The PROSTAFF 5 Riflescope 3.5-14×50 SF IL and 4.5-18×40 SF IL are powered by one 3V lithium battery (CR2032). When your reticle

grows dim or not light at all, you need to replace the battery.

w t

plac

att

Hold the rheostat intensity dial tightly and turn the cover with battery cover opener

counter-clockwise (Fig. 3-1).

Take out the old battery and put one 3V Lithium Battery

into the compartment. Be sure (+) side to be up (Fig. 3-2).

Put the cover back and turn it clockwise with battery cover opener until the cover in firmly secured.

Turn the rheostat intensity dial to the desired color (red or green) and intensity (6 steps: OFF to 5) (Fig. 3-3).

*The Nikon PROSTAFF 5 Riflescope comes with a 3V lithium battery (CR2032).

*Replace the battery if the Nikon PROSTAFF 5 Riflescope is ever submerged in water or if water enters the battery chamber.

Look through the eyepiece with your eye positioned about 10 cm (4 in) away from the eyepiece to see the BDC reticle (Fig. 3-4),

the Duplex reticle (Fig. 3-5), the Fine Crosshair w/Dot reticle (Fig. 3-6), or the Mildot reticle (MILstandard) (Fig. 3-7). Be sure

your eye is positioned with proper alignment and with proper eye relief, otherwise the view will “black out.”

Point the objective end of the scope at the sky (NOT point it 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.

The PROSTAFF 5 Riflescope has variable magnification. For details, see “2. Specifications”.

To change powers, rotate the power selector ring until the desired magnification appears adjacent to the power index dot.

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 as follows:

•

If the bullet hits under the aiming point, turn the elevation adjustment turret (counter-clockwise) in the direction of the arrow marked “U” for up. If the bullet hits high, turn the elevation adjustment turret (clock-

wise) in the direction of the arrow marked “D” for down.

•

If the bullet hits to the right of the aiming point, turn the windage adjustment turret (clockwise) in the direction of the arrow marked “L” for left. If the bullet hits to the left of the aiming point, turn the windage

adjustment turret (counter-clockwise) in the direction of the arrow marked “R” for right.

•

For the high profile turret, adjustment is made by turning the turret by hand. If the bullet hits under the aiming point, turn the turret in the direction of the arrow marked “U”. If the bullet hits to the left of the

aiming point, turn the turret in the direction of the arrow marked “R”.

•

After the reticle has been adjusted to the point of impact, replace the turret cap for both the windage and elevation adjustment turrets.

t t

urre

The elevation adjustment and windage adjustment turrets have a retracting system. After the reticle has been adjusted to the point of impact, pull out the

elevation adjustment or windage adjustment turret.

The turret can now be turned freely. Align the zero number to the index line to set the zero setting, and then release the turret. The turret automatically

retracts to the original position.

(6)

g th

urre

Remove the turret cap by turning it counter-clockwise. Align the turret to the 0 (zero) position of the scale ring. This is to assure that the scale ring will be

correctly aligned to the new turret. (The alignment position should be remembered.)

With the turret held with your fingers to avoid shifting of the aligned scale ring, turn the screw in the top of the turret counter-clockwise with the supplied

hex key

until the screw comes out. Then remove the turret (Fig. 3-5).

Insert the new turret into position and align the scale ring to 0.

Insert the screw. By securing the turret with your fingers to avoid shifting of the scale ring, turn the screw clockwise with the supplied hex key, until the turret

is firmly secured.

*Please refer to “Supplied Item(s)” to see if your riflescope is provided with high profile turrets.

The PROSTAFF 5 Riflescope 3.5-14×40 SF, 3.5-14×50 SF, 4.5-18×40 SF, 3.5-14×50 SF IL and 4.5-18×40 SF IL can be more

precisely focused within the range of at least 45.72 m (50 yd) to infinity by rotating the side focus adjustment

(Fig. 3-9 or 3-10).

Parallax can be eliminated and sight alignment will be accurate.

Use its distance scale as a reference guide.

The windage and elevation scales of the PROSTAFF 5 Riflescope 2.5-10×40, 2.5-10×50, 3.5-14×40 SF, 3.5-14×50 SF and 3.5-14×50 SF IL are calibrated in divisions of 1/4 minute of angle with a click at intervals

of 1/4 minute of angle (1 division).

•

The windage and elevation scales of the PROSTAFF 5 Riflescope 4.5-18×40 SF and 4.5-18×40 SF IL are calibrated in divisions of 1/8 minute of angle with a click at intervals of 1/8 minute of angle (1 division).

•

When adjusting the reticle to the point of aim, remember that 1 minute of angle equals approximately 2.54 cm (1 in) at 91.44 m (100 yd).

Therefore, if the impact point is 5.08 cm (2 in) low and 2.54 cm (1 in) right at 91.44 m (100 yd) Parallax Setting, you should adjust 2 minutes of angle up and 1 minute of angle left.

In the case of 45.72 m (50 yd) Parallax Setting, the adjusting value is 2×. In the case of 68.58 m (75 yd) Parallax Setting, the adjusting value is 1.5×.
