Unobstructed Line of Sight

For optimum readability, install the Encompass 4 Reader and the vehicle's tag so that
when the vehicle approaches the Encompass 4 Reader, the tag is directly facing the
reader and the line of sight is clear between the Encompass 4 Reader and the tag. If a
fence or barrier is between the tag and the reader, the Encompass 4 Reader cannot reli-
ably read the tags. Figure 2-2 illustrates possible installation locations of an Encom-
pass 4 Reader in relation to a tag's mounting location on a vehicle. If the tags are not
in the recommended location, reliable optimum operation requires lower vehicle
speeds.
