Yukon Nvmt Spartan 24121 User manual

OVERVIEW
NVMT SPARTAN is a new line of night vision monoculars that includes three models - 2x24, 3x42
and 4x50.
NVMT SPARTAN is designed for observation in twilight or complete darkness. This is a passive type
device, i.e. it does not require artificial light, however the new high power IR Illuminator enhances
significantly the picture quality.
The device can also accommodate an accessory IR Flashlight (#29074).
NVMT SPARTAN is equipped with two ¼ inch tripod mounts that allow fixing the monocular onto a
head mount and use as goggles. This device features excellent ergonomics, compact dimensions and
handy controls.
The entire unit is rugged enough for extreme field conditions but damage may occur if the scope is
mishandled.
The NVMT SPARTAN is entirely self-contained and can operate for up to 20 hours on a single
CR123A battery at temperatures ranging from -20°C to +40°C (-4°F to +104°F).
Your NVMT SPARTAN scope is ideal for a variety of professional and recreational uses including the
following:

· Observation in natural environment
· Tourism
· Sporting events
· Search and rescue
· Equipment maintenance and repair
Your NVMT SPARTAN night vision scope was designed to provide many years of reliable service. To
ensure that you
get the most enjoyment out of your NVMT SPARTAN always obey the following Warnings and
Precautions:
· Do not direct a unit in the “on” position at intense sources of light, such as car's headlights or
burning fire. This may disable the unit for an unknown length of time or cause a dark spot in
the center of the field of view. Do not turn the unit on in daylight without the protective cap
firmly secured over the objective lens, as this may damage the unit. Any such damage may void
your warranty.
· Never leave the unit in the “on” position over an extended length of time in an area with a light
level exceeding 1-10 lux (twilight - 10 lux, deep twilight - 1 lux). Please keep the protective cap
on the objective under greater light level.
· Your NVMT SPARTAN was designed to be self-contained. Do not open the body of the scope
or otherwise attempt to service this device. If such need arises return the unit for replacement
or repair.
· Keep the NVMT SPARTAN away from dust, moisture and sudden temperature drop.
· Do not subject the unit to water drops and splashes, do not put water reservoirs on the device.
· Avoid dropping or otherwise shocking the unit. NVMT SPARTAN incorporates a sophisticated
optical system which could be damaged in extreme cases of misuse.
Damage to this device from failure to observe these warnings may void the NVMT SPARTAN's warranty!
BATTERY INSTALLATION
Your NVMT SPARTAN runs on a single CR123A battery. To install, unscrew the battery compartment
cover, insert the battery into the battery compartment observing the marking on the cover of the
battery compartment, replace the battery cover carefully. Do not overtighten.
USE AND TESTING
Make sure the battery has been installed according to instructions found in the battery installation
section of this manual.
· If you wish to test your night vision device in a lighted area, be sure the lens cap is in place
prior to pressing the “ON” button. The lens cap has a pinhole opening to admit a small
amount of light for testing purposes.
· Move into a dark area before activating the NVMT SPARTAN light amplifier.
· Remove the lens cap (1) and fasten it to the body as shown in the picture.
· Activate the device by pushing the "ON" button (3).
· Direct the turned on unit at an object at a distance of around 30m. Rotating the eyepiece (4),
focus on the tube's screen — rough surface or tiny dark dots are visible. Rotate the objective
lens (5) until the image quality is optimal. Re-focus the eyepiece, if necessary. After this
adjustment you may not rotate the eyepiece irrespective of the distance and objective lens.
· Direct your NVMT Spartan at an object to be viewed and adjust the final focus by rotating the

objective lens focusing ring until the image is optimal. When screwing the objective lens into
the housing, it focuses on farther objects, when screwing out - on closer ones.
· When you are finished using your NVMT Spartan put the cap back on the objective lens, turn
off the unit and put it into the carrying case. Push of the “ON” button when the IR is on will
make both green and red LEDs go out (IR will be off as well).
CAUTION!
Your NVMT SPARTAN can be used in extreme cold. However, when the unit is brought back into a
warm environment, you MUST wait approximately 2-3 HOURS before using the unit again. Failure to
do so may result in damage as a result of condensation accumulating on the internal circuitry of the
unit.
MAINTENANCE
· Clean the lens with professional lens cleaning supplies intended for use with multicoated optics.
· Blow any dust or dirt off the lenses using dry, compressed air.
· Clean the NVMT SPARTAN housing with a soft, clean cloth coated in some synthetic cleaning
means.
STORAGE
· Always store the NVMT SPARTAN in its case in a dry well-ventilated and well-heated room
away from heating/air conditioning vents. Remove the battery if the device is to be stored
longer than 2 months.
TROUBLESHOOTING
· The scope will not turn on...Check that the battery is installed properly. Install the battery
according to the (+) and (-) polarity, ensuring that the markings on the battery and battery
compartment correspond with one another. Check the battery contact to ensure it is clean and
free of corrosion; if necessary, clean the contact. Make sure that the external contact lug is not
bent. If necessary, replace the battery as it may be depleted. Also, be sure that the power is in
the “ON” position when trying to turn on the scope.
· Distinct black dots appear on the screen...
These dots are minor cosmetic blemishes resulting from tube production processes and do not
interfere with the reliability or performance of the scope.

· The scope flickers, flashes or “snows”...
The scope may flicker or flash when used in a bright environment; to correct this, place the
cap over the objective lens and enter a dark environment. The scope will restore itself to a
natural functioning state in several minutes or hours, depending on how long the scope had
been exposed to the light. The scope may flicker for the first several seconds of use, even
when in a dark environment, before the scope corrects itself and functions properly. The
scope may “snow” for several minutes after being exposed to a bright light source (daylight,
a car's headlights, fire, etc.) even if being operated in complete darkness.
· The image is not focused...
Adjust the focus of the eyepiece and the objective (see Use and Testing). Check that the
lenses are not foggy or dusty; if they are, carefully clean the external surfaces of lenses with
a soft cotton fabric. Replace the battery if the total battery charge is less than 2.0 V. When the
unit is brought into a warm environment from a cold one, condensation may appear on the
internal lenses;you must wait two hours before using the unit.
· Visibility decreases or disappears...
Bright light sources, such as headlights, may cause visibility to decrease or disappear and the
image to flicker. Turn the power off and turn the scope away from the light source; visibility
will restore itself in several minutes.
