INTRODUCTION
Thank you for purchasing a quality LUNA OPTICS®
product. With proper care and maintenance your
device will provide many hours of operation and
outstanding reliability. Please read this manual –it is your
key to enjoying this exciting and hi-tech product!
NIGHT VISION
Without getting too technical and confusing, let’s try to
understand how this device works and what it can and
cannot do:
1. Your night vision device works on the principle of
amplifying (intensifying) available light. The process is
called light amplification. A special tube inside the
device does the job –all you have to do is to power
the device on and the tube starts amplifying
whatever the light is available at the moment –
therefore it is important to understand that this device
is not suitable for daylight operation, since there is
already enough light available during daytime to see
without any additional help. Therefore, the first and
most important rule of any night vision device is –
never use it during daylight, or in any bright light
conditions, which allows you to see well with your
naked eyes!
2. Your night vision device operates with batteries.
Unlike a daylight binocular, where you see the image
due to light traveling through the glass and the
prisms, the night vision device works by projecting the
amplified image onto a screen. While the tube is the
crucial component of any night vision device, the
optical parts of the unit are also very important, as
they gather the light into the tube and bring the
projected image to your eye. Since the image is
projected on the screen, just like any TV, it has certain
limited resolution…so please
do not expect your night vision device to provide the
same crystal clear image, as you see through your
daylight binoculars –after all, you are using this device in
the dark environment, where normally your vision would

3
be very limited…oh, and another important point – all
night vision devices have green monochrome image –
why green? Because human eye can distinct most
details of the viewing image when presented in green
color…other colors do not show you everything…
3. Another very important notice –since your night
vision device amplifies available light thousands of
times –please be sure not to turn the unit on during
daylight or in a well-lit room –the image will be way
too bright for your comfortable viewing and it also
may permanently burn the tube inside the unit and
will surely void your warranty. Please note that for the
safety of this device it has a lens cover with a little
pinhole –to test the unit during daytime when you
bring your newly bought unit home, or in the shop
before you buy it. Please keep this lens cover on
during daytime –even if the unit is turned off. In
addition to the lens cover, as a protection, this unit is
equipped with automatic gain control, which
protects the tube from being exposed to bright light.
It is an effective way to escape most dangerous
situations however we urge you to still care for this
unit as if this protection is not present and please
avoid any prolonged exposure to bright light.
OPERATION:
Now that we’ve covered some of the basics of the
technology behind the night vision, let’s learn how to
operate your new device:

INSTALLING THE BATTERIES:
Your night vision unit operates on commonly available 2 AA-
type batteries.
To install the batteries, unscrew the battery compartment cover
(13), and install the batteries inserting the positive (+) end first.
Once the batteries are inside, replace the cover.
USING THE UNIT AS A HANDS-FREE GOGGLES SYSTEM:
IMPORTANT: FOR MODEL LN-EBG1-PRO PLEASE READ SECTION
“MENU SWITCH” ON PAGE 9 ENTIRELY PRIOR TO USING YOUR
GOGGLES WITH THE HEAD-MASK!
Your night vision bi-ocular can be used on a head-mask,
providing hands-free operation. Mounting is easy and
convenient:
1. Slide in the rail of the head-mask into the pathway
located on top of the unit near the Momentary Switch
button.
2. Tighten the wheel of the release mechanism (2)
(Please note that you may not need to slide the rail all the way
into the pathway –make sure that the distance between the
bi-ocular eyecups (5) and your eyes is comfortable –if it is not,
loosen the release system wheel and while pressing the release
button, slide the unit inward or outward until your eyes are
comfortably positioned next to the eyecups)
3. When goggles are not needed, you may conveniently
flip-up the entire binocular by pressing the flip-up
button (3) with your index or large finger while grasping
onto the body of the bi-ocular with the rest of the hand
and pulling the body upwards. Repeat the procedure
in reverse way to flip the bi-ocular down
4. To completely remove the bi-ocular from the head-
mask, loosen the release wheel and while pressing on
the release button, slide the unit outward

