.
WARNING..
Activating ZOOM 2X when the CNVD-T is used in­line with other optical sights may induce an error in the aiming function of those devices.
When being used in-line with an optical sight, the CNVD-T should be placed in ZOOM 1X, the reticle should be turned off, and zeroing procedures associated with the primary sight should be used. Placing the CNVD-T in front of an already zeroed optic / weapon combination does not necessitate rezeroing.
2.15.2
Stand-Alone
. Each click of the CNVD-T reticle moves the shot group about 2.8cm at 25m (when in ZOOM 1X). Other click equivalents are provided in Table 2-1. Changing the position of the reticle corresponds to a subsequent change in shot group movement (i.e., the UP button will move the strike of the round up).
Table 2-1 Reticle Adjustments
Single Click Equivalents

5.9cm
When being used as a stand-alone device, the example below shows how to align the CNVD-T2 to be parallel with the rail of the host weapon on a 25-meter range. This “infinite parallel” configuration is appropriate for many mission profiles. Once parallel, the CNVD-T2 / weapon combination may be zeroed in accordance with established unit, departmental, or agency procedures.
a. Once mounted to a weapon, the distance from the
top of the rail to the centerline of the CNVD-T objective lens is 5.9cm. Calculate the designated strike point by adding this value to the distance from the center of the weapon barrel to the top of the weapon rail (3.1cm for an M4/M4A1). Therefore, in this example, the designated strike point is 5.9cm +
3.1cm = 9.0cm down from the center of the target.

2-23
b. Mark the designated strike point on a standard 25-
meter zeroing target.
c. Draw a designated strike zone around the strike
point that corresponds in size to an acceptable degree of desired accuracy.
Figure 2-19 Designated Strike Zone
d. Mount the target on an “E” silhouette or other
suitable surface at 25 meters.
e. Mount the CNVD-T to the weapon.
2-24
f. Turn on the CNVD-T using the startup procedures in
section 2.11.
g. Align the CNVD-T reticle with the center of the target
per paragraph 2.12.5.
h. Fire a 3-round shot group and note the center of the
shot group relative to the designated strike point.
i. Adjust the position of the reticle to move the center
of the shot group to the designated strike point.
j. Fire another 3-round shot group and again observe
the center of the new shot group relative to the designated strike point.
k. When 2 out of 3 rounds are in the designated strike
zone, the CNVD-T is aligned to be parallel with the rail of the host weapon.
