To re-register a handset to a new telephone base

SELECT/MENU key until the handset displays
ENTER BASE ID.
• Enter the 15-digit base ID code located on the bottom of the
E5640, E5643B and E5644B telephone base. To find the number
on the E5655, go to the telephone base, press
SELECT/MENU
on the telephone base and scroll down to highlight DISPLAY
BASE ID, then press SELECT/MENU.
• After entering the code, press SELECT/MENU to accept the

NOTE: If an invalid base ID code is entered, you will hear an error tone and the

the code, erase digits by pressing the DELETE/MENU key.
Once a valid base ID code is entered and accepted by the
telephone base, the new handset will be assigned the next
available handset number (Handset 2, Handset 3, or Handset

telephone base.
