Note Changes made to the Clarity tab are handled according to the way the
Interactive Properties dialog box was launched. If the dialog box opened as
the result of an exception, the changes apply to the image in question only. If
the dialog box opened because you selected Preview or First Page mode, the
changes also apply to subsequent scans. When VRS restarts, the tab is reset to
the settings in the last selected profile. Böwe Bell + Howell Spectrum series
scanner users should refer to the note on page 37.
