1. The Battery compartment is located within the Rheostat Knob.
2. On the top of the Rheostat Knob you will notice a thin Battery Cap. To remove this Battery Cap grasp
the knurled edge of the Battery Cap firmly with one hand and twist it off 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 new CR2032 Battery in the Battery Compartment with the Positive “ + ”
terminal facing out towards the Battery Cap. Twist the Battery Cap clockwise back onto the Rheostat
Knob and hand tighten. Avoid using tools (such as pliers) to perform this procedure as this may
cause damage to the unit.
CARE AND MAINTENANCE
Your VISM Dot Sight is a factory 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 edge 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 small 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 unfamiliar with any of the procedures in this manual, always seek the help of a qualified
professional to avoid damage to your Dot Sight and your firearm.
