Setter: Changes the flashing rate
11.
(x2) Switch: In the internal mode, pressing “x2”doubles the flashing rate
12. (+) Switch: In the internal mode, when object appears to be standing still,
pressing “+” will give the illusion that the object is moving towards the
rotating direction at a speed of 1 rotation in 6 seconds
13.
(÷2) Switch: In the internal mode, pressing “÷2” divides the flashing rate
by two
14.
(–) Switch: In the internal mode, when object appears to be standing still,
pressing “–“ will give the illusion that the object is moving in reverse at a
speed of 1 rotation in 6 seconds
