Usage Tips: [Soft Green Lighted Wall Button] – The housing is made of black plastic with a white center strip. It operates with a single tap to turn on/off and emits a soft green light. The contrast between the white center and green illumination makes it easy to locate in low-light conditions, providing convenient garage door operation. [Compatibility] – This wall-mounted garage door opener button is compatible with LiftMaster 75LM remote controls and serves as a replacement for standard garage door opener wall switches. [Easy Installation] – Disconnect the two wires from your existing garage door opener. Connect these wires to the terminals on the internal circuit board of the button. Mount the unit securely to the wall using the included screws. Once installed, pressing the button will illuminate the soft green LED. Note: Wires are not included with the push button.
