OPERATING INSTRUCTIONS

The SENTINEL night vision riflescope is intended for observation and shooting at dusk or during
nighttime hours. It is a passive starlight device, and in most conditions does not require an artificial
or IR light source. The scope is built with a high performance Gen1 image intensifier tube. The
built-in IR illuminator enhances a viewing ability in environments of absolute darkness. Power
supply, with the voltage stabilization, works up to 70 hours using 2 AA batteries. Low batteries do
not affect aiming ability. Additional remote stabilized power supply was designed for optimized
power consumption, which ensures a consistent aiming point in conditions of continuous power
draw or drop in temperature.
The SENTINEL is a universal night vision scope, which is ideal for night observation and hunting.

USING THE SENTINEL

The SENTINEL was designed to provide many years of reliable service. To ensure longevity and
performance, it is necessary to follow all procedures and guidelines outlined in this manual.

Warning:

The SENTINEL is not recommended for use with cartridges producing recoil rating higher than
3700 joules or calibers in excess of 7.62/.300. The manufacturer's warranty will be voided if damage
is caused by caliber cartridges greater than 7.62/.300, hand made cartridges or shooting from a
smooth-bore barrel.

• Do not remove the lens cap in a lit area if the scope has been activated or if the eyepiece is

emitting a green glow.

• Exposure to bright light can damage the image intensifier tube (IIT).

• Do not remove the objective lens cover in a lit area immediately after using the scope. It will

stay activated for 20 minutes after the unit has been turned off.

• The scope has an IPX4 water resistance rating. It is water resistant and can be used in

inclement weather conditions.

• Do not attempt to repair or disassemble the scope!

• Clean the scope's optical surfaces only if necessary, and use caution. Remove dust and sand

by blowing air across the optic surface, then apply lens cleaning fluid for multi layered optics
onto a soft cloth or tissue and wipe carefully. Do not pour any fluid, including alcohol, onto
the lenses directly.

• The scope can be used in temperatures ranging from -30°С to +40°С. However, when it is

brought indoors from cold temperatures, wait 3-4 hours before using the unit.

• Consult a qualified gunsmith if there is difficulty attaching the scope firmly to a rifle or if

there is uncertainty about the right type of mount. The weapon mount can be deformed or
destroyed by shooting with a riflescope that is not mounted correctly.

• Regular maintenance of the scope will help keep the device free from malfunctions and

untimely wearing of parts and connectors.

Failure to observe these warnings will void the manufacturer's warranty.

BATTERY INSTALLATION

• Turn the knob of the battery compartment cover 90º counterclockwise (1) to match the red

dot on the knob with the red dot on the battery compartment cover.

• Remove the cover by raising it by its lug.

• Slide in two АА batteries so that the “+” and “-” match the polarity on the inner side of the

cover; rechargeable AA batteries may be used.

• Close the cover of the battery compartment cover and turn the knob of the cover

90º clockwise.

OPERATING THE SENTINEL

Warning: It is strongly recommended to test and operate the SENTINEL in dark conditions or
at night time.

• Install the batteries according to the directions in the section entitled “BATTERY

INSTALLATION”.

• Enter a dark environment.

• Remove the objective lens cap by sliding it up on top of the objective lens (2).

• Activate the scope by turning the power switch to the “ON” position (3); the indicator

will turn green.

• A red indicator means that batteries are low and the scope will be working with the IR

illuminator turned on for 30 more minutes.

• Select the color of the reticle, green or red, by pushing the button (5).

• Adjust the reticle brightness by rotating the switch (4).

• Please select an object of observation at a distance of approximately 100 meters (about

110 yards) away.
