6.4.5 Position the Anchors
6.4.5.1 By using the Auto-Positioning Feature (for up to 4 anchors)
Note 1:
The Auto-Positioning function is a quick setup feature to automatically
determine the anchor locations. Note that this feature may result in a small error in
anchor location, making reported tag locations less accurate. For best results it is
recommended that anchor positions are measured to cm accuracy and manually
entered (see below)
Note 2:
Ensure Line-of-Sight between the anchors during these steps
