1b. Standard
This observation mode is suitable for observing either conductive or non-conductive
samples. Select this mode especially when observing non-conductive samples (e.g.
plastic, paper, fiber, rubber, ceramic, biological samples, foods, etc).
When [Standard] is selected, the [M] mark is displayed in the information area located
in the lower right part of the image observation area. (see 4.3.2)

1c. 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 such cases, 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)

2. SE (Secondary Electron)
Topographical information on a sample surface can be obtained. Every time the [SE]
button is clicked, [Standard] or [Chg-up Red.] is selected in order. The current mode will
be displayed under the [SE] button. Select a desired mode, depending on the specimen
to be observed and the observation purpose.
When [SE] is selected, the [U] mark is displayed in the information area located in the
lower right part of the image observation area. (see 4.3.2)
