Press function button on handset, scroll to initial setting, select by pressing right arrow, scroll to registration, select, select hs registration, follow directions on handset display, pressing mute on "new" base station, and ok on handset(plugged in). If you like, you can unregister with the "old" base unit first.

No Link to Base - - Walk closer to base and try again --

You should try resetting both the base and handset but removing their power supply/batteries and then reconnecting their power supply/batteries. You can also check and see if there is a registration option on the handset that will re-link it with the base. Could just be broken though!

My phone display's No link to base. Reconnect main bas AC adapter. It is plugged in what now?

I had this problem, and I fixed it by re-registering the phone to the base. Here are the directions for how to do that from the manual:


Registering a handset to the
base unit
The supplied handset and base unit are
pre-registered. If for some reason the
handset is not registered to the base
unit, re-register the handset.
1 Handset:
2 {V}/{^}: "Initial setting"
3 {V}/{^}: "Registration"
4 {V}/{^}: "HS registration"
5 Base unit:
- KX-TG4011 series:
Press and hold {LOCATOR} for
about 5 seconds. (No registration
- KX-TG4021/KX-TG4071 series:
Press and hold {LOCATOR} for

about 5 seconds until the
registration tone sounds.
If all registered handsets start
ringing, press the same button to
stop. Then repeat this step.
The next step must be completed
within 90 seconds.
6 Handset:
Press {OK}, then wait until a long
beep sounds.
While registering, "Base in
registering mode" is displayed on
all registered handsets.
When you purchase an additional
handset, refer to the additional
handset's installation manual for

Kx-tg1100 registration to anoter base

sorry, it seems that they have to come from the same model base. however, the procedure to reset handset numbers for the 1100 may work for you. there is a 15 digit number on the base unit. try to type that into the 1100 and see if that will register the 1100 to your old base.

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.

Panasonic kx-tg1100

On the handset you want to discard go to "SETTINGS HS" -> "REGISTRATION" -> "CANCEL BS"
This will discard the registration of the handset to any base.

Using the handset you want to register go to "SETTINGS HS" -> "REGISTRATION" -> "REGISTER HS"and select the base you want (i.e. BASE 1, BASE 2, ..., BASE n).

NOTE:If you do not get access to the BASE you are looking for (STEP 2) then you have to cancel the registration of the new handset to any base. Therefore, follow STEP1 for this handset as well and then follow STEP 2.

After you finish all the above, hold down the "PAGE" button for about 5 secs.

You are now done!!!

Good luck
