4.2. Battery Installation for Illumination
The reticle illumination feature requires batteries. Insert the provided batteries into the designated compartment, typically located on the side turret. Ensure correct polarity for proper function.
5. Operating
5.1. Magnification Adjustment
Adjust the magnification from 3x to 12x using the magnification adjustment ring located near the eyepiece. Rotate the ring to your desired power setting. The 3-12x range provides versatility for various shooting distances.

5.3. Windage and Elevation Turrets
The scope features zero lockable and resettable target turrets for windage (horizontal) and elevation (vertical) adjustments. Each click provides 1/4 MOA adjustment for precise targeting.
- To make adjustments, unscrew the turret caps.
- Rotate the turret to achieve the desired adjustment. Each click represents 1/4 MOA.
- To reset zero, pull up the turret, rotate it to the '0' mark, and then push it down to lock.
5.4. Reticle Illumination
The reticle features a 36-color illumination enhancing digital control system. Use the controls to select your preferred color and brightness level for optimal visibility in varying light conditions. This is particularly useful in low-light environments or against challenging backgrounds.
5.5. Diopter Adjustment
Adjust the diopter ring near the eyepiece to achieve a sharp reticle focus for your individual eyesight. This adjustment compensates for differences in vision, ensuring the reticle is crisp and clear.
6. Maintenance
- Cleaning Lenses: Use the provided cleaning cloth to gently wipe lenses. Avoid using harsh chemicals or abrasive materials that could damage the lens coatings.
- Cleaning Exterior: Wipe the exterior of the scope with a soft, damp cloth.
- Storage: Store the scope in a dry, cool place away from direct sunlight and extreme temperatures. Ensure lens caps are on to protect the lenses.
7. Troubleshooting
- Blurry Reticle: Adjust the diopter ring until the reticle appears sharp.
- Unclear Image at Different Distances: Adjust the side wheel parallax to correct for parallax error.
- Reticle Illumination Not Working: Check or replace the batteries. Ensure they are inserted with correct polarity.
