HIGH DEFINITION DIGITAL DAY &
NIGHT VIEWER
INSTRUCTION MANUAL
IMPORTANT: Please read this manual in its entirety
prior to using this device!

DIGITAL NIGHT VISION TECHNOLOGY:
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 OLED display screen. While the
CCD/CMOS sensor and the OLED 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 CCD/CMOS sensor and then bring the
projected image from the OLED screen to your eye. Since the image is
projected on the display 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
option of full-color, night vision green and black & white image –
why? Because, while full-color image is an excellent choice during
daylight, it 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 during nighttime.
3. Your digital viewer is safe to operate during daylight and
nighttime hours. IT IS NOT SAFE FOR YOUR EYES TO LOOK DIRECTLY
AT THE SUN THROUGH THIS PRODUCT! 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. (Filter is attached to
the front lens and also acts as a protective lens cover)
4. For more details on how to operate your viewer, please read this
manual completely to ensure proper operation.

INSTALLING THE BATTERIES:
Your device 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 (CR123R) but
please make sure each battery peak voltage is equal to or less than
4.2V
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! Use only approved CR123 battery
chargers for this operation.
To install the batteries, unscrew the battery compartment cover (6), and
install two CR123A batteries into compartment inserting the positive (+)
end first. Once the batteries are inside, replace the cover by rotating it
all the way to the end until the stop (do not use force or over-tighten!).
DAYLIGHT COLOR ENHANCING FILTER:
Your monocular is equipped with a unique daytime
color enhancing filter, which provides vibrant and
accurate colors rendition (digital image sensors are
known to distort colors and provide an unnatural
color image during daytime. The filter comes
attached to the objective lens and we strongly recommend keeping it
on during daytime use. During nighttime you will need to remove the
filter (by unscrewing it counter-clockwise). Please keep the filter in the
carrying case when removed from monocular to prevent accidental loss.

5
TURNING THE UNIT ON AND OFF:
Your night vision unit has one-touch push-buttons. To turn the unit ON,
press the POWER Button (4) momentarily once. The LED Power
Indicator (10) located on the back of the unit should light up in green
color. Look through the eyecup (8) –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. We suggest to always replace the daytime color filter
/ protective lens cover after the unit is turned off and no longer in use.
IMPORTANT: When turning the unit ON or when switching between
various modes (Video, Photo etc.) or when operating the unit with Wi-Fi
stream activated, it is normal to see some image flickering in the
display. This is normal and does not affect the unit. If the flickering
does not disappear once the affecting functions are no longer active,
please re-start the unit. If conditions persist, please contact us at:
[email protected] for assistance.
OPERATING FROM A USB POWER BANK:
Your digital viewer can also operate from the commonly available 5V
USB Power Bank chargers. Please make sure the output of the Power
Bank is at least 2A, as less powerful output may fail to power the unit
especially when the IR illuminator is activated. To connect the Power
Bank, open the Connection Area (11) rubber cover by gently pulling it
outward and then swing it counter-clockwise to the right and locate the
Micro-USB connector (11-b). Connect the small end of the USB cable
(included) to the connector and then connect the large end of the cable
into Power Bank output. You may need to activate the power bank first,
prior to turning the viewer on.
FOCUSING THE UNIT:
To obtain the sharp image, you must first rotate the Objective Lens
Focusing Wheel (1) in either direction, until you notice in which position
the image is at its best. After that, rotate the Ocular (Eyepiece)
Focusing Ring (5) 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 will no longer need to adjust the eyepiece,
just rotate the front objective lens to adjust the distance to the object
you are viewing.

6
SUPER CONTROLLER / MENU FUNCTIONS:
Your monocular features a unique and
user-friendly adjustment called Super
Controller (9). It incorporates various
operating functions and makes navigating
and adjusting menu functions fast, easy
and natural without having to take your
eyes off the eyepiece in the field. It is
especially useful when using in the dark
conditions where button location may be
particularly difficult. Super Controller
activates the Main Menu by pressing onto it for approx. 2 sec.
Once activated, all Menu navigation is done the following way:
-Scrolling through the menu contents: rotate the Super

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 onto the Super Controller
(9) and hold it for approximately 2 seconds to activate the menu. Scroll
until Date/Time function by rotating the Super Controller and select it

9
by momentarily pressing onto it. To adjust the numbers, rotate the
Super Controller in either direction. To switch between numbers, press
onto Super Controller 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 by rotating the Super
Controller and moving between hours and minutes is done by pressing
onto it. 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 can exit the menu by
pressing Super Controller (9) for approximately 2 seconds. Once set, the
time will be displayed on the bottom of the OLED image display.
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.
USING INFRARED ILLUMINATOR:
Your digital viewer is equipped with a built-in powerful Infrared
illuminator light (7). 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 (4) momentarily –the IR icon will appear on the bottom of the
display and red LED light indicator (10) located next to the eyepiece will
light on, indicating the IR illuminator is operating. The illuminator
intensity can be further increased by pressing the IR button (4) second
and third time (momentarily). The IR icon in the image display will
change colors from pink to orange to red, indicating the three different
power levels. After the red level (3rd and most powerful) the next
momentary press on the IR button will turn the IR off completely. The
red LED light indicator (10) will disappear when the IR illuminator is
properly turned 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.

