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.

RETICLE BRIGHTNESS ADJUSTMENT

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.

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.
