ATN MK 8750, MK 7750 Light Intensifier Tube Brightness Adjustment, Reticle Brightness Adjustment

LIGHT INTENSIFIER TUBE BRIGHTNESS ADJUSTMENT

The green led “B” represents the light intensifier tube power ratio. Once this is lit you can adjust the brightness of the light intensifier with the “+” and “-” adjustment buttons.

Green LED “B”

RETICLE BRIGHTNESS ADJUSTMENT

Yellow LED “R”

By pressing the SL button twice you switch to a yellow “R” diode next to the green one. The yellow diode represents the reticle’s brightness. Adjustments could be easily seen if you look through the Aries MK6600/6650/7700/7750/8700/8750 while pressing “ +” /” -” adjustment buttons.

To adjust the brightness of the reticle or to turn it off use the con- trol box buttons located on the side of the unit. Press and hold “+ “or” -” adjustment buttons while the yellow diode is on and see brightness changes looking through the scope. After appropriate level of brightness has been set release the button.

INFRA-RED ILLUMINATION

By pressing “SL” button three times you can switch to Red diode “I”. Red diode represents 100M infra-red illuminator’s bright- ness adjustment mode. Adjustments can be easily observed through the Aries scope while pressing” +” /” -” adjustment but- tons.

Infra-red illuminators, or IR illuminators, are common to night vision. The IR light greatly enhances to the performance of the Aries MK6600/6650/7700/7750/8700/8750 while remaining almost totally invisible to the unaided eye.

Power up the Aries scope in a dark environment. Find an object and examine it with IR off, then on. You could observe illumina- tion difference. It is important to remember that the IR illuminator is simply an infra-red light source and like any light source it may loose its effectiveness over long distances.

To change the field of coverage from the IR illuminator, focus the beam by turning IR illuminator lens to slightly alter the beam width.
