·After making sure it is charged set the telephone on the main base again press and hold the Find button for 4 seconds ( until the red light IN USE comes on) Then release the find button. The headset will show PLEASE WAIT; this takes about 10 seconds to complete the registration. The hand set will show HEADSET REGISTERED and the headset number assigned, you will hear a beep when the registration is finished
·When the registration is complete, the newly registered handset is assigned the next available handset registration number. For instance, if you already have HANDSET 1 and HANDSET 2, the next registered handset is HANDSET 3.

The phones need to be unregistered and then re-registered, which you can find in the troubleshooting section of your User Mannual or go to theis webpage http://www.scribd.com/doc/4088938/Vtech-i6789-phone-manual-i6789-manual-i3

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.
