GEN-2 HD DIGITAL TECHNOLOGY
DAY & NIGHT MONOCULAR
INSTRUCTION MANUAL
IMPORTANT: Please read this manual in its entirety
prior to using this device!

DIGITAL NIGHT VISION:
1. Your night vision viewer operates with batteries. Unlike a daylight
binocular, where you see the image due to light traveling through the
glass and the prisms, the digital night vision device works by
projecting the image onto an LCD screen. While the CMOS sensor and
the LCD display are the crucial components of your viewer, the optical
parts of the unit are also very important, as they gather the light into
the CMOS sensor and then bring the projected image from LCD screen
to your eye. Since the image is projected on the screen, just like any
TV, it has certain limited resolution, so your digital night viewer
cannot provide the same crystal clear image, as you see through your
daylight binoculars.
2. Another important point –your digital night vision viewer has full
color image during the day and option of color / night vision green /
black & white images when operating IR illuminator –why? Because
full color image sometimes washes out the details in the dark and will
not be as effective as monochrome image during nighttime
conditions. The night vision green color was chosen because green
color shows more details than any other color in the palette and black
& white image is especially useful when reading text or building signs
or car plates.
3. Your digital viewer is intended for operation during daylight and
nighttime hours. Please note that during daylight you will have to
reduce the brightness level of the unit to prevent the image from
becoming totally washed out. You should also utilize Color Enhancing
Filter, supplied with the unit for daylight operation in order to view
more vibrant colors.
4. For more details on how to operate your viewer, please read this
manual completely to ensure proper operation.

INSTALLING THE BATTERIES:
Your night vision unit operates on two 3V Lithium type batteries, known as
CR123A type commonly available in Electronics/Camera/Convenience stores.
NOTE: it is possible to use rechargeable batteries, but please make sure each
battery peak voltage is equal or less than 4.2V. You can charge the
rechargeable batteries via any common RCR123 battery charger.
WARNING: batteries supplied with the unit are not
rechargeable –do not charge or recharge these
batteries!
WARNING: it is prohibited to charge any batteries
inside the unit or have batteries inside the monocular
while operating it from wall outlet or car adapter!
To install the batteries, unscrew the battery compartment covers (3), located
on the back of the unit (one on each side below the ocular (2) and install one
battery into each compartment inserting the positive (+) end first. Once the
batteries are inside, replace the covers by rotating them all the way to the end
(do not over-tighten!).
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 and press the power button (12) once and
immediately release it. The green light indicator located on the back of the unit
should light up. Look through the ocular –you should see the Welcome screen
for a few seconds, followed by image. Even if the image is not yet sharp, the
unit is operating. To turn the unit OFF, press and hold the power button for 2
seconds. The image 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 to protect the lens.
IMPORTANT: When turning the unit ON it is normal to see some image
flickering, as the components warm up to display the image. This is normal and
does not affect the unit. If the flickering continues after 5-10seconds, please
try to decrease the brightness of the image by gently pushing the Brightness
Wheel (14) to the left.
OPERATING FROM EXTERNAL POWER SOURCE:
DC ADAPTER: Your digital viewer can also operate from a common wall outlet
with the use of the plug adapter (included). Insert the adapter cord into the DC
Output (8) and connect adapter to the wall outlet. IMPORTANT: Always
remove the batteries prior to operating the unit from wall/car outlet!
5V/2A POWER BANK: Your digital viewer can also operate from a common
charging 5V Power Bank. Please make sure each output on the Power Bank is
rated at a minimum of 2A. Connect the Power Bank to Micro-USB input (16).
SETTING UP DATE AND TIME:
As your viewer has capability to take images and record video, time and date is
automatically stamped onto each image and video recording. To set the
correct date and time, please follow this procedure:
Turn the unit ON. After image appears, press IR Button (13) and hold it for 2
seconds to activate the menu. Scroll until Date/Time function with Image
button (11) and select it by momentarily pressing IR button (13). Default date
format is DD/MM/YYYY. To adjust the numbers, press Image Button (11) either
in + or –direction. To switch between date/month/year, press IR button
momentarily. After Date is set, adjust the time. Time is in 24hr format, so
13:00 is 1pm; 17:30 is 5:30pm and so on. As with the date, changing hours and
minutes is done with Image button (11) either + or –and moving between
hours and minutes is done via IR button (13). Once the time is adjusted you
may choose to change the date format to MM/DD/YYYY or YYYY/MM/DD
according to your preference. Once you are finished setting date and time, you
must confirm your setting by pressing REC button (9).
IMPORTANT: in order to preserve the set date/time do not remove the dead
batteries from the unit until you are ready to replace them with the new set,
then replace the old batteries with new set as quickly as possible and the
date/time will be preserved.

