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.).

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.
