APPLICATION
The Aries 258 night vision weapon scope is a complex computerized system for the observa-
tion of objects at low light levels (less than 1.0 lux. ) Containing an on board computer, these
scopes are some of the most advanced night vision weapon scopes in the world
The Aries 258 consists of the objective lens assembly, ocular lens assembly and the body.
The body contains the image intensifier tube assembly with the integrated high voltage power
source. The body also houses the electronics for the reticle, the computer console for the
“Smart Technology” as well as the battery compartment. The 100M infra-red illuminator is
located on the opposite side from the battery compartment.
The objective lens protective cover is designed to protect the lens from scratches and abra-
sions. This cover also protects the image intensifier tube from exposure to daylight or other
bright light sources. The protective cover acts as a daylight filter, note the pinhole in the center
of the lens cap.
NOTE:
Please refrain from testing in the daylight for more than ten (10) minutes at a time.
MASTER POWER SWITCH
The master on/off switch is to be found on the back of the unit. Once the scope’s master
power switch is turned to the “ON” position, you will then be able to adjust the scope from the
control box.
CONTROL PANEL
The Cluster of three buttons on the side of the Aries 258 are your controls for the unit. The
“SL” button acts as a three way
selection
toggle. By pressing it once, you will see one of three
colored diodes, located on the rear side of the control box, light up. Make sure to keep both
eyes open, and we suggest that you use your right eye for aiming through the scope. This will
give you a HUD (Heads Up Display) of the scope’s functions while using the scope. The + and
- adjustment buttons increase and decrease the level of a particular function.
The three colored
led diodes
represent the mode of function of the scope. “
B
” for
B
rightness
of the light intensifier tube, “
R
” for
R
eticle brightness, and “
I
” for
I
R Illuminator brightness.
LIGHT INTENSIFIER TUBE BRIGHTNESS ADJUSTMENT
The
green diode
“
B
” represents light intensifier tube power ratio. Once this is lit you can
adjust the brightness of the light intensifier with the “+” and “–” adjustment buttons.
NOTE:
The Aries 258 is a GEN 1 Night Vision device, adjustments Involving the light intensifier
tube will be subtle due to the nature of the design. Adjusting the tube’s power down will take
longer to take effect than adjusting it up. You may notice a persistent green glow after the unit
has been turned “OFF”(don’t keep pressing the key) this too is due to the nature of the design of
a GEN 1 light intensifier tube’s power supply.
RETICLE BRIGHTNESS ADJUSTMENT
By pressing the “SL” button again you will see a
yellow diode
“
R
” light up next to the green
one. The
yellow diode
represents the reticle’s brightness. Adjustments should be easily seen
if you look through the Aries 258 while you work the “+” and “–” adjustment buttons.
To adust the brightness of the reticle, or to turn It off all together, use the buttons located on the
control box on the side of the unit press and hold one of the “+” or “–” adjustment buttons while
the yellow diode is lit and looking through the scope to see the change in brightness. When
desired brightness is reached, release the button.
