IMPORTANТ!
Make sure to carefully read the present manual before using the device to ensure its safe exploitation.
Thoroughly test the device before use after it has been left in storage for a long period of time.
Disassembling the device is prohibited, except in authorized repair centers.
The external optical surfaces should be clean at all times. Touching the optical surfaces with bare hands is not recommended.
Sand and sea water can damage the optical coatings!
Do not point the device directly at the sun!
Image performance (quality) depends on the scenery and the atmosphere conditions. The contrast of the image may vary as a function  ofthe  timeof day due to the effect
of the sun. For example, at  sunset objects will have absorbed different levels of heat resulting in greater temperature differences and better contrast.
When storing the device for a longer period of time, the battery has to be removed and stored in polyethylene bags to prevent contact with metal. It is recommended to recharge the battery every two to three months.
Condensation can cause fogging of the external optical surfaces! Condensation occurs when:

• Moving the device from cold to warm place or vice versa;
• The device’s temperature differs significantly from the ambient one;
• Using the device in places with high humidity.

When the temperature of the device is equalized with the ambient one, the condensation disappears. Use the cleaning cloth to remove moisture. Condensation also can be prevented with anti-fogging sprays or with the provided rubber pieces. Condensation on the objective does not affect the performance of the device!
Clean the lens surfaces with the Lens Pen®.

PRODUCT OVERVIEW

Viper 50 Next multi functional thermal imaging device is purposefully designed for installation in front of daytime rifle scopes or other observation devices as well as a standalone hand held device, ensuring clear view in variety of environmental conditions, including fog, rain, snow, smoke, total darkness. The sophisticated ultra lightweight and low-profile design of the Viper 50 Next multi functional thermal imaging device eliminates the need to remove the day sighting equipment since the Viper 50 Next mounts easily directly in line with a standard daytime rifle scopes without the need of tools. Such a combination allows the user to avoid re-zeroing the rifle every time the sight setup is changed since the primary sight remains undisturbed. The point of impact remains the same no matter how often or how many times the clip-on is mounted. Viper 50 Next is based on the A-CORE module with proven 320×240 pixels detector resolution and ultra small 12 μm pitch size. The housing is made of durable and extremely resistant magnesium alloy and is coated with matte anti-reflective coating.

When using the device in low lighting conditions and for an extended period of time, consider lowering the brightness levels to extend the battery life and to avoid eye fatigue.
A single short press of the button shows the current Luminance value. Pressing the button again in close succession will cycle through the available luminance values. The value of the manual luminance option can be configured through the user menu. Press and hold the button for more than 2 seconds to invert the image, i.e. warm object appear in black hot or in white hot and vice-versa. The change of polarity is denoted by the BH or WH symbols that appear on the screen for 2 seconds.

MENU

5.1 Navigation
ATTENTION!
The buttons and are dual purpose buttons!

Besides the main and secondary functions, they also serve for entering and navigation through the menu.

5.2 Appearance

ATTENTION!
When the Menu is activated and the user is inactive for more than 20 seconds, the Menu is automatically deactivated.
The function is not active in the Alignment and Manual Bad Pixel Replacement (MBPR) sub-menus.

NOTE
To quickly exit the device Menu function, hold down the (Brightness) button for more than 3 seconds.

5.2.1 .1 Brightness
5.2.1 Image

Selecting Brightness gives the opportunity to set your own user-defined level of image brightness.
Brightness is not related with the Luminance adjustment performed by the button !

5.2.1 .2 Contrast
Selecting Contrast gives the opportunity to set your own user-defined level of image contrast (Gain).
Increasing the contrast value will ensure better object contrasting and easier detection. However this will decrease the details on the observed object. Decreasing the contrast value will make the details visible.

5.2.1 .3 Palettes
A variety of color palettes can be used:
White Hot, Black Hot, Red Hot, Iso­ therm, Auto Isotherm, Rainbow and Ironbow.

| White Hot
---|---
| Black Hot
| Red Hot
| Iso therm
| Auto Iso therm
| Rainbow
| Ironbow

The pictogram in the main menu shows the active user selection.

White Hot and Black Hot – Choosing Black Hot (warmer objects appear in black) and White Hot (warmer objects appear in white) is up to user’s personal preference.
Red Hot – recommended mode for prolonged observation. The image is red black to minimize the blue light emitting from the display and is more comfortable on the eyes.
Isotherm – the objects above the threshold temperature are colored in different shades of red.
The temperature threshold can be set (increase/decrease) by the temperature scale shown.

Increasing the threshold value ignores the colorization of the colder objects.
This option is highly dependent from the distance to the object. It is highly recommended to try different values of the threshold in the daily usage to find the right value for
your personal preference.

Auto Isotherm – the AUTO Isotherm mode enables a marked object to be set as the lowest temperature object in the scene, and the other objects in the scene with higher temperatures are highlighted with yellow-red colors with graduation to this temperature threshold automatically.

When activating the function (with long press of the button) a marker appears on the center of the screen and pictogram notifying the current mode. The pixels around the marker are taken as a minimum threshold temperature value. Setting the value (marking the object) is performed by short pressing the Brightness button. To deactivate the mode long press the brightness button to enter WH/BH mode and the pictogram disappears. The activation and deactivation of this feature should be available also
from the menu.

Rainbow and Ironbow – The palettes Rainbow and Ironow help increase chances for recognition & identification of the objects.

