INSTRUCTION MANUAL
E
Congratulations on your choice of a Nikon Laser IRT. Your new
scope is the finest example of Nikon's rugged and durable construc-
tion 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 stan-
dard range and then adjust the reticle based upon that reading dis-
tance. 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.
Please observe the following guidelines strictly so you can use the
equipment properly and avoid potentially hazardous problems.
Before using this product, read thoroughly the "SAFETY PRECAU-
TIONS" and instructions on correct usage accompanying the prod-
uct. Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.

The Nikon Laser IRT emits invisible, eyesafe, infrared energy pulses
that reflect off the selected target back to its optical receiver.
Sophisticated precision charge circuitry is used to instantaneously
calculate distances, by measuring the time it takes for each pulse to
travel from the rangefinder to the target and back. The maximum
range of the instrument depends on the reflectivity of the target, its
color, surface finish, size and shape.

This indication alerts you to the fact that any improper use ignor-
ing the contents described herein can result in potential injury or
material loss.
蘆When removing stains or smudges like fingerprints from the
lens surface, wipe the lenses very gently with a soft clean cot-
ton cloth or quality oil-free lens tissue.
Use a small quantity of pure alcohol (not denatured) to wipe
stubborn smudges. Do not use velvet cloth or ordinary tissue,
as it may scratch the lens surface. Once the cloth has been
used for cleaning the body, it should not be used again for the
lens surface.
SAFETY AND OPERATION PRECAUTIONS
Warning
蘆Never look directly at the laser beam or directly at the sun

when using the Nikon Laser IRT.
蘆Do not depress the POWER button while aiming with the eye
or looking into the optics from the objective side.
蘆Do not operate the unit with other additional optical elements,
such as lenses or binoculars. Using an optical instrument
together with the Nikon Laser IRT increases the danger of
damaging the eyes.
蘆Do not disassemble the Nikon Laser IRT. A product that has
been disassembled is not guaranteed by the manufacturer.
