Explanation
The usable range of the D Beam controller
The diagram shows the usable range of
the D Beam controller. Waving your
hand outside this range will produce no
effect.
The usable range of the D Beam
controller will become extremely small when used under
strong direct sunlight. Please be aware of this when using
the D Beam controller outside.
The sensitivity of the D Beam controller will change depending
on the amount of light in the vicinity of the unit. If it does not
function as you expect, adjust the D Beam Sens parameter as
appropriate for the brightness of your location. Increase this
value will raise the sensitivity (p. 46).
