Illuminated Reticle
The MARK III Series Scope is equipped with a Reticle that can be illuminated in green for use when
exterior lighting conditions are less than optimal. Control of the illumination is achieved by simply
rotating the Rheostat Knob [C] in one direction or the other.
If you look closely at the side of the Rheostat Knob [C] you will notice a series
of numbers. “0” represents the Off position. If you turn the knob in either
direction the reticle will illuminate green. The illumination reticle can be set to
7 levels of intensity, “1” being the dimmest and “7” being the brightest.
Adjust the brightness level as needed in accordance with the surrounding
conditions. The illumination will increase reticle visibility, especially during
dawn and dusk. This illuminated scope is not intended for use in total
darkness. When the illumination is turned off the reticle will appear as
normal, with Black reticle lines. Be sure that the Rheostat Knob is set to the
“0” position when not in use to preserve battery life.
Care and Maintenance
Your NcSTAR MARK III Series Scope is shock proof, fog proof, and water proof. However, you
should never try to take the scope apart or clean it internally. The exposed optical lens surfaces will
perform their best if they are routinely cleaned with a lens brush or a lens cloth. For a deep cleaning,
you can also use high grade camera lens paper and camera lens cleaning solutions. Never use any
other type of materials or solvents other than those designed specifically for optical lenses to avoid
damaging your scope. Clean the outer portion of the lens cavity first with cotton swabs, clearing as
much debris and dust as possible. Then, gently clean the lenses using a circular motion starting in
the center and ending at the edges. Do not rub the lenses continually; simply wipe in short circular
patterns. Maintain the exterior surfaces of the scope by removing dirt or sand by using a soft brush
or a soft dry cloth. You can also use a silicone treated cloth to restore luster and protect the exterior
of the scope against corrosion. Be careful not to touch any of the lenses with the silicone cloth. It is
not necessary to lubricate any part of the scope as all of the moving parts, such as the turrets and
the fast focus eyepiece, are permanently lubricated. When not in use, always store your scope in a
cool dry place with the lens caps on to prevent scratches to the lenses.

seek the help of a qualified professional to avoid damage to your scope
and your firearm.