FOCUSING THE UNIT:
To obtain the sharp image, you must first rotate the objective lens (1) in either
direction, until you notice in which position the image is at its best. After that,
rotate the ocular (2) 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 ocular, just rotate the front
objective lens to adjust the distance to the object you are viewing.
BRIGHTNESS ADJUSTMENT:
Your digital viewer is equipped with dual brightness control. An automatic
brightness control sensor adjusts the image brightness according to the
available ambient light. In addition a toggle brightness adjustment wheel (14)
allows you to fine-tune the image brightness depending on the ambient light
conditions. Please note that during daylight you will need to tone the
brightness down to avoid image flickering and to preserve the battery life.
During nighttime you could increase the brightness all the way up, however
when utilizing built-in or external IR illuminator, you may need to tone the
brightness down a bit. Each rotation of the wheel in either direction will
decrease or increase brightness by one level.
ELECTRONIC IMAGE MAGNIFICATION ZOOM:
Your unit is also equipped with electronic zoom function, which allows you to
change image magnification from 5x to 25x on model LN-G2-M44 or 6x to 30x
on model LN-G2-M50. To increase the image magnification press the IMAGE
button (11) on the + side and look into the ocular –you will see the image
magnification increase. At the minimum level (1.00) the image magnification is
5x (6x for model LN-G2-M50); at the maximum level (5.00) the image
magnification is 25x (30x for model LN-G2-M50). You can see the zoom level
either in the left or right lower corner of the image screen (depending on the
software version) once you start pressing the IMAGE button on the + side. To
decrease the image magnification, press the IMAGE button on the –side.
USING INFRARED ILLUMINATOR / IMAGE COLOR OPTIONS:
Your digital viewer is equipped with a built-in powerful Infrared illuminator
light (10). This light operates in a spectrum, which is normally invisible to a
human eye, however with the help of the CCD sensor, located inside the unit,
you will see a beam of light when looking though the ocular lens. Since the
CCD does not actively amplify the available light, you will need to utilize the IR
illuminator often in the nighttime conditions.
To turn the Infrared illuminator ON, press the Infrared illuminator button (13)
momentarily –the illuminator will turn on and red LED light indicator located

next to the eyepiece will light on, indicating the IR illuminator is operating. The
image will remain full color. To switch image to night vision green –press IR
button again. To switch image to B&W press the IR button again. To turn the IR
illuminator OFF press the same IR button again once. The red light indicator
will disappear when the IR illuminator is properly turned off.
It is also possible to utilize different color image options without the use of IR
illuminator by selecting either Black & White or Sephia (NV green) option in the
main menu. Selection is done with the long IMAGE button (11) and
confirmation is done by short-pressing the IR button (13). Please note –after
selecting either B&W or Sephia option this way, once you activate the IR
illuminator, this option will be disconnected automatically.
When using the infrared illuminator it is important to remove the red daylight
color enhancing filter and also remember that like a flashlight, the IR
illuminator is brightest when used in short distances. As the distance increases,
the intensity of the infrared light fades away.
Extended range IR illuminators are available (model LN-EIR-2, or LN-ELIR-2),
which can be mounted into the side accessory mount socket (4). The thread is
a standard ¼” type and will accept any accessory with mounting screw of that
size.
TAKING PICTURES AND RECORDING HD VIDEOS:
WE STRONGLY RECOMMEND MOUNTING YOUR DEVICE ONTO A
STEADY TRIPOD WHEN RECORDING VIDEO OR TAKING STILL IMAGES –
PARTICULARLY WHEN WATCHING DISTANT OBJECTS AND/OR
UTILIZING ZOOM FUNCTION
Your digital viewer has the ability to take pictures and record HD videos onto
the external Micro-SD card. 8GB card is included
with your unit and it is already installed into the
SD-card slot. The Micro-SD card can be upgraded
up to 128GB, which is especially useful if you plan
to record a lot of videos. To change the SD-card,
open the SD-card/USB compartment (7) by
carefully sliding the latch to the right. The door
will pop open as you see on the image on the
previous page. Remove the included 8GB card by pressing onto its end. It will
pop out of its slot (15) as shown on the image. Gently remove the card and
replace it with the new one by pressing it straight forward until it is securely
locked in the slot. Close the compartment door and lock it by sliding the latch
to the left.

