3b. Chg-up Red.
When observing non-conductive samples in the [Standard] mode, brightness /
contrast can change over time (i.e. brightness change) or image can look shifted
unexpectedly (i.e. image deviation). In this case, set the observation mode to [Chg-up
Red.].
When [Chg-up Red.] is selected, the [L] mark is displayed in the information area
located in the lower right part of the image observation area. (see 4.3.2)
