1.Up and down:
Unlocking the height locking knob of helmet mount counterclockwise. Slide the knob up and down, adjust the eyepiece to the most suitable height to observe. Clockwise rotates the height locking knob of the helmet mount to lock the height. The red diagram is shown in Fig.
2.left and right:
press the left and right adjusting button of the Helmet Pendant with your finger to slide the night vision instrument assembly horizontally. When it is adjusted to the most suitable position, loosen the left and right adjusting button of the helmet pendant. The night vision assembly will lock this position and complete the left and right horizontal adjustment. As shown in Fig.
3.Front and aft:
when the distance between the eyepiece and the human eye needs to be adjusted, First turn the equipment locking knob on the Helmet Pendant counterclockwise. Then slide the night vision module back and forth and adjust it to the right position. Clockwise rotation of equipment locking knob, locking device, before and after adjustment. As shown in Fig. blue.
