Figure 10 Zero Calibration
Figure 11 Reset Preset Menu
Reset preset is the correction between a
known target and the zero position when
target information and the zero drift are
known.
Reset preset information is a supplemen-
tary correction for the zero position based
on environmental conditions such as wind
speeds, air pressure, and target elevation.
The Reset preset menu includes four
options: Position correction, Height correction,
Save and quit, and Quit. The values in
reticle position under Zero Calibration and
those in Reset preset determine the
ultimate coordinates of the reticle. The
total adjustment value of the zero position
and the preset menu is within ±20mil, as
shown in Figure 11.

Descriptions of Zero Calibration
Position correction: You can move the
reticle leftward or rightward on the
screen by adjusting the position correction
parameters. Turn the encoder clockwise
to increase the values and move the
reticle rightward, or anticlockwise to
decrease the values and move the reticle
leftward.
Height correction: You can move the
reticle upward or downward on the
screen by adjusting the height correction
parameters. Turn the encoder clockwise
to increase the values and move the
reticle downward, or anticlockwise to
decrease the values and move the reticle
upward.
For the 25mm lens, the reticle moves
0.3142 mil each time; for the 35mm lens,
the reticle moves 0.22038 mil each time.
The change value of the azimuth is within
±20mil; please return to 1× display for
the reticle adjustment.
Save and exit: to save the current correction
values and exit to the first-level menu.
Exit: to exist to the first-level menu
