How to register an orphaned AT&T 92370 handset to a different base station

AT&T TL92370 Phone System

AT&T TL92370 Phone System

Lightening recently damaged my AT&T Home Telephone Answering system base station rendering the 3 cordless handsets useless. I purchased an identical Telephone system that comes with 3 handsets and hoped to reuse the handsets fom the old system on the new.

Problem

The AT&T TL92370 base station can support up to 12 handsets. However as I read through the instructions on registering and deregistering handsets, it became apparent that to deregister a handset from the base station one needed a working base station to do so. The handsets once registered to a base station cannot be registered to another until they have been released from the original base station. The orphaned handsets displayed the following message

Out of range OR No power at base

I searched in vain on the net looking for a way to remedy this. I diassembled one of the hansets hoping to find a reset switch. No such luck. I was now the proud owner of 3 orphaned handsets I could not use.

Resolution

I sent an email to AT&T asking how to accomplish this. I got a boilerplate response informing me that my problem was too complicated for email resolution and to call 1-888-883-2442 to speak to a tech. I called using Skype. It took about 8 minutes on hold before I got through to a live tech. He asked basic questions and did understand my problem first time. He put me on hold and came back with the folowing code to enter into the old handsets.

*331734# followed by menu/select

The phone beeps twice, reboots and then comes back up ready to register to a new base station.

Registering to the new base station is now easily accomplished using the standard instructions.

  • Press and hold handset locator on base station until ‘in use’ light comes on.
  • Press # on the handset and the phone registers itself to the base station.

I repeated the above procedure with my two remaining handsets and now I have a 6 handset cordless system for my home.

It’s important to note that if you have a working base station you should use the standard instructions for deregistering the handsets. Each handset gets allocated a handset number by the base station, if you deregister using the special code detailed in this post then the reserved handset number on the base station is consumed and cannot be reclaimed; thus reducing the number of handsets the base station can support by 1. The special code is only for use when you have a handset that is orphaned from a lost or  non-working base station.

How can you deregister the AT&T TL7610 headset without a base (broken)?

THANK YOU! I just had the *exact* same issue with lightning and this fixed my orphaned handset! Kudos!

Thank you!!! I just bought an AT&T SL8 series handset (SL80108 for an SL82118 base) which, once fully charged, only displayed “Connecting”. Resetting the base by unplugging it for 15 seconds did nothing. Unregistering the existing handset did nothing.

But this reset code worked! And you don’t need to wait for a base to do it.

Note: You must charge the handset enough so that it displays “Connecting” (for the SL series) before entering the code, “*331734#” followed by the Menu/Select button in the center of the scroll up/down circle above the keypad. As mentioned above, it will beep twice before rebooting, and the display will now say “Not Registered” or “Press Hndst Loc 4 Sec on Base”. If you now put this handset into the holder on the base and press the Handset Locator button for 4 seconds, the handset will be registered with this base as “Handset 2” (if this is your 2nd handset).

Many, many thanks for posting this unique and previously undocumented solution.

How to register an orphaned AT&T EL42208 handset to a base station , i did the instruction as u said but it didn’t work, any help ????

4 11 2011
jpwhitehome

I believe procedures may be model specific, therefore the instructions don’t apply to your unit. I found the information I detailed in my post by calling AT&T technical support. I suggest you do the same.

This post may be too little to late, but to manually de-register the TL7610 head set press the following on the head set one at a time:
– Volume up
– Mute
– Volume down
– Mute
– Volume up
– Volume down
– Mute

This was awesome….. and it worked for my ATT CL82309 phones.

I have about 10 of these cordless phone systems in my stores. I got three handsets with each, but we only use two, so there’s lots of spares. But whenever I tried to use a spare we could never get it to register…

THANKS!!!!!

THANKS for your insight and expertise. My dog destroyed one of my original handsets so I purchased another one on eBay.

I’d called AT&T and they told me that there was no way to add or register a handset. While on hold, I came across your blog and began implementing the procedures.

