Hi, I have a DECT2085-3 base with 3 handsets. I would like to add another handset. I bought two used handsets and would like to register them to my original base. One handset says DECT2080-5 inside and the other says DECT2088-2. Both handsets charge fully, however so far I have been unable to register them to the base. I can press select/menu on the handsets and get a list of options, but the middle button does not scroll up and down between the options. At first I thought one might be broken, but since both handsets have the same problem, I am thinking I need to do some other command. I can press select/menu on the handset 3 times and go from"handset setup" to "select base" to "auto". Then on the base, I can do select/menu, "register handset", and get a message that says "registering handset". I've tried putting the handset in the base, or just leaving it nearby. In both cases, after a bit the base says "registration failed". I think I need to de-register the handsets. When I hit the hang-up key and the number key at the same time and wait 5 seconds, I get a menu with "de-register handset" but can't scroll up and down. Hitting the select button at that point brings me back to "out of range". I can't scroll down to "base unavailable". So I think I need to de-register the handset, but without the middle button I can't get to that command. Can you suggest a way to proceed? Thanks.

    Uniden suggested to reboot the phone by disconnecting the battery, holding down the Star and Pound key, and reconnecting while holding down both keys. I was able to clear the phone number cache, but the central toggle button still doesn't work. Uniden tells me the phone is broken beyond repair.

Vtech cordless handset CS6209 will not connect with CS6229-2 base


Yes. The'old' handset must be de-registered from its
original base and then registered to your base.

NOTE: the CS6229 handles a maximum of 5
handsets. If you have a handset displaying
"Handset #5" then you have a 'fully populated system'
even if you actually have only one or two handsets.

You will need to clear each handset ( I ) then clear
the base of all registrations ( II ) before re-registering
each handset ( III ) up to the maximum of five.
=====================================
( I ). First, to de-register a handset ---

0. Start by taking off the battery compartment cover.

1. press [menu]
2. scroll up/down to "Settings"
3. enter * 7 8 9 0 #
4. scroll down to "next page", press [select]
5. scroll down to "Register Clear?", press [select]
6. display asks "Confirm?" or "Register Clear??",
press [select]
7. display reads "Ok" and chirps, press [ off ]

8. UNPLUG THE HANDSET BATTERY
(this is why the cover was off)

9. Wait ~30 seconds, re-connect the battery &
replace the cover

10. display reads "Not Registered"
===============================

( II.) To clear the base of all handset registrations
( if needed, else skip ahead to ( III ). )

1. press [Find Handset] on the base and hold
past ~4 sec when the "In Use" lamp lights, at
about 10 secs the "In Use" lamp will begin to
blink. 2. release the [Find Handset] button momentarily,
then briefly press it again. After a moment,
all handsets that were registered to the base
(if any) will display "Not Registered" and be
ready for fresh registration ===============================

( III.) To register each handset to the base:

1. press [Find Handset] on the base and hold for
~4 sec until the "In Use" lamp lights.
2. press # on the handset and set the handset into
the handset cradle on the base
3. within 30 seconds or so, the handset will either
chirp and display "Handset Registered", then
"Handset #x" or it will say "Registration Failed".

NOTE: the battery must be well charged prior to the
registration process, a weak battery may cause a
"Registration Failed". Charge the battery for a
few hours and try the registration ( III ) again.

===============================
Good luck !! --

I am trying to replace a handeset on my E5640 answering system. I have followed the procedures to deregister the existing handsets but it will not accept the base code for the last one. The handset I am...


  • Your telephone can accommodate up to four cordless handsets. You can add new handsets (Model E560-2, sold separately) at any time, but each must be registered with the base before use.
  • The handset provided with your telephone is automatically registered as Handset 1.
  • Additional handsets will be assigned numbers in the order they are registered (2, 3 or 4). You can register a maximum of four handsets.
To de-register all handsets
• Unplug the power supply from the base unit.
• Remove all handsets from the charge cradles and base.
• Plug in the power supply while pressing and holding the HANDSET LOCATOR button.
• Continue pressing HANDSET LOCATOR until the IN USE and CHARGING indicators are lit (this could take up to 10 seconds).
• Release the HANDSET LOCATOR button.
• All handsets will display: ENTER BASE ID: XXXXXXXXXX
Once the base indicators turn off (up to 30 seconds), the handsets have been de-registered from the base, and can now be re-registered.

To re-register a handset:
• Make sure your handset batteries are properly installed and charged.
• Your handset will display "ENTER BASE ID".
• Enter the 15-digit Base ID number from the bottom of the base unit.
• Press SELECT to accept the new code and complete re-registration.

To re-register a handset to a new base unit:
• Make sure your handset batteries are properly installed and charged.
• Unplug the old base unit. Your handset will display "SEARCHING...".
• Install the new base unit by plugging it into an electrical outlet and phone jack.
• Press and hold the SELECT key until the handset displays "ENTER BASE ID".
• Enter the new 15-digit Base ID number from the bottom of the new base unit.
• Press SELECT to accept the new code and complete re-registration. The handset is now registered to the new base.

Can I use handsets from another DCT 748 unit to expand my DCT 748


Short answer:
No. This model of phone can only support 4 handsets. If you need more than that, you will need to have a second base unit.

Detailed answer:
One of my handsets went bad, and I just bought complete DCT748-4 package from a seller on eBay for a very good price. This set was used, but in very good condition. I didn't need the whole set - just one handset - but like I said, it was a good price. Anyway, I began by telling my old base unit to de-register handset #2 (the failed unit). However, I then found that I could not register the "new" handset with my old base unit because it was already registered to the "new" base unit. So, I first had to apply power to the "new" base unit and de-register the handsets. Then, I placed one of the "new" handsets onto my old base unit, and it said "Handset Registering ..." and registered just fine. Just for the fun of it, I placed one of the other spare handsets into my old base unit. It said "Hanset Registering ..." but then it beeped and said "Registration Failed." This is because I already had 4 handsets registered to my base, and the base can not handle a fifth handset.

Programming old handsets to a new base


Cancel the old handsets registration at the previous base unit if desired.
For additional handsets, you must register each of them at the new base unit. Only one handset can be registered at a time. A handset will be assigned anextension number at registration.


Make sure the base unit and the other handsets are not being used. Program the same way as the extra handset you bought.

Registration must be completed within 1 minute.
