FM 3-22.11. Verify that the TAS reticle aligns with the zero target.2. Check that backup sight reticle's center vertical line aligns with the target. (Tomove reticle in azimuth, loosen horizontal adjustment lockscrew and turnhorizontal adjustment screw. Use screwdriver)3. Align reticle so that the AP range line aligns with the target at theappropriate range. (To move reticle in elevation, loosen locknut on elevation leverand adjust thumbscrews. Use wrench and socket.)4. Verify that the TAS reticle and the AUX reticle range line are both on target.5. Have commander observe round impact point.6. Fire one confirmation tracer round at the zero target.7. If round does not hit the target, verify TAS reticle is center mass of zero target.Figure C-2. Steps for zeroing the auxiliary sight to the 25-mm gun.c. Zero Auxiliary Sight to Coax. To zero the coax, use the checklist shown inFigure C-3.Press CONTINUE.1. Ideally, use the DVO. If you use the TV FLIR, do so only at night.2. Select HI MAG (NFOV) using the HI/LO switch on the GHS.3. Using the T&E handwheels, center the AUX sight on the target. Use the HE rangeline (the outer, broken range lines) for the range displayed in the DVO (800-metertarget).4. Range the target using the laser range finder, or manually index it on the GSCP.5. Using the T&E handwheels, center the AUX sight on the target using the HE rangelines for the range displayed in the DVO (800 meters) .Make the following adjustments with the coax knobs, not with the AUX sight:6. Have the commander observe the round impact.7. Fire one burst of 10 to 15 rounds at the target.8. Open the coax access doors. Manually move the coax azimuth and elevationknobs. This will move the strike of the rounds to center mass of the coaxzero target.9. Repeat Steps 5 through 8 until you zero the coax. If you cannot zero the coaxin three bursts, notify the unit master gunner.Figure C-3. Steps for zeroing auxiliary sight to the coax.C-3
