Rack mounting is optional. Adhesive rubber feet are included for non-rackmount installations. Use them to prevent the unit from scratching or marring support surfaces.Rack MountingRack mount the BASIS 722az by supporting it from underneath while aligning the mounting holes with the threaded screw holes in therails; install all four mounting screws and washers and tighten securely. Ensure use of all four mounting screws in order to minimize thechance of bending or distorting the rack mount ears.
