New Expansion Handset refuses to register with the base

I just bought a brand new MD 7090 2-line cordless phone system. The cordless set that came with the kit seems to have registered itself, but the expansion set I bought with the order refuses to register. There are no "troubleshooting" instructions in the manual ... a tragic oversight. I've followed the instructions exactly over and over again: Menu > Register > Select > Hold Page button. Open for suggestions.

    I haven't used this phone for a long time, I wanted to set it up (my telephone line won't be connected for another week). It won't recognise the base, no matter how many times I try & re-set it (I have the manual & have followed all these instructions). My question is, does it need to be plugged into a "working" phone line to do initial set up (date/time etc.)?

    I had this problem with ATT&T 82218 (bought an extra handset on Ebay). The suggested solution From the "Connecting...." handset, type *331734# then hit MENU button. Boom..... handset should now read "NOT REGISTERED" worked perfectly. Thanks.

I tried everything until I finally took the batteries out of the base unit and unplugged it. I let it set for about 10 minutes and then put the batteries back in and plugged it back in. Then the handsets would register.

Remeber when registering the handsets: (on the handset) hit "menu", "register" "select"....and then on the BASE unit hold down the "page button". Once the handset shows it is registered, hit 'OK" on the handset. The manual does not make this clear that they mean to hold the "page" button down on the BASE unit.

Hope this helps

I tried both of those solutions and neither helped.
Perhaps the handset doesn't match the base????

On the handset, you need to go into the menu, choose register, press and hold the intercom button on the handset and the page button on the base unit at the same time until it tells you that it is registered.

    This worked for me thank you!


Carolyn's suggestions above is good, but make sure you are hitting the actual PAGE button on the base, not the intercom button. This is a great phone, but the Moto user manual stinks in this one regard. :-)

I had the same exact problem, and I ended up calling Motorola. The manual says the page button on the expansion sets is the intercom button, but the page button is actually located on the base unit. When you scroll through the menu on each expansion set to register the phone, and it tells you to hold down the page button until it beeps, they're talking about the page button on the base unit. I was pushing the page button on each expansion set, and that's why it wasn't working for me. I hope that helps!

I have a phillips CD240 cordless phone, on the screen is flashing SEARCHING and wont make or receive calls.

Hi, I solved this issue this morning. "Searching" means the handset cannot find the signal from its base, and if you check your base, it's more likely than not, dead. In my case, I checked this by pressing any button on the base, i.e. answer phone etc., there was no response (although the handset seems to recharge power fine for some reason).

Therefore, I went and bought a new cheap GAP compatible (binatone 1800 Single at Comet - 14.99). I then set up the base, put it in the registration mode as per the binatone instruction. Then on the Phillips CD245 handset and gone through the above registration procedure... and Voila! It worked.

Now I have a brand new base that came with 1 new handset of its own, and 3 additional CD245 handsets which are all registered with this base. So far, the sound quality is good (no different from the previous genuine set) and they retained all the telephone numbers registered with the handset.

I don't have any high regards to binatone specifically as a brand because our last corded phone system was rubbish and died shortly after 12 months guarantee but to me it looks as if GAP compatible cordless phones have certain life-span however cheap or expensive they are (while handset seem to last much longer). Threrefore, there is more incentive to buy a cheap base new (of any make that are GAP Compatible) then connect your old handset to this base and live on 12 months manufacturer's guarantee and hopefully more. On the web, I saw some comments that are saying GAP Compatible phones and base sometimes do not successfully register each other (despite even being of the same make or brand). Obviously the users make such attempt at her/his own risk but I can confirm that the above combination worked for me.

Just for info, to do the registration successfully, the both base and handset must be in "Registering" mode. First, to get the base in the registration mode, you have to press <page> (a paging function for handset in case you cannot find where they are - usually button that says <page>or speaker with sound symbol on the base) more than 5 seconds, then the base is in the "Register Mode"(though you will hear no beep). You can then go through the procedure you describe on the handset and the handset should beep with assigned number no more than 10 seconds after it flashed "Waiting".

I hope this is helpful.


The above, however, works only if the Base is still functioning.

Uniden 2.4 GHz cordless phone won't register to base

Same happened to me. Unplug the base from power and the phone line for 30 minutes. Same for the handsets - all. Take out the batteries. Retry. After it says 'registration failed'. Leave it in the cradle. Several minutes later it found itself.

Adding a new handset

You need to register the new handset with the base.
In Global settings De-register the new handset then place it on the main base unit connected. It should then register.

A busy signal

Hi Kevin,

Sorry for being off line so long. If you have not fixed the problem already, I would try de-registering the handset 3 (from both the base and handset), then re-register it, it should re-register as HS 3, unless 1 and 2 are vacant. If that does not do it, de-register just the handset (not at the base), then re-register it to the base, it will grab the next sequencial intercom number. If it is still failing, then the handset is most likely defective. As a last resort, you can try initializing the handset and the base. Let me know how it goes. CG

You may need to "reset" the whole system1.gif. Do this by :
1 Unplug phone line, power to charger base, and remove the batteries.
2 Wait a couple of minutes.
3 Plug in batteries first, then phone line, and finally the power cord.

Then try to set the phones in the basecharger to register.

Brand new cordless handset -- no dial tone, no ring!

I doubt it's the battery. As I understand it the base works fine and the problem is only with a cordless phone. Are you using an external charger stand for the cordless handset? These phones need to be registered to the base unit. That is usually done by installing the cordless phone in the base unit but you may need to do that shortly after insalling the battery or you could have a register button or setting.
