    Thanks so much Silly Girl - just for caring! I stayed on hold with Uniden for almost 45 minutes but got an answer finally!! If anyone ever asks this again, you hold down the "end" key and the "#" key at the same time for about 6 seconds, and it will de-register, then put on base to register. It works!!

    Thanks again!

To De-register handset while original base present:
-Use De-register menu

To De-register handset without original base present:
-Press and hold "End" button, and while holding that, press and hold # as well.
-Remove battery
-While holding * and # replace battery, and keep holding
-You should hear one beep (let go now)
-Press right menu soft button (at top)
-Should hear one beep and Clear EEPROM/RAM on screen
-Remove and replace battery once again (no need to hold any buttons now)

(USING ANY OF THE TWO METHODS ABOVE MEANT FOR NON-BASE PRESENT, WHILE BASE IS PRESENT WILL TAKE UP HANDSET SPACE ON BASE, eg. HS1 will become HS2, while base reserves HS1 name... a base reset will be required to deal with this).

Resetting the base itself (if you have any handsets deregister them normally before this)
-Unplug power
-Hold 'Delete Messages' key while plugging power back until beep (88 or 0 messages may show)
-Press PLAY once
(To check that all went well, check to see if anything shows under ROOM MONITOR, nothing should be there)

    Legendary, if only the manual would explain how to do this.

    Doesn't mention how to reset base or tell you about de-registering handset will retain #ID in base.

Yes! To deregister units that are "out of range" or "unavailable" you hold the END and # button down for a few seconds and the phone will derigister. Place it back on the base to reregister. IMPORTANT! Push the END button first and hold BEFORE you push the # button.

    If you are not familiar with TRU8885x unites, do not use the "End" key + # key to de-register handet, unless you original base unit broke, and you are register with a new base unit. Otherwise, the base unit will think the handset still exist, and will reserve the handset ID for the "de-register" handet.

    Note: I played around with my handset with "End" key + #; then re-register with the same base unit. This cause the same handset to be taken up all 7 "handset IDs" from the base unit!!! Which at the end, I can't register the same handset no more.

    To properly de-register, please use the De-register function on the handset.

Well the top selection did not work for me and Uniden is not answering due to unusual circumstances, I initially had the TRU8885-2 that I bought a year ago and I loved then. Now we have a big house and its like the ebay user failed to deregistering before sending them. No visible damage. Does anyone know of any other magic combination to reset the security clud?? Thx Wojo

    take out the battery
    put the battery back in while holding * and #
    you should hear a beep
    then press the top right or left button
    you should hear a beep
    push talk
    put the handset on the base to register

Guess what? There is a "De-Register Handset" option in the handset menu. (I discovered it AFTER using the method above, which DID work for me.)

Hello RE; OUT OF RANGE/NO DIAL TONE I have had my telephone for 1 week now - I thought it might correct itself. I'm happy if its out of range/no dial tone and I need to de-register it once in a while, but 8-10 times a day. I dont think this is right. What is the problem? Was I sold a telephone with faults? - or, how do I fix my problem. Any help would be appreciated. My email address is [email protected] Treena Lewis

Yep the End and # key does the trick

Probably nobody here knows at the moment dear... I can give you a very lame advice, not because I think there's a good chance of it working, just so you're not left in the cold ;] Back when I had 2 identical phones with 2 different bases, we used to get mixed up once in a while and switched between the bases. I think I recall that it screwed the phones untill they were left to charge on their respective bases. This tells me that there is some sort of communication designed between the phone and the base when they are touching. Maybe what you could do is remove the batteries from the old phone for a day or two, let it reset, then place it on the base for the night. Like I said, this is a very long long shot, but I hope it works, or that eventualy someone who has seen your problem before will answer. Good luck!

Then place the handset on the Main Base cradle and follow the instruction that come up on the handset display.if the handset still does not register then most likely the base memory is full and will have to be re-set .
To re-reset the Base:- Remove any handset from the main base cradle. Then Press and Hold the Locator or find HS or handset Locator button until the IN USE light comes on and begin to flash then release it and immediately with out pause press and release it again. That will re-set the base memory. All your handset will then be de-registered and will to be re-registered.

while the IN USE light is still flashing. The IN USE light flashes for
approximately seven seconds.)

To reset:
Pick up the registered handset and then press
and place the handset back in the telephone base.
Unplug the power from the telephone base, then plug it back in.
You cannot de-register a handset if any system handset is in use.

Panasonic Phone Keeps De-Registering

This solution is for the KX-TG2356 cordless phone
The problem you are having is not that the handset is de-registering but your handset is losing the link to the main base.You said you went through 6 handsets then, the only remaining thing that could cause your problem is: A bad handset battery. This would give you all types of connection problems and the Main base.
I will begin with replacing the battery. If that does not solve your problem then the problem would be the main base

CIT310 - registration problems with the base

use the pager button, keep it pressed for about 15 seconds, and then use the register option from the phone, handset will pick up the signal. You may have to do this multiple times.



De register and re-register the handset with the base.

Handset No2 displays out of range message

Please check that you have correctly registered the second handset to the base. It may be necessary to de-register the second handset and then re-register it. "Out of range" just means the second handset is not within range of the base phone it was registered to.

Uniden Cordless Phone Model DSS7855. frequently fails to connect to an incoming call, with 'out of range' indication. The phone is less than 1 meter from the base station.

The handset/base keeps a record of who it’s registered to. The base also keeps a record of how many handsets are registered to it.

Using the de-register function on the handset deletes the handset from the base (decrements the count) and deletes the base info from the handset. All this requires that the base and handset can communicate with each other.

To remove the base data from a handset when out of range of the base, press and hold the ‘end’ button and the ‘#’ button simultaneously until the phone beeps. It will now be de-registered from the base.

However, the base will still have this handset in it’s record.

To de-register all handsets from the base, remove power and the base handset. Press and hold the ‘flash/find hs’ button while applying power. Wait for the beep and release the button. The charge light will now flash. Sit any handset in the cradle. When the flashing stops, all handsets are inhibited from connecting.

However, the handset still appears to be connected to the base unit. Pressing talk will give an ‘Unable to connect’ message. To re-register the handsets to the base, you have to de-register the handset first with the two button method.

Of interest, pressing ‘*’ and ‘#’ on the handset while reconnecting the battery is suppose to reset the handset. Doing the same on the base unit puts you in some sort of diagnostic mode. Press speaker to exit.

Uniden Tru8885-2

The older Tru8885 phones will not work with the new base unit. My recommendation would be to ebay those and then buy new ones or find replacements for your new base on ebay also.
