Switching the Unit off
After you have finished using the Unit, turn it off by rotating the
On/Off/IR/Auto switch to the ‘OFF’ position. Replace the
objective lens cap. If storing the unit for an extended period,
remove batteries. Place Unit in appropriate storage container.
Adjusting to individual vision
Turn on the Unit. Direct the Unit at an object placed within 8-15
m from the viewer. While looking through the Unit at the object,
first rotate the diopter adjustment ring on the eyepiece (4, Fig. 1).
Once focus is nearly achieved, rotate the objective lens (3, Fig. 1)
to achieve final focus.

Manual gain adjustment
Each NVS 14 series device is equipped with a manual gain
adjustment system (9, Fig. 1). This system allows the user to
adjust the gain (or light amplification) of the Unit in accordance
with the prevailing light conditions.
The manual gain system allows for the gain of the Unit to be set
between 20% and 100%. In relatively dark situations, the gain
should be set high enough that the user can see a clear, well-lit
image in the eyepiece. In relatively bright conditions, the gain
should be reduced to avoid an overly brightened image from
being displayed in the eyepiece.
