Ork Hunter PVS-14 Night Vision Monocular User Manual
General information
Ork Hunter PVS-14 is a multifunctional night vision system that allows you to use it not only by holding it in your hands, but also by attaching the device to your head, helmet or weapon. At night, in the presence of moonlight and starlight, the monocular can be used for driving vehicles, shooting, conducting remote surveillance, reading maps, servicing machinery, providing first aid and other tasks. Using the head mount, the monocular can be fixed in the most comfortable position. The design of the device is compact, durable and equipped with a built-in IR illumination. The monocular can be used together with an optical sight, which will give it the function of night vision sight.
The kit includes: a night vision monocular, a head mount, an additional wide-angle lens, a battery, a protective case for transportation, an instruction manual, a tissue for cleaning the lenses, a warranty card.
Main Features
- Lightweight and durable waterproof case.
- A built-in spring in the battery cover makes it easier to screw on and improves contact with the battery.
- Fully adjustable head mount that can be adjusted to fit your head size.
- Automatic brightness control: when the ambient light changes, the brightness of the detected image will remain the same to ensure a stable observation effect and also protect the user’s eyes.
- Over-brightness protection: When the ambient light exceeds 40Lx, the device will automatically turn off after 10 seconds to avoid damage to the image intensifier.
- Low battery indicator: the green indicator on the edge of the eyepiece starts to blink when the battery is low.
- For power supply, you can use a 3V lithium battery (1 pc) or an AA alkaline battery (1 pc).
- Additional wide-angle lens included.

Operating Instructions
Put one 3V CR-123 lithium battery observing the polarity indications on the battery compartment (2) surface. Remove the protective cover (4) when it’s used at night or in low light condition.
NOTE!
To protect the image intensifier tube, keep the lens cap on the objective lens
when the monocular is not in use or when checked out in daylight conditions.
Turn on the device by pushing operation button (1) and moving it to ON position. After this, you can start observing the scene through the eyepiece (5). The greenish-lit screen of the image tube means that the device is working normally. A green light appears in the edge of eyepiece at the same time and it serves as the power indicator as well as low battery indicator. If the indicator light starts flickering, it means the battery is running low.
Activate the IR illuminator (8) by another pushing button (1) and moving it to IR when the monocular is working in the conditions of extreme low light or total darkness
NOTE!
The IR-light from the illuminator can be detected by others that are using
night vision devices.
Focus the objective lens (3) by rotating the objective lens ring for sharper image of viewed object. Adjust eyepiece (5) by rotating the eyepiece ring for sharper image of intensifier screen.
You may focus the IR light for additional distance by placing the focusing
lens of the IR illuminator (8).
This will extend the range the useful range of the IR.
The light detector (9) can detect the surrounding luminance; the device will be shut off automatically when the ambient light exceeds 40Lx in 10 seconds. When you finish observing, push the operation button (1) and move it to OFF, then the device stops working.
Head mount installation
Put the head mount on the head. Adjust all the straps, at the end fix the chin strap with velcro. Remove the head mount from the head and install the device on it.
Installation and adjustment of the night vision device
Insert the device with the mounting part into the bracket C as shown in the figure above. Tighten the bracket with ring A.
To raise the device to the upper position or lower it, press button B.
Precautions
Do not disassemble the device by yourself!
It’s better to use a device under +5°C to +40°C.
After the device usage in temperatures below zero, wait at least 3 hours at
room temperature, to avoid condensation accumulating on the internal lens
surfaces and the consequent fogging caused by extreme temperature differences.
Keep the device in a soft carrying bag, ventilated and dry place with a temperature which does not exceed +15°C. Keep away from the heating devices and avoid direct sunlight and high humidity which does not exceed 70%.
The device should be used at nighttime and can’t be aimed at strong light. If you have to test it during the daytime, the front lens cap should never be removed. You can observe the target through the hole in the protection cap.
Use good-quality lithium or alkaline batteries, because bad-quality batteries will affect the performance of the NVD and easily damage the device.
Try to avoid the rain and mist, avoid dropping, shaking and collision. Use a clean soft cloth and dampen in alcohol, if necessary
A useful tip is to remove the battery when the night vision will be not in use for over 3 days to prevent battery leakage and damage the device.
NOTE!
It is normal that the device can not be turned on when the ambient light
exceeds 40 Lx. This device has a protection system, which turns off the image
intensifier when the ambient light level exceeds the limit of 40 Lx during a
10-second period.
Failure to follow the above precautions may cause the device damage and will void the manufacturer’s warranty.
Troubleshooting
The device does not turn on
- Reinstall the battery with the correct polarity.
- Replace battery.
- Clean the battery compartment, focusing on the contact points.
The observed image flickers or flashes
- This means there is too much light (e.g. obervation during twilight conditions).
- Turn off the device or place the objective lens cover.
- The device will function normally in light conditions, not in excess of 0.1Lx (full moon).
The image is missing or not focused
- Re-focus the device by adjusting the objective lens. Adjust the diopter setting by rotating the eyepiece, if necessary.
- Check the cleanliness of the objective surface and eyepiece and clean if necessary.
- Replace batteries.
- In extreme low light conditions, activate the built-in IR illuminator.
The image disappeared or its quality worsened
- Automatic shut-off might occur to protect the device from excessive light. Attach the objective lens cover and ensure that the device starts to function normally. Turn the device off and wait until the conditions darken to continue observation.
- Bright light sources (e.g. street lights) may cause visibility to decrease or disappear. Turn the monocular away from the light source, visibility will restore itself in several minutes.
You see black dots on the screen
- These dots are minor cosmetic blemishes resulting from the image intensifier production processes and are not a sign of a defective or low-quality device.
- These dots do not interfere with the reliability and performance of the monocular.
