[Start] means that electron beam irradiation is off (HV-OFF). Clicking the [Start] button turns
on the power source for the electron gun in order to irradiate the specimen with the electron
beam, and the process of heating by the filament commences, a process that requires
approximately 10 seconds. As a window indicating processing in progress appears, begin
observation operations after the window has disappeared. During the observation, the button
remains lit, and the display changes to [Stop]. During this operation, change the View mode
to an FOV search mode.

After launching the application or changing specimens, operate the Start button by executing
Auto Start (after filament heating, run auto focusing and Auto B/C adjustment). In this case,
set the observation magnification to 100x.
