How do I deregister my handsets on my VTech 2656

Unfortunately, the old handsets may not be compatible with the new base. The DS6251-2 base only communicates with the DS6250 accessory handset. See the accessory list here: https://www.vtechphones.com/store/pd/4158/DS6251-2-2-Line-2-Handset-Cordless-Phone-with-Answering-System-Smart-Call-Blocker . If the old handsets have been deregistered from the previous base unit, place a handset in the cradle on the base. Wait to see if the handset is registered. Alternately, press and hold Page until you see Registering. Release the Page button. Then press Quiet/# (below 9) on the handset. Wait for the handset to be registered.

To deregister handsets from the DS6251 base, press and hold Page. You'll see Registering Please Wait followed by Deregister all devices? At this point, release the Page button. Then press and release Page or the soft key for Yes.

I hope this helps. These are shown in the manual for the accessory handset. The manual is on available on the accessory handset page: https://www.vtechphones.com/store/pd/4184/DS6250-2-Line-Accessory-Handset-for-DS6251-series-phones .

De-register the base station by holding the find handset button for 10 secs ... to reset/deregister a VTech Dect 6.0 handset without the old base

To deregister all handsets, with all handsets in standby, press and hold the Find Handset button on the base for about 10 seconds (or until the In Use light turns on and flashes). Release the Find Handset button. Then press and release the Find Handset button again while the In Use light is blinking. (You have about 5 seconds.) Wait until the process is complete. You should see the registration message on all handsets.

If the deregistration process fails, you can try resetting the unit from a registered handset. Pick up the registered handset that is on the base. Then press Talk/Flash button and then Off/Cancel buttons. Then try again.

The manual for the additional handset, CS6409, that is available for the CS6429 has the de-registration procedure. That manual is available from the product page: http://www.vtechphones.com/products/product_detail/1604 . Click on the Support & Manuals tab. The direct link to the manual is http://cdn-media.vtechphones.com/media/p/document2/products/%7B9B67F082-6CC0-48CC-B7F2-23C65B10A4F1%7D/CS6409_UM_V3_20141202.pdf .

I hope this helps.

Maybe this might help.

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:

1) Grab any working handset which is registered to your base (so HANDSET #2 or #3 in your case)

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.

This worked for me after lots of digging....If you have already tryed reregistering your handsets and can only get two-or three to work try this and deregister them and re-register. If your base model number is vt2431: Take the handset out of the base, press **335782 on the dial pad of the base. (do not have the line active or anything , just put the (2) stars and 335782 in (no spaces) on the base unit. This will de-register all of the handsets at one time. Then just re-register the handsets...

Was looking for this for awhile as well, if you held onto them like I did the wait paid off, they must have put this up since I last looked.
