Deregister cs-6629 handset - Vtech DS6151 Cordless Phone

The following is for the model ATT 5830.

Enter the following sequence on the base station including the * symbols.
**335782

This will deregister all handsets associated with that base station. Handsets can then be added back into the system by entering the base station ID into the handsets one by one. The base station ID is on the bottom of the base station itself.

Called the manufactuer.... To do this enter on the handset you want to deregister:

*331734# and press (Menu Key# 1 - top uppermost left button that is unmarked).


This will put the handset back into the register mode.



Hope this helps,

To de-register HANDSET #1:

2) Press and hold the "END" + "#" key for 5+ seconds (wait for it to beep)

3) Choose the "Deregister HS" menu option

4) Pick HANDSET #1 as the handset ot de-register (since that's the "phantom" registered handset)

5) Once de-registered, you can de-register handsets #2 and #3 directly from each handset's "normal" menu interface (i.e. press "Menu", choose "Deregistration")

6) Thereafter, if you re-register your handset, they should start at HANDSET #1, then #2, and so on.

The "END" and "#" key combination can be used for several purposes:

1) If wanting to use an ALREADY REGISTERED HANDSET on an alternate base, and if if the INITIAL BASE isn't available to deregister the handset:

1a) Press "END" + "#" until it for 5+ seconds (wait for it to beep)
1b) Choose the "Base Unavailable" option
1c) That'll deregister the CURRENT HANDSET so that it can be re-registered on ANY base.

2) If a BASE has a handset registered to it which you no longer want registered but the registered handset is missing or broken:

2a) Grab another WORKING handset which is properly REGISTERED to the BASE in question
2b) Press and hold the "END" + "#" key for 5+ seconds (wait for it to beep)
2c) Choose the "Deregister HS" menu option
2d) Pick the REGISTERED HANDSET # to de-register. (Every other registered handset EXCEPT THE ONE YOU'RE ON will appear in the list!)

If the handset has previously worked with the base - press the hangup button and the # key at the same time on the handset for five seconds and follow the prompts to deregister the handset. (System reset - deregister HS - which handset) It will tell you that the handset is deregistered. Then put the handset onto the base and it will register the handset.

One has to completely deregister all handset by pressing end and # keys together till complete de registration is shown on handset screen. if the de registration is not done as above stated method the hand set will not register will show connecting on hand set screen.

Hope This Helps - It worked for me

I have a Panasonic KX-TG6700 base unit and KX-TGA670B handsets. We had a similar problem where we were no longer able to deregister the handset using the handset itself. We wanted to be able to use that slot that the broken phone was still occupyng. The solution that we found in the manual online was to hold down the intercom button for 3 seconds until the "in use" light turned on. Then press and hold the number of the extension you want to deregister until it beeps. At this point the base unit has freed that extension.
