MANUAL

6.3.8Fasten cable (14) on counterweight (9) using strap (10) (Ref. Fig. 6.5, Step 6.2.15).

6.3.9With the goggles placed in the stowed position secure helmet soundly on the pilot’s head.

6.3.10Connect cable (14) to cable (20) with the use of the connector

(25)(Ref. Fig. 6.7).

6.3.11Turn on the switch to apply the helicopter electrical power to the night-vision goggles.

6.3.12Depress button (1) (Ref. Figs 6.4, 6.5) and, while holding the fixing assembly with one hand and taking hold of the monocular pair with the other hand, transfer the goggles to the operating position so that the fixing assembly becomes straightened. In doing so, see to it that only slight effort is applied for ensuring proper locking (latching) of the monocular pair in the operating position. Only an effort sufficient to cause operation of retainer (21) is necessary. (Ref. Fig. 5.2). The goggles will get energized.

This done, the pilot shall see amber-green illumination free from flashes and twinkling on the screens of both channels of the night-vision goggles, which is indicative of normal operation of the goggles powered from the helicopter electrical system.

Note – When the night-vision goggles are powered from the helicopter electrical system, they are energized and de-energized automatically in response to their transfer from the stowed to the operating position and vice versa irrespective of the position of cap (6) (Ref. Fig. 6.4) of cap-switch (5).

CAUTION: 1 WHEN THE NIGHT-VISION GOGGLES ARE SWITCHED ON IN THE PRESENCE OF LIGHT OR WITH THE WHITE FLOOD LIGHT TURNED ON, MAKE ABSOLUTELY SURE THAT THE SAFETY CAPS ARE FITTED ON THE LENSES TO PREVENT DAMAGE OF THE UNIT.
