ASSEMBLY  Remove the tape securing the Wi-Fi antenna and raise it to an upright position to ensure the best Wi-Fi signal. NOTE: Ensure that the antenna is screwed into the power head securely.  Place the sprocket onto the motor shaft with the round side of the sprocket facing up.  Hold the rail assembly above the power head with arrow pointing toward the front of the power head and the garage door.  Rotate the rail assembly until the opening in the rail is aligned with the sprocket.  Lower the end rail onto the sprocket with the channel (open end) facing down. Slowly rotate the rail to the correct orientation as you lower it into position.  When installed correctly, the teeth on the sprocket should engage the rail assembly and the rail should sit flat on the power head.  Place the brackets on top of the studs, and over the end rail.  Place nuts onto the studs and tighten using a 10 mm socket. Do not overtighten. Front of Power Head Nut Nut Stud Stud Sprocket Stud Wi-Fi Antenna Fig. 24 Bracket Stud Front of Power Head Wi-Fi Antenna Fig. 23 Fig. 25 19 - English
