How do I lock the dispenser to prevent unintentional use by children?

Press and hold the LOCK button for 3 seconds to lock the dispenser. Press and hold LOCK a second time to unlock the dispenser, and the display screen will indicate when the dispenser is locked. Note that the lock feature does not shut off power to the refrigerator, the ice maker, or the dispenser light — it simply deactivates the controls and dispenser paddles. (Page 24)
