NVS 6
MANUAL
6.2.13Carry out preparatory operations on the pilot’s helmet in compliance with the Manual. Loosen cross-shaped knob (11) and use it to move visor guard (15) fully so that the visor guard is retracted under the casing. These done, fix the visor guard in this position by tightening the cross-shaped knob.
6.2.14Install the night-vision goggles, which are currently placed in the stowed position, onto the helmet (with the helmet removed from the head), by joining the fixing assembly of the night-vision goggles to the helmet mount. To do so, insert the plate of the fixing assembly of the night-vision goggles into the slots of guide (12) (Ref. Fig. 6.4) of helmet mount (26). Exercise due care to avoid misalignment, then, turn the plate upwards until retainers (13) become latched.
6.2.15Attach cable (14) to the helmet by first passing it under unfastened strap (10) on counterweight (9) and then fasten the strap using the sticking fastener.
6.2.16Secure the helmet, complete with the goggles placed in the stowed position, on the pilot’s head.
6.2.17Transfer the goggles to the operating position (Ref. Step 6.2.2 of this Manual) and turn them on (Ref. Step 6.2.7 of this Manual).
6.2.18Set RH side monocular (29) precisely opposite the right eye of the pilot. To do so, ease up knob (2) and displace the monocular pair of the night-vision goggles in the cruciform guides of the fixing assembly upward or downward, forward or backward. Simultaneously turn them about the axis of knob (2) to find the optimum position at which the NVS 6 monocular pair is properly set away from the eyes and their optical axes have the required tilt.
By an optimum position of the monocular pair relative to the pilot’s eyes, is meant, a position that provides adequate conditions for carrying out observation of the full field of view of the RH side monocular with the
