It is important to remember that many factors can affect the accuracy of your scopes zero
including ammo type, temperature, humidity, elevation, distance, angle, and other conditions.
Changing ammunition brands can affect accuracy as well.
Illuminated Reticle
There is a raised dot on the Rubber Armor as an Indicator
Mark on the Ocular Bell Housing, for the Illuminated Reticle
settings.
Depending in which direction you turn the rheostat, the
reticle can be illuminated in Red or Blue with multiple brightness
levels for each color. If you look closely at the top of the knob
you will notice a series of numbers. “0” represents the OFF
positions. If you turn the knob in either direction the reticle will
be illuminate in Red or Blue. There is 5 brightness levels, “1”
being the dimmest and “5” being the brightest for each of the colors.
Adjust the brightness level as needed in accordance with the surrounding conditions. The illumination
will increase reticle visibility especially during dusk and dawn. When the illumination is turned OFF the reticle
will appear as the normal Black Reticle. Be sure the Rheostat Knob is set to the “0” position when not in use
to preserve battery life.
Battery Installation
The Octagon Scopes have a CR2032 type battery in the rheostat.
1. The Battery compartment is located within the Rheostat Knob.
2. On the top of the Rheostat Knob you will notice a thin cap. To
remove this cap grasp it firmly with one hand and twist it counter-
clockwise while holding the rheostat knob firmly in place with the
other hand.
3. Remove the old battery and dispose of it properly. Replace it with
a new 3 volt Lithium Battery type CR2032 only. Place the
Battery in the Battery compartment with the Positive “+” terminal
facing out. Twist the Battery cap back on to the Rheostat Knob
and hand tighten. Avoid using tools (such as pliers) to perform
this procedure as this may cause damage to the unit.
