Newcon Optik DN483, DN482 Precautions, Storage and Maintenance Instructions

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.).

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 60oC (140oF).

•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.
