CAREFULLY READ THE INSTRUCTIONS BEFORE
USE!
MISUSE WILL VOID THE WARRANTY.
1. BRIEF DESCRIPTION
DN482/483 Night Vision Scope is a modern, universal night vision
device designed for a wide range of activities from amateur to
professional needs:
• Nighttime observation and hunting
• Law enforcement and security
• Search and rescue
• Wildlife observation
• Nighttime photography and video
The device is equipped with a Second or Third Generation high-
quality electro-optical image intensifier (Gen. II+/III, 18 mm MCP)
utilizing the principle of multiple intensification of the image
brightness in the visible and IR spectrum which guarantees an up to
400 – 700 m observation range.
NOTE.
Detection and recognition range provided by the device depends on
the type of the objective lens used and the observation conditions:
light available, transparency of the atmosphere and target quality.
The identification range increases in the conditions of high light, at
moon night, if the target is situated on a light background (sand,
snow). The identification range decreases in the conditions of low
light, low transparency of the atmosphere, if the target is situated
on a dark background (plough-land, stems of trees, etc.).

9. STORAGE AND MAINTENANCE INSTRUCTIONS.
Warning!
After transportation or keeping the device at temperature lower
than -40
°C (-40°F), the device must be warmed up to ambient
temperature, from -10 °C (14°F) to +40°C (104°F), relative
humidity of 80% max. at 20 °C (68°F).
Precautions
DN482/483 is a sophisticated precision optical instrument equipped
with electronics.
Therefore, it should be handled with due care.
• Keep your device away from direct sunlight, impacts, dust,
moisture, and sudden changes of temperatures.
• Do not keep the device at temperatures higher than 60 o C
(140 o F).
• Do not touch the optical surfaces with fingers. Doing so may
damage the anti-reflection coating.
• Cleaning of optical surfaces is only allowed with professional
camera lens cleaning supplies.
• To clean the exterior of the device, use a soft clean cloth.
• Do not take the cover off the lens if not necessary.
• Keep away from heating appliances and central heating.
• Make sure to switch off the unit during periods of non-
operation and when storing the device for long period of time.
• Do not apply superfluous efforts at work with lens assembly,
agile elements and thread connections.
• Due to considerable optical magnification of the eyepiece some
small structures inside the tube coating in the form of dark
and/or white points may be seen in the field of view, which
does not affect the serviceability of the device.
