• 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

to accept the new code and complete re-registration.

• Unplug the old base unit. Your handset will display "SEARCHING...".
• Install the new base unit by plugging it into an electrical outlet and phone jack.
• 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. The handset is
now registered to the new base.
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.
