To restrict the sensor coverage, preventing detection in unwanted areas, mask the sensor lens
using the masking label provided (see diagram D). The top section of the lens covers long
range detection, the bottom covers short range. Similarly the left and right lens sections
cover the left and right detection areas respectively.
