ATN Night Vision Biocular manual INFRA-RED Illuminator, LOW Battery Indicator, Focusing

INFRA-RED ILLUMINATOR

The infra-red illuminators, or IR illuminators, are common to night vision. The IR light greatly enhances the performance of the Night Shadow while remaining almost totally invisible to the naked eye. The IR illuminator on the Night Shadow is

located on the side of the unit.

To turn the IR on push the IR button and you will see the orange indicator light come on. It is important to remem- ber that the IR illuminator is simply an infra-red light source, and like any light source it may loose its effective- ness over a great distance.

Remember: If you twist and pull the IR you will increase the distance while decreasing the angle and vice versa.

NOTE: The IR will automatically turn off when the unit’s main power is turned off.

LOW BATTERY INDICATOR

The low battery indicator is another feature that is programmed into your “Smart” bioculars. If the batteries start losing voltage the ON/OFF LED starts to pulse and it is time to replace your batteries.

FOCUSING

NOTE: The distance between your eyes could be adjusted by manipulat- ing the biocular eyepiece of the Night Shadow.

To focus the Night Shadow you will need to adjust the diopters first. Simply turn the diopters clockwise until they stop. Then, while looking through the diopters at a subject, slowly turn the diopters back counter- clockwise until the grain in the image is sharp.

NOTE: We suggest that you focus the diopters in the daytime with the daylight filters on.

Next, focus the front lens until the image and the grain are both sharp. When you are in low-light conditions and the daylight filter is off you may

focus the front lens to receive a sharp image, the diopters should not be adjusted.

NOTE: The front lens should be readjusted as you view objects at different distances.
