!WARNING!
Do not operate this device until you
are familiar with the contents of
this manual. Keep this manual in a
safe place for future reference.
This Night Vision Device should
only be used during night or low
light conditions. It contains a light-
sensitive image intensifi er tube
that can be damaged if exposed to
excessive light. To prolong tube life
and avoid damage, do not turn the
unit on in daylight without the pro-
tective cover.
This Night Vision Device is
equipped with a built-in IR illumina-
tor that can be seen by other Night
Vision Devices when it is turned on.
Use this feature with caution.
This device will not show the dif-
ference between colored lights. It
produces only a green viewing im-
age. When color differentiation is
needed, verifi cation with unaided
eyes is recommended.
All Image Intensifi ed Devices re-
quire some light to operate such
as moonlight or ambient starlight.
Night vision devices will not pen-
etrate smoke, fog, rain, or heavy
snowfall. Cloud cover and tree
shadows will reduce the effective-
ness of this device.
Do not operate this Night Vision
Device in a potentially explosive
environment near gasoline fumes
or other volatile materials. This is a
high voltage electrical device.
Do not disassemble, puncture, re-
charge, or expose the battery to
fi re or high temperature. Doing so
may result in an explosion and re-
sulting chemical burns. When the
device is not in operation for a pro-
longed period, remove the battery
from the device and keep it sepa-
rately in a cool and dry place.

DESCRIPTION OF D-112
The D-112 has a black aluminum body (1). Permanently affi xed in this body are the IR illuminator
(8), image intensifi er tube, battery compartment (9), and rear eyepiece lens assembly (4). The front
lens (2), eyecup (6), and hand strap (12) are removable from the unit.

OPERATION
1. Battery Installation
!WARNING!
Prior to installing the battery make
sure that day time protective cover
is fi tted over the lens. Excessive
light can damage intensifi er module
and void warranty
2. Controls
a. ON/OFF Switch (8). Turn this switch clockwise
once to turn the unit ON. Turn it counterclockwise
to turn the unit OFF. Check the battery for the
required 3V current if the unit fails to turn on.
b. IR illuminator operation (8). IR illuminator is intend-
ed for providing additional illumination in especially
dark conditions. Use this feature with caution since
active IR illuminator can be seen by other night
vision devices. Turn switch clockwise twice to the
IR position. Rotate switch once counterclockwise to
the ON position to turn the IR illuminator OFF. IR
illuminator cannot be turned ON when the main unit
is turned OFF.
c. Focusing the image. Looking at the object, ro-
tate the eyepiece (4) until the sharpest image is
achieved. Adjust the front objective (3) to achieve
the sharpest image for varying distances. Adjust
the eyepiece focus again if needed. Once the eye-
piece is set for your eyesight it does not need to
be refocused for differences in distance. Only front
objective has to be adjusted in order to achieve
maximum resolution.
NOTE: The image will be seen only when the
objective lens and eyepiece are properly fo-
cused. The objective focus lens focuses on the
6
objects at varying distances and eyepiece focus
adjusts to the individual eyesight. These adjust-
adjusts to the individual eyesight. These adjust-
ments operate independently and must be made

separately

NIGHT VISION CHARACTERIS-
TICS
Monochromatic Image
Night Vision Devices produce a monochromatic
image. You will not be able to see any differ-
entiation between colors. In particular, red and
green lights will both appear green. Take care to
verify color differences with unaided vision. Ex-
ercise extreme caution when operating aircraft,
ground vehicles, or marine vessels while using
night vision equipment.
Color Sensitivity
Night Vision Devices are more responsive to
red and white lights than green and blue lights.
Because of this, distant red and white lights may
appear closer than green or blue lights. Exer-
cise extreme caution when using these lights for
navigation. Periodically verify the distances to
these lights with your unaided eyes.
Extreme Darkness
Night Vision Devices are effective under most
dark conditions including overcast starlight.
They are not practical in an extremely dark en-
vironment such as in a tunnel where there is no
natural ambient light. Without suffi cient ambient
light, the operator may notice pinpoint-size spar-
kles (scintillation or noise) in the image area.
These sparkles are small amounts of energy
generated inside the image intensifi er that strike
the phosphor screen and are an indication that
the device is working.
Contrast Reversal
Night Vision Devices detect light that cannot
be seen by the human eye. This light is often
referred to as being in the near-infrared light
spectrum. The existence of this light and the
manner in which it refl ects is not normally visible
to the naked eye. For this reason, objects that
normally appear lighter than their surroundings
may appear dark against a light background. In
addition, the output image of the Night Vision
Device is dependent on the refl ective quality
of the objects the operator sees in the viewing
area. Objects that appear light during the day
but have a dull surface may appear duller when
viewed through a Night Vision Device. All of
these factors must be taken into account when
10
utilizing a Night Vision Device for observation or
navigation purposes.
Depth Perception
Night Vision does not present normal depth
perception. Use extreme caution when using a
Night Vision Device where reliance upon depth
perception is important.
Fog and Rain
Night Vision Devices are very responsive to
refl ected ambient light; therefore, fog or heavy
rain can refl ect too much light toward the Night
Vision Device and may seriously degrade its
performance.
Honeycomb
This is a faint hexagonal pattern throughout
the image area. This effect is more noticeable
under high light conditions. Do not be concerned
- the honeycomb effect is an inherent character-
istic of all high-amplifi cation night vision systems
that incorporate a microchannel plate in the
intensifi er.
Black Spots
These are cosmetic blemishes in the image
intensifi er. They do not affect the performance
or reliability of a night vision device and a num-
ber of sizes are inherent in the manufacturing
process.
Image Intensifi er Life
Night Vision Devices are designed to be robust.
The image intensifi er tube, however, does not
have an unlimited lifetime. The life of the image
intensifi er is dependent upon the amount of
use. Under normal operating conditions, it will
provide reliable performance for an extended
period of time.
MAINTENANCE
Optics
Always clean the optics with a suitable optical
cleaning cloth. Do not use detergents or exces-
sive moisture to clean any part of the Night Vi-
sion Device.
Battery/Battery Compartment
Any Night Vision Device that is to be stored for a
long or undetermined amount of time must have
the batteries removed.