Once the tech found out that I knew how to do it he was suprised (disappointed) but helped me through the process. Now I have two handsets working perfectly. THANKS again

FANTASTIC! You’re a life saver! Spent 75 buckaroos on a slightly used AT&T 4-handset set to expand on main level and basement – only to find the “new/used” sets would not “register.” THANKS A MILLION for this info. Without it, I’d have a $75.00 box of useless junque. – Johnny Long – NC

Was really excited to find this post, as I just bought 3 handsets at an estate sale. Unfortunately, the code doesn’t work for me. I guess I’ll have to talk to ATT.

Bless you for posting this! I had the exact same issue (who knew lightning traveled through phone lines?) with an AT&T SL82218, and your post saved just as the frustration of trying the process in the owner’s manual for the third time.

My phone doesn’t even look like the one in the picture (in fact, I couldn’t find my manual or a model number), but this procedure WORKED! Thank you so much!

Thank you for posting this solution! I had the same lightning issue with my AT&T CL84100 and this worked like a charm! Having to buy 6 replacement handsets would have really been depressing – you made my day!

Thanks-a-million. After trying the manual and on line I discovered your solution. It worked great on my orphaned handset from a 2 phone system onto a 3 phone system.
I now have a 4 phone system AT&T CRL 82412 from a CRL 82312 system.

This is awesome! I have an AT&T SL81108, bought an SL82218 (which looks identical) but it would not de-register even on the base. This code de-activated the hand-set and I was able to add it to my existing base. Thank you

28 12 2013
CMW

Thank you SO much. Worked like a charm on my CL84100 (especially after I noted that I had to press the star key before the numbers!). Thanks for saving me from wasting money and resources on new handsets!!

Thanks so much for posting – hard to believe it was so difficult to find this but thanks to you I’ve saved 2 old handsets from an early grave.

EL52300 handset. When I press menu/select there is no option for inputting a code number, just a menu of choices starting with “Play messages.” What am I missing?

27 10 2014
jpwhitehome

If you are able to play messages the handset is paired to the base station and there is no way or need to enter a code.

5 11 2014
Ted Pirsig

Actually, it’s not connecting with the base. Even though it says “play messages,” if one tries to do so, it then displays “No power or base out of range.

I called AT&T tech and they said this model is non-expandable. When I asked about using the old phones as *replacements* — not expanding, just replacing — she said it wasn’t possible. I said “you mean to say, the phones are assigned to one base unit at the factory, and can’t be changed?” and she said “That’s correct.”

6 11 2014
jpwhitehome

That’s a shame. It maybe worth calling again to get another tech. Maybe midweek during the day.

Hi, just wanted to chime in after going in circles around this myself for a while. I just resetted a model EL52300 using the steps laid out by Thomas Moffit. Just make sure to hit menu/select and enter *7890# fast. If you take too long the phone does nothing. If you do it fast enough the TEST menu will appear.

18 01 2015
Danny

J.P. and Thomas: Thanks for your posts! It’s awesome to find this here when AT&T doesn’t post it any where. This worked for an EL52333 set that I wanted to move one handset to another system, without resetting everything. Kudos!

14 07 2016
LAL

Our EL52300 base was destroyed(?) by lightning. I’ve now reprogrammed those old handsets to our new EL52200 base using your instructions. AT&T told me it couldn’t be done. Thanks so much.

25 05 2017

Just used this *7890# method to unregister my EL51203 handset and register to an EL52303 base. Thanks so much!

15 02 2014
John

Me too. CL84100 worked great. I work business hours and was unable to call att during their non customer friendly hours. I had to replace my base unit after a power failure produced a message “load eep def”. No reset corrected this. So I bought a used base from eBay. Then the four handsets could not be registered. The code worked great. Thanks again for doing the footwork with att. Really appreciate it. I searched for a week until I googled “reset” instead of default. Thanks again….

Excellent results! The old registration was cleared and the new (re)registration took without problems. Thanks for the help.

23 06 2014
Mollie

Have massage ‘put HS on base to register’ after entering the code, so something worked. However, the next step is to ‘press and hold HS locator on base until in use light comes on’.. I do not see any bottom on the base that says ‘HS locator’. What am I missing?

