6.3.8 Fasten cable (14) on counterweight (9) using strap (10) (Ref.
Fig. 6.5, Step 6.2.15).
6.3.9 With the goggles placed in the stowed position secure helmet
soundly on the pilot’s head.
6.3.10 Connect cable (14) to cable (20) with the use of the connector
(25) (Ref. Fig. 6.7).
6.3.11 Turn on the switch to apply the helicopter electrical power to
the night-vision goggles.
6.3.12 Depress 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.
