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!

CANON IR2520 ERROR E000000

Base el5200 will not reconize new hand set

To deregister the new handsets from their old bases and re-register
them to your base, try this for each new handset...

1. When the new handset says "Connecting..." and goes nowhere
else, enter *331734 [menu] and it will soon beep and display
"Not registered"

2. To register the new handset to your base: on the base press
the "Handset Locator" button and hold it until the "in use" light
comes on ( ~ 4 seconds ), then release the button and set the
new handset into the base phone cradle. After ~ 30 seconds
it will beep and display its "Handset #" (next in sequence).

3: Note: the base has a limit to how many handsets it can handle,
I believe it is five handsets maximum for the EL52300.

If your system was fully populated ( ie, a handset is already # 5 )
you will have to clear all the handsets from the base and
re-register them in sequence ( it is the only way to 'rescue' the
places occupied by the lost handsets ).

To clear the base of all registrations:

1. Press and hold the the "Handset Locator" button until the
"in use" light lights and then starts to blink ( ~ 10 seconds ),
release the button -- then press it again briefly while the "in use"
light is still blinking.

2. The base will beep and all handsets will display
"Not Registered"

3. Follow the instructions above for each handset in turn: press
"Handset Locator" ~ 4sec ( in-use light on ), set handset into
the base cradle, etc.

The manual is available from:
but does not describe these procedures.

Good luck !

My cordless phone says "to register see owners manual for help" How do I get the phone working, it is a uniden DECT 6.0 Model DECT 1588-2

With the phone in standby, press MENU/SELECT on the base.
Move the cursor to select the Register Handset menu, and then press MENU/SELECT. Handset Registering will appear.
On the handset, press and hold # until the handset beeps and displays Handset Registering.
When the handset has registered to the base, the LCD will display Registration Complete then show the handset ID number.
If the display shows Registration failed, repeat the process again.
Note: If a handset has ever been registered to a base, reset the handset before you register it to a new base

I have a Uniden DECT 6.0 phone set. I damaged one

On the base, open the menu and select Register Handset. The display should say Handset Registering.
On the handset you want to register, press and hold # until the handset display says Handset Registering (about 2 seconds).
DSL filterTelephone cordTelephone wall jack
In about 30 seconds, the handset display should say Registration Complete. Press Talk/fl ash and make sure you get a dial tone.
you don't hear a dial tone

Making sure the handset is fully charged, then start over at step 1.

Cannot get phones to register to individual base

press and hold the # key on each handset while it is by the main base

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.

Just bought an additional handset for GE 27951 expandable 6.0 DECT Cordless. I press and hold the Page button for 5 seconds but the new handset will not register. Error keeps occurring "no base."

This exact thing happened to me. Same model number. No matter what I did, the new handsets would not register.

The solution? Reset the entire system:
1. On the BASE - Unplug from wall both power and phone line. Unplug battery from base handset.
2. ON the Extension phone - unplug from wall and unplug battery from handset.
3. Wait AT LEAST 5 minutes.
4. Plug back in BASE power.
5. Plug back in BASE phone line.
6. Plug back in EXTENSION handset battery. Don't plug in BASE handset yet.
7. Follow steps to program EXTENSION. When successful:
8. Plug back in BASE handset battery.

How do I add an extension handset to my current config?

IF it was a used handset it was likely registered to another base. I just switched bases (1line to a 2 line base). I had to "deregister" the handsets from the old base. I am not sure if you can deregister if the old base is not present? With the old base plugged into power I hit the "function key" at the bottom left of the handset and scrolled down to initial settings. Under registration is "deregistration". I selected that and it put the handset back to its default out of the box. Then simply hit the mute button on the New base and OK on the handset. Worked for all 5 of my old handsets.

Hope this helps

Verge cordless phone system v581tad

I believe you have the expansion capacity of the phone all used up. The phone cannot register any more handsets until you delete the handset registered that is not in use. First check the handsets and see what handset numbers they carry. It should be #1,#2,#3,and #4 if it does not then you will have to delete the one that is missing or if it is then delete handset #5.To do this you will have to use one of the handsets registered to the base. First Press the MENU/ OK button then scroll down to ADV,SETTING then Press MENU/OK then scroll down to DEREGISTER then Press MENU/OK. Then ENTER HANDSET PIN would show, if you have not changed the pin enter 0000 if you have enter your pin member. From the next options select HANDSET and press MENU/OK from the next set of options select the handset number you want to DEREGISTER and press MENU/OK from the next option select YES then MENU/OK. Then try to reregister the new handset To do this Press the MENU/OK button then go to ADVANCE SETTING press MENU.OK scroll to REGISTER then press MENU/OK Select the base number displayed then press MENU/OK. PLEASE WAIT will appear. Then from the base press and hold the PAGE button until the handset prompts you to ENTER PIN # .Enter 0000 OR your pin number then you will see PLEASE WAIT. A tone will confirm the handset registration.