23 06 2014
Mollie

Figured it out! Incase someone else cannot find the ‘handset locator’ button, it is behind the handset on the base…need to take handset out in order to see it. So glad I found this info…very helpful! Thanks!

Worked for me:)) Thank you so much! I love when my persistence pays off. LOL

Thank you for posting this “magical” cure! I have spent several hours trying to find this solution on the ATT telephone web site and in the manuals without finding anything. It worked on my CL80111 like a charm.

10 08 2014
Santiago

Excellent, thank you! I used the procedure that Thomas Moffitt details for model EL52313 and worked very well. Then, to register http://cdn-media-att.vtp-media.com/media/p/document2/products/%7B3B3FA291-E443-4DF1-AC8B-2E462D094EF2%7D/EL52313_UM_4_530.pdf on page 67.

I am translating the solution to Spanish in order to make this easier for other Spanish speaking guys like me looking for the solution:

SOLUCION AL PROBLEMA DEL MENSAJE: ” OUT OF RANGE OR NO PWR AT BASE” EN TELEFONOS INALAMBRICOS AT&T MODELO EL52313

Presione el botón Menu/select
Presione *7890#
Con las flechas vaya a “test handset” y presione Menu/select
Con las flechas vaya a “next page” y presione Menu/select
Seleccione “register clear” y confirme presionando Menu/select nuevamente
Aparecerá “ok”, presione el botón de colgar una llamada off/cancel
Desconecte la batería por 15 segundos y vuelva a conectar
El teléfono tendrá el mensaje “To register HS… …see manual”

Para volver a registrar teléfono solo necesita colocarlo en la base (en la base principal, no en el cargador de cada equipo). Aparecerá el mensaje “Registering” y luego “Registered” en pocos segundos y sonará un tono de confirmación.

Repita el procedimiento con cada equipo que tenga el mensaje “out of range or no pwr at base”.

24 02 2015
huguetpj

Es importante destacar que la secuencia menu/select *7890# debe hacerse rapido. Si se escribe muy despacio el telefono no hace nada.

Once I managed to follow your directions for EL52303 they worked perfectly!

You have provided a very needed article.
Lightning killed the base of my CL82301 system so I thought had 3 useless handsets. Tried the *331734# followed by menu/select and now I have 3 working handsets.

THANK YOU! THANK YOU! THANK YOU! This code [*331734#] also worked on AT&T Model SL82218. Looked everywhere and this is the ONLY place with a solution. you da’ man

I had exactly the same thing happen to me – lightning strike fried my AT&T base unit. How funny! Bought “same” unit on EBay, but ended up with a different base number and three useless handsets. Code worked like a charm. Now have four set system. Thx.

Would you please give me the entire procedure to deregister my AT&T TL8802 handset. The handset has no menu/select button.

RexG

Lightning strike here, too. Old base was EL52309, new one is 52300. The 331 code process will reset my old handset, but it won’t register on the new base. I even get a message on the old handset to hold the find handset on the base for 4 seconds, which seems to make some connection but the handset doesn’t register.

taco

You are the MAN! Thanks so much! Bought three AT&T 4-phone sets at Costco (CL83464 handsets). The base can handle up to 12 handsets. After I setup the first set, I used your code and now have 12 handsets on the same base station. Cooooool!

Thank you SO MUCH for the info as it was exactly what I was looking for. I was given a phone from someone who was discarding their att three phone system and could not figure how to get pass the out of range error message. The coding you listed did the trick. Thanks again!

mrome

Wow! I just went through every AT&T support info and couldn’t find a solution. I just bought a pack that has all the looks of a refurbished one, both handsets showed “Out of range or base out of pwr”, impossible to find a reset info other than unplugge the base. Thank you so much for sharing this code!

11 01 2016
ToniB

I am so excited! I read your post. But the code didn’t work. Called the tech number you posted, and immediately received the code specific for my phone set. She walked me through the whole procedure and now I can use my old handsets that were going to be useless after the lightning strike. I was about to throw them away. Thanks goodness for people like you.

11 01 2016

Glad my blog article lead you to a solution!!

If you have found out codes for another model, do mind sharing the phone model and codes to reactivate on a new base? I can add an addendum to my article here to help more people.