6
TURNING THE UNIT ON AND OFF:
Your night vision unit has a
special power and IR switch
(10), which allows you to easily
switch between ON and OFF
modes, while protecting you
from accidentally switching on
the IR illuminator. To turn the
unit ON, first remove the
objective lens cover (ONLY IN THE DARK!) and rotate the switch
by one dial to ON position. Look through the oculars –you
should see green glow. Even if the image is not yet sharp, the
unit is operating. To turn the unit OFF rotate the same switch
backwards one dial to OFF position. The green glow will
disappear if you turn the unit off correctly. Always replace the
objective lens cover after the unit is turned off and no longer is
in use.
FOCUSING THE UNIT:
To obtain the sharp image, you must first rotate each ocular
wheel (6) one-by-one in either direction, until you notice in
which position the image is at its best. After that, rotate the
objective lens (12) also until the image is at its best. You may
have to repeat the process again, until the image is sharp and
clear. Once the clear image is obtained, you no longer need
to adjust the oculars, just rotate the front objective lens to
adjust the distance to the object you are viewing.
ADJUSTING DISTANCE BETWEEN EYEPIECES:
Your LN-EBG1 (EBG1-PRO)
feature adjustable oculars
(eyepieces). This feature helps
to ensure the image appears
as one circle, which provides
the most comfortable
viewing, even when using
your goggles for a long period
of time. After you turn the
power on and after you adjust the focusing to the best possible
image, make notice of the image and see if it appears as one
single circle. If it does, then there is no need to adjust the
distance between the eyepieces. If the image appears as if
one circle is on top of another, then you need to either pull
apart the eyepieces or push them in together until the image
appears as one perfect circle (see image on the right).

USING INFRARED ILLUMINATOR:
Your night vision monocular is
equipped with two separate built-
in Infrared illuminator lights. The
Infrared light operates in a
spectrum, which is normally
invisible to a naked human eye,
however with the help of the tube,
located inside the unit, you will see a beam of light when
looking though the ocular lens. This Infrared light is here to assist
you in especially dark conditions, where there is not enough
light for the tube to amplify.
The first illuminator (IR1) (see insert image on the right) operates
on wavelength of 860nm and
provides close-up illumination while
being completely invisible to the
naked eyes and animals (even if
looked directly at the illuminator
lens).
Second illuminator (IR2) (see insert image on the right) operates
at a wavelength of 805nm and provides distant illumination.
This illuminator light can be seen if looked directly at the
illuminator lens, however its beam of light is still invisible to the
naked human eyes.
To turn the close-up Infrared
illuminator (14) ON, first make sure
the unit is ON then rotate the
Power Switch (10) to the IR1
position. To do that, you must
gently pull the top slide lever of
the switch with your index finger
and then rotate the switch one
dial. When looking through the ocular lens, you will notice a
faint green indicator light at approximately 6 o’clock position
outside of the field of view –this is to remind you that the
infrared light is on. To turn the infrared light off, rotate the
power switch one dial back to ON position.

8
Please note that it is possible
to momentary turn the 805nm
illuminator on by pressing the
momentary IR button (7). This
button will only turn on the
distant illuminator (11), not the
close-up illuminator (14)
To turn the second (distant) IR illuminator (11), rotate the switch
one more dial to the IR2. Look through the oculars and you will
notice a faint red light indicator at approximately 7 o’clock
position outside of the field of view. This is an indication of the IR
illuminator working. The second IR illuminator is much more
powerful and will provide approximately 25-35yds of light beam
to assist your viewing in complete darkness. To turn the second
IR off, rotate the switch either one dial back to IR1, or two dials
back to ON position.
The second IR illuminator
comes with a removable
focusing head lens (see insert
image below) allowing you to
either narrow the light beam
(for increased distance) or to
spread the beam across the
entire field of view when
operating on shorter distances. Rotate the head lens gently
outward to narrow the beam, but stop rotating once you feel
the lens hit a barrier. Rotate the lens inward until full stop to
widen the beam. Your goggles are shipped with head lens
installed and we do not recommend to ever removing the IR
lens.
When using the infrared illuminator it is important to remember
that like a flashlight, it is brightest when used in short distances.
As the distance increases, the intensity of the infrared light
fades away.
AUTOMATIC GAIN CONTROL AND PROTECTION SENSOR:
Please note that the unit is equipped with the special Auto-
Gain control, which would not
allow you to turn on the unit
without the lens cover in a well-
lit area, as well as will protect
your unit in case of an
accidental, or sudden exposure
to a bright light. Please note
that even though this is an

