Safety
Before using your OMAX product, please read the following safety precauons carefully to avoid causing damage to the device or
injury to yourself or others.
Use only 3.7V 18650 lithium-ion baeries. Use of other baeries may cause damage to the device or injury to yourself or others.
Turn o power if the instrument exhibits unusual or dangerous behavior such as eming smoke or unusual odors. These can be
indicaons of electrical problems, in which case the instrument should be disconnected from any power source if safe to do so. Other
indicators can be a loud buzzing sound or crackling. Contact OMAX to report such behavior.
Do not use around ammable liquids or gases. Electric instruments can ignite ammable substances which could result in an
explosion or re.
Avoid use in wet environments. Electrical components of the instrument can discharge when exposed to water, potenally resulng
in damage to the instrument, or injury to yourself or others.
Do not dismantle. Dismantling will void the warranty and can result in damage to the instrument, and potenal exposure to dangerous
materials or electric current.
Noces
OMAX reserves the right to change specicaons of the product at any me without noce. Connuous eorts are made to improve
performance and reliability, which can result in changes to design and compability. Please contact OMAX for any concerns regarding
such changes.

1. Preparaon
1.1 Baery Installaon
Important: only use 3.7V 18650 rechargeable lithium-ion baeries.
Do not remove the baery compartment cover while the device is powered on. Ensure the device is powered o before proceeding.
To open the baery compartment, press the baery cover tab toward the baery compartment, then li outward to remove the
cover. Posive and negave terminals are labeled inside the compartment. Orient the baery’s posive and negave terminals with
the compartment’s terminals. Once the baery is seated, replace the compartment’s cover.
1.2 The I/O Panel
The I/O (Input/Output) panel consists of a USB-C port and a MicroSD card slot. The panel is located on the scope’s right grip. To
access it, pull the tab on the le side of the protecve cover.
1.3 Charging the Baery
To charge the baery, use the supplied USB cable with a USB power source or charging adapter. Aach the cable’s USB-C plug into
the I/O panel’s USB-C port. Insert the cable’s Type-A connector into a charging adapter’s USB port. Plug the charging adapter into an
AC outlet to begin charging. An image of a charging baery will appear on the scope’s viewing screen showing the charging status.
When the status reaches full capacity, the charging cable can be disconnected.
1.4 Recording Media
This device uses MicroSD media (also called TransFlash or TF) for recording photos and videos. MicroSD cards up to 32GB may be
used to record and store les. In order to ensure proper performance, only cards with speed class 10 should be used.
To insert a MicroSD card, align the card with the card slot so that the card’s smaller end with the metal contacts are facing the slot,
and the printed surface of the card is facing up. Gently push the card into the slot. Be careful not to force the card, as this could
result in damaging the card and jamming the slot. When the card is fully inserted, there should be a click.
To remove the MicroSD card, push the card inward to acvate the release. The card will parally eject so it can be pulled out. Do
not remove the card while the device is recording, as this will result in loss of data.
2. Operaon
This NVB series night vision scope uses a highly-sensive digital imaging sensor to display live video on a viewing screen. The scope
can use ambient light and its built-in infrared lamp to view and record in sengs with lile to no light. The rear of the scope con-
sists of a viewing screen and a control panel, while the front of the scope consists of an objecve lens and an infrared light source.
2.1 The Control Panel
The control panel is located on the top of the device, above the screen. There are six buons which control power, switch recording
and exposure modes, capture images, and manage the device’s sengs.
2.2 Powering On/O
To power on the scope, press and hold the power buon for approximately 2 seconds. Once the screen displays an image, you can
release the buon. To power o the device, press and hold the power buon for approximately 2 seconds. Once the screen begins
to turn o, you can release the buon.
2.3 Focusing
While the night vision scope is powered on, a live image will be displayed on the viewing screen. To control focus, adjust the focus
ring located on the front le of the scope. Rotang the ring clockwise will focus closer while rotang the ring counter-clockwise will
focus farther.

2.4 Exposure Modes
This device has three exposure modes including a standard exposure mode and two night vision modes. When using the standard
mode, the IR lter cap should be closed to limit the amount of natural infrared light reaching the camera’s sensor. To switch to night
vision mode, press the exposure mode buon once. The live image will change from color to monochrome, and the camera sensor’s
sensivity will be increased. This mode can be used in dim lighng to maximize brightness. Press the exposure mode buon once
more to enable the infrared lamp. When using the infrared lamp, the lens’ IR lter cap must be opened to allow the infrared light
to enter. This mode can be used in complete darkness since the infrared lamp generates light which can be detected by the camera
sensor.
2.5 Exposure Value
The scope uses automac exposure compensaon to adjust image brightness. It is possible to oset the automac exposure using
the Exposure Value (EV) seng. The current seng is displayed on the boom right of the viewing screen. The default seng is EV-
A. By pressing the right arrow buon, the EV seng can be incrementally adjusted from EV-1 to EV-9 with EV-9 decreasing exposure
by the largest factor. Pressing the le arrow buon will adjust the EV seng to increase the exposure.
2.6 Digital Zoom
This device has a digital zoom funcon which can increase the magnicaon by up to 8X. The current magnicaon is displayed on
the boom right of the viewing screen to the le of the baery power indicator. To use the zoom feature, press and hold the le
arrow buon to increase the zoom level, or the right arrow buon to decrease the zoom level. While either arrow buon is held, a
blue bar will be displayed on the right side of the screen showing the zoom level.
2.7 Changing Recording Modes
The mode buon can be used to switch recording modes. Photo mode will be set by default. Press the mode buon once to switch
to Video mode. Press the buon once more to switch to Playback mode. One more press will return to Photo mode. Each mode can
be idened by the icon displayed in the top le corner of the screen.