Thank heaven! I have the exact same issue- power outage killed everything on the base station but the charging feature. It seemed ludicrous to me that you couldn’t reset it from the handset.

Thank you! I’ll be attempting this when I get home tonight.

Great posting! Lightening strike damaged the SL82318 base years ago and I needed to replace a handset recently. It was helpful to couple the posting with #5 Bob’s response. I thought you needed the old phone base, but it was not needed. When I tried contacting ATT, there was no way to talk to a human. Faith in humanity restored – thank you.

texasbuc

Thank you so much for this! We have a brand new phone set and I was dreading calling support. The two extra handsets would not register with the base. The manual says to place them in the base and if they won’t register to unplug the base and pull the battery from the handset. But then I noticed that the in-use light was not coming on on the base when trying to register. A google search lead me here and I tried the instructions:

Press and hold handset locator on base station until ‘in use’ light comes on.
Press # on the handset and the phone registers itself to the base station.

and it worked instantly. Awesome!!!

I have a collection of 12 CL82109’s, 309’s, 409’s, 509’s, 359’s and 659’s. This procedure worked like magic. I especially like the pressing “#” in the registration process. Makes things a lot faster and easier.

Perfect! This works on the AT&T CRL80112, handset, too. Also, the only way I could get it to register to the base station was following your method. The registration method in the manual was repeatedly followed by “Registration Failed.”

This fix worked with an ATT CL84102 that replaced my dead ATT CL84202 (difference is how many cordless phones come with the system). My older system had three phones stuck in “Out of Range OR No Power at Base”. I wouldn’t have thought the same reboot code would have worked across the years and differences in models. But since it was AT&T, I gave it a shot.

Thank you for posting this!!!

Alby Keneth

This fix also worked with a new ATT CL84365 from Sams Club. Pairing this orphan to the basewas simple as pie…

I have a different model and found how to derigister for it:

DeRegister Handset AT&T El52300

1. Hit menu/select and very quickly input: *7890# (don’t forget the * in front. This is 6 digits!)
2. Use VOLUME (large Button) up down until you see TEST HANDSET
3. Click on MENU/SELECT and go down the list using LARGE VOLUME button until you get to: REGISTER CLEAR. Confirm by clicking MENU/SELECT
4, When it displays OK< press and hold HANG UP/CLEAR/OFF Button
5. Unplug Battery for 15 seconds and plug back in
6. Handset is now unpaired so now you have to register it
7. On BASE, press HANDSET LOCATOR until IN USE LIGHT displays (about 4-5 seconds)
8. On Handset, press the # button

21 01 2017

Thnaks for sharing this info, I hope this helps others with this particular model as well!

dan0neill

Thanks so much for posting this, and thanks to the AT&T tech who gave you the solution, and to you for the patience to get it. As another commenter has said, it works also for the SL82x18. When my base suddenly died (voltage surge?) I bought a single-handset base, SL82118, from an Amazon vendor, but then found, as you did, that I could not de-register my six old phones without having its original base to do so (but it was dead!). Your secret kill code worked perfectly, allowing me to register them to the new base.

Btw, did you notice that the code is essentially “*DE-REG#” but with the “-” replaced by a 1?

25 02 2017
Stephan Strebl

Thank You! You deserve a big sloppy kiss (from my dog…)
I own the at&t CL84200 DETECT 6.0. Recently I purchased two more handset from an Amazon seller which of course came up with the “out of range…” message. Since the model number on the inside of the handsets was different, CL84250, I was concerned they might be incompatible. After some investigation, I knew they would work if only I could deregister them. Ready to take them apart and seach for a physical reset button, I did one last search and found your page. Of course it worked! at&t spent a gazillion dollars developing this chip-set and is using it in all of their phones. I also wouldn’t be surprised, if different models of bases and handsets could be successfully paired even of different year models (maybe not all features would work…?).

Thank you agin for your diligence and for SHARING!!!

Mucho thanks for the info / code. I purchased a couple of extra handsets at a charity sale, no base unit, to add to my existing system. Worked like a charm.
