INSTRUCTION MANUAL
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 condition, 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 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 hundreds 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 lens covers 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 these lens covers on during daytime –even if the unit is turned off.
INFRARED ILLUMINATOR
Your night vision monocular is equipped with a built-in Infrared illuminator light
(8). This light operates in a spectrum, which is normally invisible to a 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.
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 BATTERY:
Your night vision unit operates on one 3V CR123 Lithium type battery.
To install the battery, remove the battery compartment cover (5), located on the
back of the unit by rotating the cover counterclockwise. Install the battery
according to polarity with positive (+) side going into the compartment first.
Once the battery is inside, replace the cover by rotating the cover clockwise until
stop.
TURNING THE UNIT ON AND OFF:
Your night vision unit has one-touch push-buttons. To turn the unit ON, first
remove the objective lens cover (ONLY IN THE DARK!) and press the system
power button (3) until the little green light indicator (7) located on the top of the
unit near the power button lights up. Look through the ocular (eyepiece) –you
should see the green glow. Even if the image is not yet sharp, the unit is
operating. To turn the unit OFF, press the power button again and make sure the
green light indicator is off. The green glow will continue for up to several
minutes, depending on the outside light conditions. This is normal. 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, first rotate the ocular focusing wheel (4) in either
direction, until you notice in which position the image is at its best. Then rotate
the objective lens focusing wheel (1) until you are able to obtain the best possible
image. 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 ocular.
Just rotate the objective lens to adjust to the distance of the object you are
viewing.
USING INFRARED ILLUMINATOR:
To turn the Infrared illuminator ON, press the Infrared illuminator button (2) until
the red light indicator (7) is on. To turn the infrared light off, press the same
button again and make sure the red light indicator is off.
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.
TROUBLESHOOTING:
1. Unit does not turn on and the light indicators are off:

a) please check if the battery is inserted according to the marking
inside the compartment cover
b) please make sure the battery is fresh
2. The light indicators are working, but you cannot see the image:
a) you may be turning the unit on in a dark area with the lens cover
still on the unit
b) You may need to turn on the infrared light
c) please make sure the battery is fresh –it takes a lot less power to
turn on the light indicator, than the entire unit
3. Unable to obtain sharp and clear image:
a) You may need to repeat the process of rotating 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 1.5m or 4.5 feet
c) You may have dirty objective or ocular lens –you may clean them
with soft lens cleaning cloth
4. The unit is turned off, but the green glow is still on:
THIS IS NORMAL –THE GREEN GLOW WILL FADE OUT WITHIN
FEW MINUTES
5. 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. Turn on the unit without lens cover during daylight or in a well-lit area
2. 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
3. Leave the battery inside the unit for a long period of time –the battery
may overheat and leak, which will render the unit inoperable and will
void the warranty
4. Submerse the unit into water or operate the unit during heavy rain
downpours
