If the wide angle (270°) coverage is too wide for your application, you may need to install the lens shield to reduce the coverage angle.
❒Decide which side of the lens you want to cover.
❒Curve the shield as shown. Slide the shield down, under the two metal ribs of the case. Make sure the shield slides all the way down so the entire shield will lay directly against the lens.
❒Slip the small protrusion behind the vertical metal rib to hold the top of the shield in place.

If the sensor is not kept level you may experi- ence an apparent decrease in range because objects may pass under the detection zone with- out being detected.
