You can re-register handsets after de-registering from the base.

Or you can re-register handsets to a new base unit, if you have replaced your base unit for any reason.

•Make sure your handset batteries are properly installed and charged.

•Your handset will display “SEARCHING...”

•Press and hold the SELECT key until the handset displays “ENTER BASE ID”.

•Enter the 15 digit Base ID number from the bottom of the base unit.

•Press SELECT to accept the new code and complete re-registration.

To re-register a handset to a new base unit:

•Make sure your handset batteries are properly installed and charged.

•Unplug the old base unit.

•Install the new base unit by plugging it into the electrical outlet and phone jack

•Your handset will display “SEARCHING...”

•Press and hold the SELECT key until the handset displays “ENTER BASE ID”.

•Enter the new15-digit Base ID number from the bottom of the new base unit.

•Press SELECT to accept the new code and complete re-registration.

NOTE: If an invalid base ID code is entered you will hear an error tone and the handset will continue to display “ENTER BASE ID”. To make corrections while entering the code, you can erase digits by pressing the DELETE key.

Once a valid base ID code is entered and accepted by the base unit, the new handset will be assigned the next available handset number. You can register a maximum of four handsets per base unit.
