Yukon Advanced Optics 24021, 24027, 24022WP, 24021WP, 24057 User manual

OVERVIEW

Your NVMT starlight night vision scope is a professional specification night vision device designed
to provide enhanced viewing in all low light conditions including total darkness.
The NVMT is a passive starlight device; it does NOT require any artificial light source, although an
artificial infrared light will greatly enhance the scope's effectiveness in all facets of operation. NVMT
is constructed using an electro-optical intensifying tube contained in a water-resistant composite
housing. The entire unit is rugged enough for extreme field conditions but damage may occur if the
scope is mishandled.
The NVMT is entirely self-contained and can operate for up to 20 hours (40 hours for NVMT Gen.
2+) on CR123A battery at temperatures ranging from -22°F to +104°F (-30°C to +40°C).
Your NVMT scope is ideal for a variety of professional and recreational uses including the
following:

• Wild life observation

• Astronomy

• Boating

• Search and rescue

• And many other activities...

WARNINGS AND PRECAUTIONS

Your NVMT night vision scope was designed to provide many years of reliable service. To ensure
that you get the most enjoyment out of your NVMT always obey the following Warnings and
Precautions:

• Do not point the NVMT towards any light source greater than 1 lux (such as car headlights)

for an extended period of time. Our NVMT utilizes an internal flash protection system,
which minimizes potential damage, but long-term exposure to bright lights can damage the
unit. Any such damage may void your warranty.

• Your NVMT was designed to be self-contained. Do not open the body of the scope or

otherwise attempt to service this device.

• The replacement of eyepiece and objective lenses in the 24021WP and 24022WP models is

prohibited: this may cause depressurization of the device.

• Always store the NVMT in a dry, well-ventilated room. Keep the NVMT away from any

heating and air conditioning vents or other heating devices, direct sunlight, and moisture.

• Avoid dropping or otherwise shocking the unit. Although designed for rugged outdoor use,

the NVMT incorporates a sophisticated optical system which could be damaged in extreme
cases of misuse.

• Clean optical parts (lenses) with professional lens cleaning supplies designed for use with

multicoated optics.

• Clean the exterior of your NVMT with a soft, clean cloth.

Damage to this device from failure to observe these warnings may void the NVMT's warranty!

BATTERY INSTALLATION

Your NVMT runs on one battery - CR123A. To install, unscrew the battery compartment cover,
insert the battery into the battery compartment so that the positive (+) and negative (-) terminals of
the battery match the markings inside the compartment, replace the battery cover carefully. Do not
overtighten.
