Try this, Push and hold the "End" key, while still pushing the "End" key push in the "#" key and hold both keys till you hear a beep. The LCD display should now say "De-register Handset" and under that "Base Unavailable" Select Base unavailable. The LCD should now say "Handset not registered, place in base" Just set it in the charging cradle on the base unit and it should register to the base.

When trying to make a call,messages appears unavailable on both hand sets that i have,i can not receive or send calls, but my land line does.

I put the phone on the master handset (I registered it)

Same manual as lethean provided on a similar post but Page 24 if the previously used Base is Unavailable and your phone shows "Deregistration" in the Menu.

Base Unavailable (Handset Only)
To clear the base registration data in the handset, please follow these steps:
Press and hold [] and [#] for more than 5 seconds. Select the BASE UNAVAILABLE submenu.
BASE UNAVAILABLE appears. Move the cursor to select YES, and then press the OK soft key.
ARE YOU SURE? appears. Move the cursor to select YES. Press the OK soft key.

You have to register the hand set in the main base. Place each handset in the base for 15 seconds minimum. It will change form unavailable to Ready when it grabs the signal from the base. If the power goes out, you will have to re-register each hand set in the base before you use them again.

Have you followed the instructions for handset registration? For some of the newer handsets, you may need to refer to the instructions that came with the handset (and not the base) instead of just putting the additional handset in the base to register it.

Page 23 of the 9480 manual gives explicit registration instructions.

I charged my three brand new GE model 25922 for 24 hours, placed each handset in the main base to satisfy the "PLEASE REGISTER" message and the message remains. The only instruction in the manual as well as on the 800 448-0329 # is to place each handset in the base unit for 20 seconds.
