FOCUSING
To focus the Aries 258, first you will need to adjust the diopter. Simply turn the diopter clock-
wise until it stops. Then, while looking through the diopter at a subject, slowly turn the diopter
back counter clockwise until the grain in the image is sharp.
NOTE:
We suggest that you focus the diopter during daylight with the filter 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 diopter should
not be adjusted.
NOTE:
The front lens should be readjusted as you view objects at different distances.
CLEANING THE EYEPIECE
You may need to clean the eyepiece and of the unit you have purchased from time to time in
order to guarantee top performance. When you receive your Aries 258 you should check for
dust on the eyepiece of the unit.
Eyepiece is attached to the body of the unit by two small set screws. By loosening the set
screws you can easily slide out the eyepiece section of the unit. If there is resistance when you
slide out the eyepiece stop and make positive that the set screws are sufficiently loosened.
NOTE:
You do not have to remove the set screws completely, they are very small and easy to
misplace.
Now, with a little more effort in the same counter-clockwise direction, you can unscrew the
eyepiece section of the scope.
Once the eyepiece section has been removed from your Aries scope, you may now clean the
dust off the glass surfaces as well as the phosphor screen of the light intensifier tube. When
reinserting the eyepiece into the scope, make sure it is seated completely with the internal
rubber bushings.
CAUTION:
Use only Photographic lens cleaning tissue on these surfaces. Be careful not to
scratch or smudge any of these surfaces. When using compressed air to blow dust away, make
sure to avoid inverting the can while spraying. This may cause frozen propellent to exit the can,
which can result in serious problems of the glass and phosphor screen.
other situations with strong lighting may result in a temporary decrease of the proximity sensor’s
performance.
LOW BATTERY INDICATOR

programmed into your “Smart” scope. If the bat-
teries start losing voltage.
