Features

  • This night vision device features an integrated infrared illuminator. The brightness is adjustable by pressing the appropriate buttons (4, 5).
  • The brightness of the image display can also be adjusted by pressing the appropriate buttons (4, 5).
  • The device magnifies residual light to create an image when the infrared illuminator is switched off. Observations in total darkness are possible when the infrared illuminator is switched on.
  • Operating time with these batteries is about 6 hours when the infrared illuminator is switched off. With the infrared illuminator turned on, operating time is reduced to about 4 hours.
  • In low light conditions, the maximum range of finding an object for observation is more than 200 metres. In total darkness, with infrared illumination switched on, the range of finding an object is more than 60 metres.
  • When the device is turned on, the memory function will restore the last display brightness and infrared illuminator settings used before it was turned off.

Operation

Line up the device with an object that is 20-30 metres away. Look through the eyepiece (3) and turn it until the black frame of the screen is clearly visible. Adjust the focus to ensure a clear image of the object by turning the objective lens (2). When adjusting the observation distance, you will achieve a higher quality image simply by turning the objective lens (2). No further turning of the eyepiece (3) is required, your device is now set-up and ready to use.
