Handset purcahsed used for att cl82659 cannot be deregistered. any advise

SOURCE: OUT OF SERVICE MESSAGE

Hi J,

Apparently that one from Ebay looks nice but has issues (not uncommon). If you took it out of the box, charged it fully and its has garbled audio, then the handset or the base is defective, or both, but at least at this point you can get a handset to "communicate" with the base and the "in/use light turns on, when you try to access a line,correct? . If you get the "out of service" message when trying to "move" the "ebay" handset to the other base, it sounds as if the base station and handsets are "coded" and were married together at the factory and one handset won't interchange with anothers base. However, try this before you go the repair service route, or roll the dice with another fine product off EBay :). Unplug and power down both bases, the one from Ebay and your old one. Take the Ebay handset and set it in the charging cradle of your old base. Power up and wait three minutes. Plug dial tone in and give it a try. If it still says "no service" , and won't light the "in/use" light when you try to use it then it won't work with your base, or/and your old handset you lost is somewhere near and is still communicating with its base. Now if you lost your handset weeks ago, then the odds that it is still alive are pretty slim. But I have heard handsets in the warehouse beep for days til their battery dies. You can google cordess telephone repair for service. Good Luck. CG

The process is called "Registering."

From another fixya post:

1. Make sure to charge the handset battery pack at least 12 hours.
2. Using the soft keys on the base located below the base screen, press MENU.
3. Use the up or down arrow keys to select DISPLAY BASE ID.
4. Press OK. The base screen will display the 15-digit Base ID
code for about 30 seconds, then the unit returns to the idle
screen. Write down the Base ID code on a piece of paper.
5. At the cordless handset, use the soft key to select NEW.
6. Enter the 15-digit Base ID code using the number keypad.
7. Use the soft key to select OK. The screen displays PLEASE
WAIT!.
8. After about 45 seconds, the screen displays FOUND BASE. If the handset displays BASE BUSY TRY LATER, the base is in
use.

Hi well you do indeed have a problem, and you are correct in that yes that non-functioning handset is the one causing all the problems as it cannot be "De-registered".
Please find below your user manual, now download and have a look in the manual to see if indeed there are any "Reset" buttons on the base station, sometimes on some models there is a reset button that when activated, ie: held in for a few seconds while removed from the power, this will flush out all the old settings and allow one to reprogram it all again, this no doubt will sort out you problem. Sometimes it is a series of buttons that you hold down in an order to effect the same thing.
Otherwise you are going to have to fix that "bad" handset and use it to do it?
