2 IF THE POWER SUPPLY OF THE GOGGLES FROM THE
HELICOPTER ELECTRICAL SYSTEM IS NOT AVAILABLE, THEIR
OPERATION MAY BE PROVIDED FROM THE INDEPENDENT BUILT-IN
POWER SOURCE (TWO BATTERIES AA R6 1.5 V OR
RECHARGEABLE BATTERIES OF A SIMILAR TYPE).
6.3.13 If the alignment of the monoculars of the night-vision
goggles with respect to the eyes of the pilot is not accurate enough and
the monocular pair is not adjusted to suit individual features of his
eyesight, perform the adjustment operations as prescribed by Steps 6.2.19,
6.2.20 of this Manual.
Now the goggles are ready for work.
Upon completion of work with the goggles, carry out the following
operations:
6.3.14 Take hold of the monocular pair with one hand and the fixing
assembly with the other hand and transfer the night-vision goggles to the
stowed position (i.e. "fold up" the fixing assembly by overcoming the force of
the retainer which locks the goggles in the operating position).
6.3.15 Turn off the switch used for supplying power from the
helicopter electrical system to the night-vision goggles.
6.3.16 Disconnect cable (14) (Ref. Fig. 6.7) from cable (20) by
disengaging the connector (25).
6.3.17 Take off the helmet complete with the night-vision goggles
installed and detach the counterweight from the helmet.
6.3.18 Remove the night-vision goggles from the helmet by pulling
them down by hand, having pressed levers (18) (Ref. Fig. 6.4) to disengage
the goggles fixing assembly plate from the guides of mount (26) of the helmet.
6.3.19 Remove screws (27) and remove mount (26) from the helmet.