9
effective protection source, we at Luna Optics still strongly
recommend avoiding any such exposures to bright light,
especially prolonged ones in order to preserve the full life of the
tube. In addition to the gain control, you may choose to
activate the additional light protection sensor by rotating the
Menu Switch (8) to P position.
MENU SWITCH (PRO model only!):
Your night vision goggles come
with special Menu Switch (8)
which allows you to select 4
different levels of operation:
The default selector level is L+P, which provides manual
operation without head-mask and relies on auto-gain
feature to protect the unit from excess light. It is
recommended to switch to this level when using the
device as hand-held binocular (not on the head-mask)
and at the nighttime when risk of bright light exposure is
limited.
Next level is L–it is used when goggles are mounted on
a head-mask and provides an automatic power
shutoff when goggles are flipped up and automatic
power on when goggles are flipped down. This level
can only be used while unit is mounted on the head-
mask –the unit will not turn on if the menu switch is at
this level while using the device as hand-held
binocular.
Next level is ALL and it is identical to level Lexcept it
turns on the light protection sensor in addition to the
automatic gain control. This level is only useful when
mounted on the head-mask and a risk of bright light
exposure exists.
Last level is P, which turns on the light protection sensor
in addition to the gain control, providing extra level of
light protection especially in situations when you are
suddenly exposed to the excessive and dangerous
amounts of light. This feature immediately shuts off the
unit in such situations. It is recommended to switch to
this level while using the device as a hand-held
binocular and if risk of bright light exposure exists.

EXTERNAL POWER SUPPLY (PRO model only!):
It is possible to connect an
optional external power supply
to the goggles in order to
operate them during extreme
cold of greater than minus 10
degrees Centigrade. Please
inquire about the external
power supply availability from
your local dealer or write to us at [email protected]
NITROGEN GAS FILLING (PRO model only!):
It is possible to fill your LN-EBG1-
PRO with dry air or nitrogen gas
to prevent lens fogging in
extremely cold temperatures.
Please inquire about the
nitrogen gas filling kit from your
local dealer, or you may buy an
aftermarket kit, or write to us at
[email protected]
DEHYDRATOR CARTRIDGE:
Your LN-EBG1 (LN-EBG1-
PRO) is equipped with a
special cartridge, which
allows you to remove any
moisture from the unit in the
unlikely event of
uncontrolled
depressurization. (See
image on the right). Each unit is shipped with an additional
replacement cartridge, which can be found in the front
compartment of the carry case.

TROUBLESHOOTING:
1. Unit does not turn on:
a) please check if the batteries are inserted
according to the diagram
b) please make sure the batteries are fresh
c) make sure the Menu Switch is in L+P mode (when
not attached to the head-mask), or in L mode
(when attached onto the head-mask)
2. Unable to obtain sharp and clear image:
a) you may need to repeat the process of rotating
each ocular and objective lens several times
until you get a good feel of it
b) You may be viewing an object that it too close –
the minimum focusing distance is approximately
25cm or 10 inches
c) You may have dirty objective or ocular lens –you
may clean them with soft lens cleaning cloth
3. There are black dots (specs) in the field of view:
THIS IS NORMAL –BLACK DOTS ARE MICROSCOPIC PARTICLES
INSIDE THE TUBE AND RESULT FROM THE TUBE MANUFACTURING
PROCESS, WHICH IS NEVER COMPLETELY SPEC-FREE
IMPORTANT INFORMATION:
NEVER:
1. Intentionally turn on the unit without lens cover during
daylight or in a well-lit area
2. Allow laser beam or projector light to hit the objective
lens without the lens cover on.
3. Try to disassemble the unit by yourself or by anyone
who is not our authorized technician. Doing so may
result in injury and will void any warranty claims
4. Leave the batteries inside the unit for a long period of
time –the batteries may overheat and leak, which will
render the unit inoperable and will void the warranty
5. Submerse the unit into water –the unit does have
water-resistant protection, but is not submersible on
any depths for any period of time
