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.

5.1Manual 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.
