Re: deregistration

I'm not sure exactly what you're trying to do, but here's the rundown of what I can get from your post.
To register (assuming the phone is not currently registered): place the phone in the main base cradle.  It should automatically register itself to the base.
To unregister:  I can't tell you exactly how to do this because I don't have my phone sitting infront of me, but I know that it is in the main menu on the phone.
Using the end call/pound key: Pressing this combo and holding for about 5 seconds (possibly much more - it's taken me 10 seconds before) will THEORETICALLY let you reset the base.  I have never gotten this to work before, but the menu once you hit this should be fairly self-explanatory.  The reset I believe resets the base to factory, and unregisters all phones.
Hopefully this helps.  If not, repost and I can most likely help you out (I've got the same phone).  Best of luck!

Handset display says "Connecting" I can't deregister. How can I get the handset to display "not registered"?

The procedures to deregister are, of course, specific
to each make and model number of cordless phone.
All of them are a LOT more involved than simply
removing the battery.

For some AT&T, VTech, Uniden, & GE model numbers
you might try the following:
For many AT&T models it is simple:
1. When the handset says "Connecting..."
enter *331734 [menu]
it will soon (chirp) and display "Not registered"
For many VTech models it is a bit more involved:
1. Start by taking off the battery compartment cover.
2. press [menu]
3. scroll up/down to "Settings"
4. enter * 7 8 9 0 #
5. if display reads "Test Base",
scroll to "Test Handset", press [select]
scroll to "next page", press [select]
6. scroll to "Register Clear?", press [select]
7. display asks "Confirm?" or "Register Clear??",
press [select]
8. display reads "Ok" (chirps), press [ off ]

(this is why the cover is off)
10. Wait ~30 seconds, re-connect the battery &
replace the cover
11. display reads "Not Registered"
For many Uniden models:
1. Press and hold the [END] and [ # ] keys at the
same time, after a few seconds the display reads
2. "System Reset, Deregister Handset"
3. scroll to "... Base Unavailable"
press [SELECT]
4. Handset (chirps)
press [END]
5. display reads "Not Registered, Place in base..." =====================================
For some GE models:
1. press "program[mute]"
2. scroll to "Handset Setup" press "program[mute]"
3. scroll to "Deregistration" press "program[mute]"
4. scroll to "Yes" press "program[mute]"
5. display reads "Not Registered"

Once you have the handset displaying "Not Registered"
you can follow the User's Manual instructions to register
the handset.

The model number for your cordless phone is shown on
a small sticker underneath the battery in the handset --
enter this number at to get a free
copy of the User's Manual if you need it.

Good luck!

I bought some handsets but they were registered to another base. How do I deregister without the base

First, select Deregister HS from the main menu. Secondly, press the red phone button and the # key simultaneously for about 5 seconds to finish deregistration. You will then see a message telling you to place the phone in the cradle of the base unit to register it to your unit. An "operation complete" message will confirm that the handset is now registered and ready to use. Good luck.

Hi There.. Lost instructions..wanted to know how to change the handset setting/line settings.. want to change handset to different base ?? Hopefully you can assist? Thanks

First, you need to de-register the handset from the current base. Then register it to the new base. On the handset, press Menu then navigate (up/down arrows) to Handset Settings and press OK. Next navigate to Registration and press OK.

For deregistration: navigate to Deregister then press 3 3 5 . Then select which handset to deregister (1-6) (the handset number will flash when it is selected) and press OK. Select Yes and then OK. When the deregistration is complete, press OFF.

For registrations, navigate to HS Registration then press OK. Then move to the base and press and hold the Locator button until the registration tone starts. If all the handset ring, press the locator button to stop the response and start over. Within a minute and a half of the registration tone starting, press OK on the handset and wait until a beep sounds and the symbol on the screen stops flashing.

The user's manual is available here: . It's in the tab marked Operating Instructions. This will provide additional setting information.

I hope this helps.
