Tips for position adjustment

You can easily specify the reference position if you first input approximate coordinate values and then adjust them using arrow buttons in the "Reference coordinate" area. The Zoom function is useful for fine adjustment.
For the Zoom function, see User's Manual, "Using Zoom Function".
