CARE AND MAINTENANCE
Your
DRGB135 is a sealed unit, please do not attempt to take it apart or clean it internally. The
exposed optical lens surfaces will perform their best if they are routinely cleaned with a lens brush
and the lens cloth provided with your sight. For a deep cleaning, you can also use high quality
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 sight. 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 of the optics body and protect the scope against
corrosion. Be careful not to touch any of the lenses with the silicone cloth. When not in use, always
store your sight in a dry place with lens covers on to prevent scratches to the lenses.
If you are not sure about any of the procedures in this manual, always
seek the help of a qualified professional to avoid damage to your optic
and your firearm.
