Abstract
Abstract A movable barrier or garage door operator has a control head controlling an electric motor connected to a movable barrier or garage door to open and close it. The control head has an RF receiver for receiving RF signals from a hand-held transmitter or a fixed keypad transmitter. The receiver operates the electric motor upon matching a received code with a stored code. The stored codes may be updated or loaded either by enabling the learn mode of the receiver from the fixed keypad transmitter or from a wired control unit positioned within the garage.
