NVS 6
MANUAL
7 OPERATION PROCEDURE
7.1The conditions in which the night-vision goggles are operated have their own idiosyncrasy, which requires certain skills on the part of the pilot as the image of the terrain and objects visible through the night- vision goggles is monochromic and not very soft.
7.2The night-vision goggles enable the pilot not only to nap off the earth but also view the instrument panel by taking a look downwards or sideways past the eyepieces.
CAUTION: WHEN THE NVS 6 IS USED AT NIGHT TIME, THE SAFETY CAPS SHALL BE REMOVED FROM THE LENSES.
7.3For removing the safety caps, press simultaneously on both retainers and, while holding them depressed, take the cap off of the lens mount. Put the removed caps into the case pocket.
7.4After removing the safety caps, focus the lenses of each monocular by rotating the lens about its optical axis so as to attain the sharp image of the viewed objects in the space outside the cockpit (for convenience of rotation each lens is provided with knurling).
7.5In case that the airborne power supply is not available, turn on the independent power source to feed power to the night-vision goggles by turning cap (6) of cap-switch (5) (Ref. Fig. 6.4).
7.6If the night-vision goggles become exposed to bright light, turn your head to divert the lenses sideways so as to bring the image of bright light sources outside the field of view.
7.7In the event of fogging of the eyepieces of the night-vision goggles (low temperature), pull the goggles out of the operating position and wipe dry the external surfaces of the eyepieces with a cloth included in the single set of spare parts.
7.8After long usage of the night-vision goggles on the pilot’s head (more than 2.5 h), the pilot may feel a light fatigue in the neck muscles.
