2.8 CONTRAST (GAIN) ADJUSTMENT (Continued) If the LEFT / RIGHT buttons are not pressed within 3 seconds, the contrast scale will disappear and the CNVD-T2 will revert to normal viewing mode. Once adjusted, the contrast will remain at the applied setting (even if the CNVD-T2 is turned off) until readjusted by the operator. Auto-Gain Control The CNVD-T2 may also be placed in one of two auto-gain modes:
• AUTO-LOW mode is accessed by repeatedly pressing the RIGHT button to move the status bar along the contrast scale. As the status bar approaches the extreme right (+) end of the scale, the word MANUAL will be replaced by the word AUTO-LOW.
• While in AUTO-LOW mode, pressing the RIGHT button once more will place the CNVD-T2 in AUTO-HIGH mode. The word AUTO-LOW will be replaced by the word AUTO-HIGH.
Adjusting the contrast in MANUAL mode allows for lower and higher settings than either AUTO mode. 2.9 FOCUS ADJUSTMENT The objective lens must be focused for the viewing distance being observed. Rotate the objective focus ring for best image clarity. A change in viewing distance requires that the lens be refocused. However, if already focused for a distance of at least 75m, no change in focus is required between this distance and infinity.
2-12
2.10 IR LASER POINTER When the CNVD-T2 is turned on, pressing (and holding) the Laser Button activates the IR Laser Pointer until pressure is released from the button. Continuous activation is accomplished by double-tapping the Laser Button. While in continuous mode, pressing the Laser Button again (single-tapping) turns the laser off. When the Laser Pointer is activated, a laser reticle appears in the eyepiece display with the word “LASER” directly beneath. Further indication that the Laser Pointer is activated is provided by the green Laser LED shown in Figure 1-3. If previously displayed, the boresight reticle is replaced by the laser reticle when the IR Laser Pointer is activated. Once the laser is turned off, the boresight reticle will reappear in the eyepiece display. The laser reticle indicates the aim point of the IR Laser Pointer within the field of view. 2.11 STARTUP PROCEDURES For optimal performance and image clarity, the following procedures should be accomplished in the order presented, each time the CNVD-T2 is to be placed into operation: 1.

SECTION IV
ALIGNMENT / ZEROING
2.23 ALIGNMENT / ZEROING PROCEDURES Clip-On
WARNING
Activating ZOOM 2X when the CNVD-T2 is used in-line with other optical sights may introduce an error in the aiming function of those devices.
When being used in-line with an optical sight, the CNVD-T2 should be placed in ZOOM 1X, the boresight reticle should be turned off, and zeroing procedures associated with the primary sight should be used. Placing the CNVD-T2 in front of an already zeroed optic / weapon combination does not necessitate rezeroing. Stand-Alone Each click of the CNVD-T2 reticle moves the shot group about 0.7cm at 25m (when in ZOOM 1X). Other click equivalents are provided in Table 2-1. Changing the position of the boresight 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 10m 25m 100m 150m 300m
ZOOM 1X 0.3cm 0.7cm 2.6cm 3.9cm 7.9cm ZOOM 2X 0.1cm 0.4cm 1.3cm 2.0cm 3.9cm
2-23
2.23 ALIGNMENT / ZEROING PROCEDURES (Continued) 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. 1. Once mounted to a weapon, the distance from the top of
the rail to the centerline of the CNVD-T2 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.
Figure 2-12. Strike Point Calculation.
5.2cm
2-24
2.23 ALIGNMENT / ZEROING PROCEDURES (Continued) 2. Mark the designated strike point on a standard 25-meter
zeroing target. 3. Draw a designated strike zone around the strike point that
corresponds in size to an acceptable level of desired accuracy.
Figure 2-13. Designated Strike Zone.
2-25
2.23 ALIGNMENT / ZEROING PROCEDURES (Continued) 4. Mount the target on an “E” silhouette or other suitable
surface at 25 meters. 5. Mount the CNVD-T2 to the weapon. 6. Turn on the CNVD-T2 using the startup procedures in
section 2.11. 7. Turn the boresight reticle on via the system menu and
align the reticle with the center of the target per section section 2.18.
8. Fire a 3-round shot group and note the center of the shot group relative to the designated strike point.
9. Adjust the position of the reticle to move the center of the shot group to the designated strike point.
10. Fire another 3-round shot group and again observe the center of the new shot group relative to the designated strike point.
11. When 2 out of 3 rounds are in the designated strike zone, the CNVD-T2 is aligned with the rail of the host weapon.

3.3 CORRECTIVE MAINTENANCE The CNVD-T2 has no internal parts or assemblies replaceable by the user or organizational level personnel. Refer to section 3.4 regarding maintenance and/or repair actions beyond those described in this manual. Throw-Lever Tension Adjustment The throw-lever mounting bracket has a locknut that adjusts the tension required to clamp it to the weapon rail. It is preset at the factory but may need adjustment when initially mounted to the rail of the host weapon. If adjustment is required, the following procedures apply and are performed with the CNVD-T2 removed from the host weapon:
CAUTION Creating too much tension with the locknut may result in damage to the mounting bracket when the throw-lever is forced against the weapon rail. Creating too little tension with the locknut may allow for movement of the CNVD-T2 on the rail. Never completely remove the locknut from the mounting bracket.
1. Swing the throw-lever closed (against the body of the
CNVD-T2), then push in the lever lock to engage the locking mechanism.
2. Using the provided 3/8” box wrench, adjust the locknut using slight movements (2 or 3 degrees). Turning the locknut counterclockwise will decrease tension on the throw-lever. Turning it clockwise will increase tension on the throw-lever.
