APPLICATION
The ATN Night Tiger Bi-ocular was designed for prolonged medium to long-range nighttime
viewing. Utilizing a high quality US made 2
nd
or 3
rd
generation light intensifier tube the Night
Tiger provides the user with a bright and sharp image for scanning dark terrain. A dual eye view-
ing system combined with a fast 3x front lens, lets you use your Night Tiger comfortably for long
viewing sessions while giving you a wide field of view to easily cover your surveillance area.
Whether you are on patrol, a stakeout or observing wildlife the Night Tiger is one of the best
surveillance night vision devices made.
The Night Tiger Night Vision Scope is a complex opticoelectronic system for individual use.
The device consists of the objective lens assembly, eyepiece and the body. The body contains
a image intensifier tube assembly with an integrated high voltage power source and the bat-
tery housing.
Objective lens protective cover (not shown) is intended to protect the objective lens from dust
and scratches. It also will act as a daylight filter, allowing you to test the scope in daylight or
other bright light situations. The pinhole in the center of the protective cover allows the user to
check the operation ability of the device in daylight conditions.
NOTE:
Do not test the scope in daylight conditions even with the daylight filter/lens cap on for
more than ten (10) minutes.
OPERATION
• Take the monocular out of the case.
• Install the battery into the housing with the polarity order as shown on the scope. Battery
Type: 3 Volt Lithium, #CR123A .
• Press button marked
O/I
to turn the unit on with the protective lens cover still attached to
the lens.
Do not turn the unit on in the daytime without the protective lens cap on.
You
should see green glow in the eyepiece.
• Observe the scene and adjust the diopter for optimal image clarity.
• You may now enter a dark environment or simply shut the lights off in order to darken the room.
• Next, remove the lens cap/daylight filter. Adjust the front lens for the distance of the focus.
You should not have to readjust the diopter.
FOCUSING
To focus the Night Tiger, first you will need to
adjust the diopter. Simply turn the diopter clock-
wise until it stops. Then, while looking throught
the diopter at an object, slowly turn the diopter
back counter clockwise until the grain in the
image is sharp.
NOTE:
We suggest that you focus the diopter
during daylight with the filter on.
Next focus the front lens until the image and the
grain are both sharp. When you are in low-light
conditions and the daylight filter is off, you may
focus the front lens to receive sharp image, the
diopter should not be adjusted.
NOTE:
The front lens should be readjusted as
you view objects at different distances.
