and it will register as normal

You need to register the new handset with the base.
In Global settings De-register the new handset then place it on the main base unit connected. It should then register.

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

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)

Here is a link to the uniden manual link and an excerpt from the manual section which deals with your problem :

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 :)

Here is a link to Uniden's site, and on the right side of the page, there is a link for a download manual pdf and helpline

also worth checking if any buttons are stuck, or if the handset is set to pulse rather than tone mode, or if it has had a tumble or knock, possibly the keypad connector has come loose .

Hope this helps.
