Can only dial 9 or 1, 2-8 keys not working

All of the handsets appear to have lost their
registration to the base and will need to
be first de-registered then re-registered.
It may be necessary to do this in three stages.
First be sure that all of the handset batteries
are fully charged.
1.
Clear one of the handsets of its registration:
hold down both the [END] and [#] keys
at the same time until the display shows the
SYSTEM RESET menu.
Since the handset is not recognized by its
base, select "Base Not Available".
Confirm the choice by selecting "Yes".
This handset will now display
"Handset Not Registered"
--
2.
With "...Not Registered" displayed, place
the handset into the base unit cradle.
The handset should now dieplay
"Handset Registering"
After ~30 seconds the display should show
"Registration Complete" and will have a
handset unit number.
If the unit shows "Handset 1" (doubtful)
then just repeat steps 1 & 2 above for each
additional handset in turn. This can also be
the route if you do not care what the numbers
are and do not exceed the maximum count
for your system ( some are 4, 5, or even 12 ).
If the handset is a number other than 1 you
may want to clear the base & re-register
all of the handsets:
3.
Using the now-registered and working handset
(number x), press both the [END] and [#] keys at the same time until the display shows the
SYSTEM RESET menu.
This time, choose "Deregister HS" and the
System Reset Menu will prompt you to
select from the list of registered handsets
which one you want to deregister: choose
one that is NOT the one you have working.
Cycle around deleting them all until only the
one that is working is left: select that one and
the system will be ready to start re-registering
all handsets again from Handset #1.
Start at process (1) above, then (2).
Good Luck!!
===============================

335 is the magic code when you want to remove a previous handset or base station registration!
Handset:

1 " (middle soft key) i L i #

2 Enter "335".

3 "Cancel Handset" i #

LThe numbers of all handsets

registered to the base unit are

displayed.

4 Select the handset(s) you want to

cancel, by pressing the desired handset

number. i #
5 "Yes" i # i {ih}
Base Station:

A handset can be registered to a maximum

of 4 base units. A handset can cancel a base

unit that it is registered to. This allows the

handset to "forget" the base unit.

1 " (middle soft key) i N i #

2 "Registration" i #

3 Enter "335".

4 "Cancel Base" i #

5 Select the base unit(s) you want to

cancel, by pressing the desired base unit

number. i #
6 "Yes" i # i {ih}

Jill,
The only logical way is to get the additional handsets to communicate with the base. And to do that you must set them to the frequency of the base. You Use guide will tell you how to set the frequency n the handsets to talk to the base. They way you set the original ones.
BUT, I doubt if this will work. Why? Because if that was the case if you and I had the same company phones, then I would stand outside your home and set the same frequency on my handset and misuse your phone. A great security risk in today's world. But there is no harm trying it out. Just set the same frequency on the additional ones as the base. If it works, then you will have that many more intercoms too. And do let me know if it works.

Remove then replace the batteries from the hand set. You should now get dial tojo.

This works on MY panasonic; May work on yours too!

(Just received this from Panasonic Support...Thanks Panasonic!) The following might be worth a try.... Resetting Handsets & Base Unit: 1) Unplug AC adaptor from base unit for 30 seconds. 2) Reset handsets by removing/reinstalling all batteries.
Re-register each handset to the base unit by following the steps below:

1. Press MENU, #, 1, 3, 0 on the handset. 2. On the base unit, press and hold the LOCATOR button for 4 seconds until the registration tone sounds. 3. On the handset, press the soft key below OK and then wait until a long beep sounds. 4. Press the OFF button to exit. Situate the base unit in a different location. Change the line mode from A to B or vice-versa by following the steps below:

1. Press MENU on the handset. 2. Press #, 1, 2, 2. 3. Press the up or down arrow key to select the desired setting. 4. Press the soft key below SAVE. 5. Press the OFF button to exit. If the problems persist, your unit is malfunctioning and is in need of repair or replacement.

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.

2/29 Have you registered or re-registered the handset?
"No link" can mean handset is not accepting radio wave of base unit. At Mfgr website pull-down operator's manual and look for registration instructions. Some sequence of buttons will create a radio signal from base (have handset off base) then another sequence of buttons on handset will accept radio signal. If handset has "menu" button, try "menu", then "00" (zero zero) then select an accept or "OK" button. Good luck.
