Operational Summary
Riflescope
1. Diopter adjustment
盧
Look through the eyepiece with your eye positioned about 4 inches away from the eyepiece lens (Fig. 9), and you will see the Nikoplex reti-
cle (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".
盪
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
蘆
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
蘆
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:
蘆
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).
蘆
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.

***The battery chamber is water resistant, not waterproof. Water may enter the device if the laser IRT is submerged in water. If water enters the
battery chamber, wipe out any moisture and allow time for the chamber to dry.
●
Waterproof models:
The Laser IRT is waterproof, and will suffer no damage to the optical system if submerged or dropped in water to a maximum depth of 2 meters
for up to 5 minutes.
The Laser IRT offers following advantages:
蘆
Can be used in conditions of high humidity, dust and rain without risk of damage.
蘆
Nitrogen-filled design makes it resistant to condensation and mold.
Observe the following when using the Laser IRT:
蘆
As the unit does not have a perfectly sealed structure, it should not be operated nor held in running water.
蘆
Any moisture should be wiped off before adjusting movable parts (Power selector Ring, eyepiece, etc.) of the Laser IRT to prevent damage and
for safety reasons.
To keep your Laser IRT in excellent condition, Nikon Vision recommends regular servicing by an authorized dealer.
Troubleshooting/Repair
If your Nikon Laser IRT should require repair, please contact your local dealer for details regarding where to send it. Before doing so, you are
advised to consult the Troubleshooting Table below.
