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.
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.
