Your new scope is the finest example of Nikon's rugged and durable construction and precision bright optics; important qualities for a serious shooter's riflescope. Whether you use your scope for hunting or for target shooting, the procedure for mounting is identical. After mounting the scope on your riflescope, follow the procedures for reticle alignment. When setting the reticle for hunting, you should determine your standard range and then adjust the reticle based upon that reading distance. For targets which vary from that standard distance you may simply adjust the position of the reticle in relation to your target, or you may wish to use the procedure for trajectory compensation. It's up to your personal preference. We hope that you will enjoy your new Nikon Laser IRT for many years to come. Enjoy using it, and above all, always follow safe shooting procedures!

Diopter adjustment Look through the eyepiece with your eye positioned about 4 inches away from the eyepiece lens (Fig. 9), and you will see the Nikoplex reticle (Fig. 10), or the BDC reticle (Fig. 11). Be sure your eye is positioned within progper alinment and proper eye relief otherwise the view will "black out". Point the objective end of the scope at the sky (Do not point at the sun) or at a plain unpatterned wall. Turn the eyepiece adjustment counter-clockwise and then turn it clockwise until the reticle appears sharp. 2. Magnification The Laser IRT 4-12X42 has a variable magnification from 4 to 12X. To change powers. just rotate the power selector ring until the desired magnification appears adjacent to the power index dot (Fig. 2). 3. Adjustment of the riflescope Sighting through the riflescope, align the rifle with your aiming point on the target and shoot a trial round. If the bullet does not hit the aiming point, adjust the elevation and windage after removing the Adjustment cap, as follows: 4-12X42 For the Laser IRT adjustment is made by turning the grip by hand. If the bullet hits under the aiming point, turn the grip in the direction of the arrow marked "U". If the bullet hits to the left of the aiming point, turn the grip in the direction of the arrow marked "R" (Fig. 12). Note: The windage and elevation scales of the Laser IRT 4-12X42 is calibrated in divisions of 1/4 minute of angle with a click at intervals of 1/4 minute of angle (half division). When adjusting the reticle to the point of aim, remember that one minute of angle equals approximately one inch (2.54 cm) at 100 yards (91.44 m). Therefore, if the impact point is two inches (5.08 cm) low and one inch (2.54 cm) right at 100 yards (91.44 m) Parallax Setting, you should adjust two minutes of angle up one minute of angle left.