5.2.1 .4 Scene Type
Two types of auto contrasting, for better performance:

**** Highlights – this type of image contrasting is suitable for detection and observation.
Panorama – The picture is very stable during changes in the dynamics of the scene. Suitable for observing panoramic  scenes with combination of: forest and sky, earth and sky, scenes on the horizon, etc.
The pictogram Scene Type in the main menu shows the active user selection.

5.2.1 .5 Weather Type
The image quality is strongly depending on weather conditions. When the weather is wet (fog, rain,etc.) the dynamic range of the scene is reduced, causing the contrast of the
image to lower. To prevent this effect, this option provides a filter, that enhances the details of the low contrast image in wet weather conditions (incl. fog and haze). You may choose between 3 filters:

|   Hot Weather
---|---
|   Normal Weather
|   Wet Weather

Wet and foggy weather conditions with Normal Weather Type Filter
Wet and foggy weather conditions with Wet Weather Type Filter

NOTE
During good weather conditions please select (normal weather). Otherwise the image will be noisy.
5.2.1 .6 Filter
For a more detailed image and clear edges, you can switch between 3 levels of image sharpness:

|   Smooth
---|---
|   Normal
|   Sharp

The pictogram in the main menu shows the active user selection.

• Manual mode – The calibration is performed by the user, by pressing and holding the button for more than 2 seconds, at desired intervals, with a shutter mechanism located in the device. It is not necessary for the user to cover the lens with an external barrier.
• External mode – The calibration is performed by the user, by pressing the button, at desired intervals, with an external lens barrier, which can be a hand or the protective cap of the lens. The user must eliminate the entry of energy through the lens to the sensor of the device. Calibration without closing the lens will create a “ghost” effect in the image.

IMPORTANT!
In manual and external calibration mode (NUC), the pictogram for the respective is permanently displayed.
When the user switches to Auto NUC from some other calibration mode, the icon appears on the display for 5 seconds and then disappears.

5.2.3.2 Alignment

With Alignment function, you can precisely align the optical axis of the day sight and the clip-on attachment. The manufacturing process of the device ensures the shooting precision tolerance up to 5 cm at 100 m. By this Alignment function, you can achieve much better accuracy.
Entering the Alignment function allows shifting the image in all directions to align it to the day scope zero, The X and Y values showing the current position of the image and If the impact point is different than the center point of the day scope, the image should be moved in a direction opposite of the impact point by changing the X and Y values (up/down or left/right).

The action is performed with the (up/right) and (down/left) buttons.
Switching between directions is performed by short pressing the button.

Move the image so that the point of impact matches with the center point of the day scope. Example: If the impact point is right below the impact point of the day scope, the
image should be moved up and left.

ATTACHMENT

7.1 Installation in front of the daytime rifle scope

NOTE!
During shooting with the clip-on thermal device Viper 50 Next attached to the daytime rifle scope with help of the fixed adapter. The adapter could move along the daytime rifle scope. The size of this movement depends on the tightening force of the locking thumb and recoil force of the weapon and could be equal to 1 mm on each shot. This movement is allowed and does not affect the impact point. The position of the adapter should be controlled after each shot in the shooting sequence.

NOTE
Always check and make sure that the counter ring providing with the Viper 50 Next device is tightened to the adapter securely and ensures the thread and the connection adapter-device firmly enough.

** TIp
Mark both – the clip-on and the daytime rifle scope and check markers for displacement   fter each shot.
WARNING!**
Use of this device may be restricted by national regulations. You should consult with local authorities prior to using the clip-on thermal device Viper 50 Next.

NOTE
Images used in the following instructions are for illustrative purposes only. Diameter and the appearance of the counter ring may vary due to the diameter of the used daytime  ifle scope and the manufacturer of the counter ring.

11.1 Product description

The Viper 50 Next device allows detection of objects that emit energy in the infrared spectrum. The equipment can operate in rain, fog and total darkness in a completely passive mode (without additional illumination). The active matrix is microbolometer, working in the wavelength range from 7 to 14 μm. The unique design of the device makes it reliable and ergonomic.
The body is made of strong, ultra-lightweight magnesium alloy and has been applied with matt anti-reflective coating. The device’s functions can be accessed through the buttons, while the OSD (on-screen-display) provides status information about it’s current condition.

11.2 Principle of operation

Thermal cameras detect temperature by recognizing and capturing different levels of infrared light. This light is invisible to the naked eye, but can be felt as heat if the intensity is high enough.
All objects emit some kind of infrared radiation, and it’s one of the ways that heat is transferred. If you hold your hand over some hot coals on the grill, those coals are emitting a ton of infrared radiation, and the heat is transferring  to your hand. Furthermore, only about half of the sun’s energy is given off as visible light—the rest is a mix of ultraviolet and infrared light.
The hotter an object is, the more infrared radiation it produces. Thermal cameras can see this radiation and convert it to an image that our eyes can see.
A special germanium objective lens focuses the infrared energy emitted by all of the objects in field of view of the device. The focused radiation is scanned by an array of infrared-detector elements. The detector elements create a detailed temperature pattern of the observed scene called a thermogram. The signal generated by the detector elements is passed through an analog-to-digital converter and translated into discrete electric impulses. The impulses are sent to an image-processing unit, a circuit board with a dedicated chip that improves the image quality and converts the information from the elements into data for the display. The signal-processing unit sends the information to the display, where it is displayed as a different shade of gray depending on the intensity of the infrared emission. The combination of the impulses from all of the detector’s elements creates the final image.
