WARNING..

Activating HAND mode when the CNVD-T3 is
being used in-line with a magnif ied day optic may
induce an error in the aiming function of the sight.

When being used in-line with an optical sight, the CNVD-T3
should be placed in ZOOM 1X, the reticle should be turned
off, and zeroing procedures associated with the primary sight
should be used. Ensure that the CLIPON setting is selected
via the CNVD-T3 Main Menu as described in section

5.2cm

When being used as a stand-alone device, the example
below shows how to align the CNVD-T3 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-T3 / 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-T3
objective lens is 5.2cm. 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 5.2cm +

3.1cm = 8.3cm down from the center of the target.
