: Pressing key one time decreases 1 resolution of “VI”.
ENT : Store “VI” value in the memory and completes the
(ii) Indicates present “VI” value.
(iii) Indicates “VI” value changed by pressing plus (+) or minus (-) key.
(iv) Response index number : The lower number denotes better response.
(v) Positioning index number : The rower number denotes quicker positioning.
Note: Changing “VI” step (3).
If you want to change the resolution of step, press space key or back space key.
Space key : Changes the step to 1/10 of present resolution.
(Pressing twice makes 1/100.)
Back space key : Changes the step to 10 times of present resolution.
