My headset is broken and I want to deregister it

You can deregister all of the handsets and then register each one again for the LS6475-3. Make sure that all of the handsets are out of the base and all chargers and that the phone and all handsets are in standby. Then press and hold Find Handset on the base. When the In Use light begins to blink, release the Find Handset button. During the seven seconds that the In Use light is blinking, press and release the Find Handset button. Wait for the deregistration process to complete (about 10 seconds).

If the process fails, you may need to reset the base. You can do this by unplugging the AC power cord to the base or by picking up a registered handset and pressing Talk/Flash. Then you can try again. These directions are on page 5 (page 8 of the PDF) of the manual for the LS6405 handset. The direct link to this manual is https://cdn-media.vtechphones.com/media/p/document2/products/%7BD6DAD9B0-4C1A-4882-93D9-04124A59B629%7D/LS6405_CIB_V5_20160805.pdf . Then check that all of the handsets are in standby and not on any charger before attempting to deregister the handsets again.

You can register 12 handsets to the LS6475 base, according to page 31 of that manual for the main unit: https://cdn-media.vtechphones.com/media/p/document2/products/%7BA37C95FC-053D-4D34-B60A-EA5ED42B056C%7D/LS6475-3_UM_4_925.pdf . If you use the cordless headsets, you can register 10 handsets and 2 headsets.

These manuals can be found through the product page: https://www.vtechphones.com/pd/1603/LS6475-3-2-Handset-Answering-System-with-Cordless-Headset . The base manual is in the section under the Support & Manuals tab. The handset manual can be found from the Accessories tab. Then click on the Support & Manuals tab after clicking the link for the Handset.

I hope this helps.

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!)

try deleting all headsets using primary headset (marked with no.1): 4-base/8-deregister/default pin '0000' and register them again using each headset (3-headset/8-register/same pin). it worked for me.

I had the same problem!

What you need to do is hold the "end" and "#" key for 5 sec, which will deregister the headset then all you would have to do is place it back in the base for it to registered again.

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.
