Align the brackets on the front edge of the window trim (inside mounting) or against the window (outside mounting).
INSTALL THE BRACKETS
Place each of the brackets against where you've drilled. Then, using the screws provided by the manufacturer and a drill, drive the screws through the bracket's holes.
INSTALL THE SHADES
Hold the shade with both hands and slightly tilt its top to the window as you hook the front edge behind the battery release tabs into the brackets.
