Pressing the left or right arrow will reduce or increase the Span and pressing the up
or down arrow will reduce or increase the Level. If the unit is in Automatic mode,
modifying any of these parameters will select Manual mode.
b）The second function performed is to force an internal calibration cycle. This is
performed by pressing and holding the A key for 5 seconds or more. The camera will
make automatic correction to get the most accurate thermal measurement.
[3] Cancel/Camera key (Marked “C”)