To record a video, focus the unit onto the object and press REC button (9) once.
The system will start recording. Please note that the video is being recorded in
Full-High Definition (1080p) and in the Widescreen format (16x9). To pause
video recording press PIC button (10) once. To resume video recording press
PIC button again. To stop recording, press Power button (12) once. During
recording it is still necessary to re-adjust the focus if you wish to record
different objects, located at different distances. Please be aware that actual
video recording quality is significantly higher than what you will see through
the viewfinder –to see recording in widescreen HD format please remove the
micro-SD card and play it on your Blu-Ray player or computer.
NOTE: during daylight video-recording is 60fps, during nighttime it is 30fps.
DATA VIEWING AND DATA TRANSFER OPTIONS:
It is possible to view the images and videos directly on the unit’s micro-display.
To do so, while the unit is operating press the Power button (5) momentarily
just once. You will be able to switch between images and videos by pressing
IMAGE button (4) in either + or –direction. To play the recorded video, press
PIC button (3) once. To stop playing video press PIC button again. To exit
picture/video viewing mode and to come back to the active image mode, press
Power button (5) briefly just once. Please note –if you press and hold Power
button, your unit will shut down and would need to be reactivated again by
pressing Power button once.
You can connect the unit directly to the computer via USB connection by
utilizing the micro-USB connector (16). To do so, first connect the micro-USB
part to the unit, then connect the standard USB part to the computer. Look
through the eyepiece –choose MASS STORAGE option via the IMAGE button
and confirm your selection with either PIC or REC button (depending on the
software version). Once connected to the computer, the software will
download automatically and you will be able to open and transfer all of your
SD-card files onto your computer.
Alternatively, you can remove the micro-SD card from the monocular and use it
in the included USB flash drive adapter to transfer data to your computer. If
your computer has a direct micro-SD slot, you can insert the card directly to the
slot bypassing the above options. It is also possible to utilize the full-size SD
card adapter (not included with monocular).

CHOOSING CORRECT ISO (SENSITIVITY) SETTING:
Your digital monocular comes with 5 user-selectable ISO (sensitivity) settings,
plus an AUTO mode. All units come with AUTO mode as a default setting and in
most conditions this mode is the best choice for viewing and recording. In
certain conditions where extra sensitivity is desired (such as Sky Watching
where small light objects need to be constantly seen) it is better to select one
of the highest ISO settings (between 1600 and 6400) for constant sensitivity,
which prevents any sudden bright light source to lower the overall system
sensitivity. To choose the ISO setting, access the menu by long pressing the IR
button (13) and selecting desired mode with IMAGE button (11) and confirming
with IR button (13)
CONNECTING TO EXTERNAL VIDEO SOURCE:
You can connect your device to the TV/VCR/DVR via the RCA-type video cord
(included with your device). Connect the small end of the Video cable to the
Video Output (5) and then connect to the TV/Recorder. . NOTE –if you live
outside of the USA, you may need to switch the Video Output from NTSC to
PAL by accessing the menu (Press IR Button for 2 seconds and when Menu
appears select Video Format with Image button (11) and activate it with IR
button (13). Switch between NTSC and PAL formats by pressing the Image
Button and confirm your setting by pressing IR or REC button (depending on
the software version).
WI-FI LINK INSTRUCTIONS:
1. Download “ROADCAM” app on your Android
phone/tablet or on iPhone/iPad
2. Press PIC button for 3 seconds to activate your

RE-FORMATTING 64GB & 128GB MICRO-SD CARDS TO FAT32
FORMAT:
Any micro-SD card above 32GB needs to be re-formatted from EXFAT format to
FAT32 format, which is the format of the night vision monocular (and many
other consumer electronics). Please note that FAT32 is the most widely used
format and is also considered the most reliable format.
In order to re-format the card you must run it through a 3rd party provider. We
suggest using Disk Partition. While nearly all of the providers would want you
to buy their upgraded versions, you can just download their basic free version
and it would be sufficient to re-format the card. Disc Partition seems to be the
most simple and hassle-free provider we could find:
https://www.disk-partition.com/download.html
Download the “Standard Free” version and follow all the download
instructions.
Once downloaded, open the program and insert the micro-SD card
into the computer.
Highlight the correct disc by single-click and then choose on the
bottom left side of the menu to “Format Partition” (alternatively right-
click on the highlighted disc and choose the same function). A pop-up
window will appear. You can label your partition (such as “Luna Optics
Monocular” or any other name you desire (it’s optional) and then
make sure to select “FAT32” as the File System. Then click “OK”.
Once the format is finished, click on “Apply” located in the most upper
left corner. You must select “Apply” otherwise the formatting is not
finished.
You card is now formatted, but before you can use your 64GB+ card in
our digital night vision product you must also format the card inside

the product. To do so, insert the card into its slot, turn the night vision
on and through the menu find and select “Format”, then select “OK”.
Once the card is formatted inside the night vision device it is now
ready to use.
