Features
Setter
The setter changes the flashing rate. Turn CW to
increase the rate, turn CCW to decrease rate.
x2 Switch
Pressing "x2" will double and display the flashing rate.
1/2 Switch
Pressing the "1/2" will divide flashing rate by two and
display it.
Plus (+) Switch
When object appears to be standing still, pressing "+"
will give the illusion that the object is moving towards
the opposite direction of rotation. This action increases
the rate slightly (phase shift) and is used to place the
object in desired position.
Minus (–) Switch
When object appears to be standing still, pressing "–"
will give the illusion that the object is moving towards
the rotating direction. This action decreases the rate
slightly (phase shif) and is used for the same reason as