10
Extended range IR illuminators are available (model LN-EIR-2, or LN-
ELIR-2), which can be mounted into the single (black) bottom accessory
mount socket. The thread is a standard ¼” type and will accept any
accessory with mounting screw of that size. If the black bottom mount is
utilized for tripod mounting, you can utilize any of the two gold sockets.
Please note that due to the monocular shape a special riser plate will be
required to mount our LN-EIR-2 or LN-ELIR-2 (please e-mail us at
[email protected] and request this riser plate if your extended range
illuminator did not come with it).
IMAGE COLOR OPTIONS:
-Normal mode displays images in full-color. This is preferred
mode for daytime use as well as when enough artificial light is
present (inside a well-lit room). If used during nighttime the
overall sensitivity of the image sensor will be significantly
reduced.
-B&W mode displays images in black and white. This mode is
particularly useful during nighttime city setting when it might be
important to read the street signs or automobile plates or
similar situations where highest contrast between light and dark
colors is necessary.
-Green mode allows you to experience image as seen with
traditional “tube” night vision devices. This mode is best utilized
at nighttime in the field / forest settings
IMPORTANT: PLEASE READ!
Due to the inherited limitations of any digital image sensor, video
refresh rate will be significantly slower during nighttime, resulting in
visible image lag/delay when using your monocular in the dark. It is
important to take the following steps to minimize this effect and ensure
the best possible image and video recording quality:
-During nighttime and in any dark condition always activate
built-in IR illuminator –it will provide extra light needed for the
image sensor to “speed up” its refresh rate and image delay will
be minimized.
-During nighttime you need to remove the daylight color
enhancing filter –it will block most of the Infrared light from the
built-in IR illuminator resulting in very dark image.
-Always try to utilize a quality tripod for any video recording
done at nighttime. This will ensure steady placement and will
minimize image delay when filming a moving object.

11
BRIGHTNESS ADJUSTMENT:
Your digital viewer is equipped with dual image brightness control. An
automatic picture optimization sensor adjusts the image according to
the available ambient and artificial light. In addition a manual Image
Brightness Button (2) allows you to fine-tune the image brightness to
the most comfortable level. Please note that during daylight you will
need to tone the brightness down to avoid image flickering and/or
washout 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 still need to tone the brightness
down. Each momentary press onto the IMAGE Button (2) will increase
brightness by one level until it reaches maximum level –then it will
reset to the lowest brightness setting.
TAKING PICTURES AND RECORDING HD VIDEOS:
Your digital viewer has the ability to take High-Resolution 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 See RE-FORMATTING 64 & 128GB
CARDS TO FAT32 FORMAT on page-14 for important instructions.
Your monocular has a multi-use CAMERA button (3). It can be used to
record video and capture still images. You can switch the function of
this CAMERA button by activating the Main Menu (long press onto
Super Controller (9)) and selecting Mode function and then select either
Video for video recording or Photo for still image capture. Please refer
to Page-6 for instructions on how to use Super Controller and Menu
options.
To take a still image, focus the unit onto the object you are viewing and
with a steady hand firmly press the CAMERA button (3) once. The
display will give a countdown (2-1) and then image is taken and is
automatically stored onto the SD card. All still images are taken at
4032x3024 resolution (12.2MP)
To record a video, focus the unit onto the object and press CAMERA
button (3) once. The system will start recording. To stop recording,
press CAMERA button once again. During recording it is still necessary
to re-adjust the focus if you wish to record different objects, located at

12
different distances. There are 4 different video recording resolution
options:
1. FULL-HD 1080P / 30FPS: Blue-Ray quality recording. Best for
recording in daylight with color filter on when highest video
resolution is necessary. Also good for recording at nighttime
without the color filter, when monocular is stationary on a
tripod and no sudden movements are expected
2. HD 720P / 60FPS: Excellent for daytime and nighttime
recording.
3. HD 720P / 30FPS: Daytime and nighttime recording.
4. WVGA 480P / 60FPS: DVD quality recording, great for space
saving mode where large amount of video is expected
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 access the main menu by
pressing the Super Controller for 2 seconds. Enter “Mode” menu and
choose “Playback”. As always, scrolling between functions is done by
rotating the Super Controller and function selection is done by short-
pressing the Super Controller. Once in the Playback Mode you will be
able to switch between photos and videos by rotating the Super
Controller and short-pressing Super Controller will activate any video
file. To exit the Playback Mode simply press Super Controller for 2
seconds.
You can connect the unit directly to the computer via USB connection
by utilizing the micro-USB connector (11-b). To do so, connect the
