4. Continue with this process until you have achieved your desired level of accuracy.
5. Your scope is now Zeroed to your firearm at the distance that you have chosen.
6. Don’t forget to reinstall the Turret Caps over the Turret Dials after your done zeroing. You do
not want to lose/leave behind the Turret Caps at the shooting range.
It is important to remember that many factors can affect the accuracy of your scopes zero including
temperature, humidity, elevation, distance, angle, and other conditions. Changing ammunition
brands can affect accuracy as well.
Battery Installation
Your Euro Series Scope comes with a battery pre-installed from the factory. To replace the battery
follow these simple steps:
1. The Battery Compartment is located within the Rheostat Knob on top of the
Ocular Lens Housing.
2. On 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 your other hand.
3. Remove the old battery, and dispose of it properly. Replace it with a new 3 volt
Lithium Battery Type CR2032 only. Twist the battery cap back on the Rheostat
Knob and hand tighten. Avoid using tools (such as pliers) to perform this
procedure as this may cause damage to the Illumination System.
Illuminated Reticle
Euro Series Scopes equipped with an Illuminated Reticle, can be illuminated in red 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 red. The illumination reticle can be set to 11 levels of intensity,
“1” being the dimmest and “11” 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.
