The maintenance should be carried out at least twice a year and includes the following steps:

  • Wipe the exterior surfaces of metal and plastic parts off dust and dirt with a cotton cloth. To avoid damage to the paint coating, do not use chemically active substances, solvents, etc.
  • Clean the electric contacts of the battery pack and battery slots on the riflescope using a non-greasy organic solvent.
  • Check the lenses of the eyepiece, objective, and rangefinder. If necessary, remove dust and sand from the optics (it is preferable to use a non-contact method). Cleaning of the exterior surfaces of the optics should be done with cleaners designed especially for this purpose.


The device does not turn on
Possible cause: The Battery Pack is empty.
Solution: Charge the Battery Pack.

The device does not operate from an external power source
Possible cause: USB cable is damaged.
Solution: Replace USB cable.
Possible cause: The external power supply is discharged.
Solution: Charge the external power supply.

The image is fuzzy. There are distortions in the form of bars of different widths lying in different directions, or dots of different size and brightness.
Possible cause: Calibration is required.
Solution: Perform image calibration according to Calibration Mode section.

Black screen after calibration
Solution: If the image does not clear after calibration, you need to recalibrate.

The reticle is blurred and cannot be focused with the dioptre ring
Possible cause: The dioptre adjustment range is not enough for your eyesight.
Solution: If you wear glasses with a range of -3/+5, keep glasses on when looking through the eyepiece.

Coloured lines appeared on display or image has disappeared
Possible cause: The device was exposed to static electricity during operation.
Solution: After exposure to static electricity, the device may either reboot automatically, or require turning off and on again.

The image is too dark
Possible cause: Brightness or contrast level is too low.
Solution: Adjust the brightness or contrast in the Quick Menu.

The reticle is crisp but an object at least 30m away is blurry
Possible cause: Dust and condensation are covering the outside or inside optical surfaces.
Solution: Wipe the outer surface of the objective lens with a soft cotton cloth. Dry the riflescope. Let it stand for four hours in a warm room.
Possible cause: The lens is not focused.
Solution: Adjust the image sharpness by rotating the lens focus ring.

The point of impact shifts after firing rounds
Possible cause: The riflescope is not mounted securely or the mount was not fixed with thread sealant.
Solution: Check that the riflescope has been securely mounted. Make sure that the same cartridge type and load bullets are being used as when the scope was initially zeroed. If your riflescope was zeroed during the summer, and is now being used in the winter (or the other way round), in the day or night, or through extreme temperature changes) slight shifts in points of impact are possible. Double-checking your zero before hunting is recommended.

The riflescope will not focus
Possible cause: Wrong settings.
Solution: Adjust the riflescope according to the Powering on and Image Setting section. Check the outer surfaces of the objective lenses and eyepiece and, where necessary, wipe away dust, condensation, frost, etc. In cold weather, you can use special anti-fogging coatings (e.g., the same as for corrective glasses).

Smartphone or tablet cannot be connected to the device
Possible cause: Password in the riflescope was changed.
Solution: Delete network and connect again inserting the password saved in the riflescope.
Possible cause: There are too many Wi-Fi networks in the area where the riflescope is located which may cause signal interference.
Solution: To ensure stable Wi-Fi performance, move the riflescope to an area with few or no Wi-Fi networks.
Possible cause: The device has a 5 GHz network enabled, but the smartphone only supports 2.4 GHz.
Solution: Switch the device’s WiFi bandwidth to 2.4 GHz. More information on solving problems with connection to Stream Vision 2 by following the link.

Wi-Fi signal is missing or interrupted
Possible cause: Smartphone or tablet is out of range of a strong Wi-Fi signal. There are obstacles between the device and the smartphone or tablet (e.g., concrete walls).
Solution: Relocate smartphone or tablet into the Wi-Fi signal line of sight. More information on solving problems with connection to Stream Vision 2 by following the link.

The image of the object being observed is missing
Possible cause: Observation through glass.
Solution: Remove the glass from the field of vision.

Poor image quality / Reduced detection distance
Possible cause: These problems may occur during observation in adverse weather conditions (snow, rain, fog etc.).

There are several light or black dots (pixels) on riflescope’s display or microbolometer
Solution: The presence of dots is caused by peculiarities of microbolometer or display production technology and is not a defect.

When the device is used in low temperature conditions the image quality is worse than in positive temperatures.
Possible cause: In positive temperature conditions, objects being observed (surroundings and background) heat up differently because of thermal conductivity, thereby generating a high temperature contrast. Consequently, the image quality produced by the thermal imager will be better. In low-temperature conditions, objects being observed (background) will cool down to roughly the same temperature, which leads to a greatly reduced temperature contrast and a degraded image quality. This is
normal for all thermal imaging devices.
