Clicking the EVAC button initiates the evacuation of the specimen chamber. Similarly, clicking
the AIR button causes the AIR processing of the specimen chamber.
The display window to the left of the EVAC button lights up when the specimen chamber is in the
EVAC state; it blinks when the EVAC process is in progress; and in other cases it remains off.
Similarly, the display window to the left of the AIR button lights up when the specimen chamber
is in the AIR state; it blinks when the AIR processing is in progress; and it remains off in all other
cases.
