This procedure sets the threshold as the average of the received light
levels at the two positions for which teaching was performed. For
example, the received light for the first point is 4000 and the received
light for the second point is 2000. The threshold is automatically set to
3000.
Figure 9 - Position/Precision Teach
This procedure sets the threshold for the received light levels at the
position to be detected. For example, the received light level during
position teach is 1000 and the threshold is automatically set to 1000.
