3. Setup
3.1 Mounting the Riflescope
Ensure the riflescope is securely mounted to your rifle using appropriate rings and bases (not included). The CTL-3420 features integrated EZ mount leveling indicators to facilitate quick and precise alignment during installation. Align these indicators to ensure the reticle is perfectly level with your rifle.
3.2 Diopter Adjustment
Adjust the diopter ring located at the eyepiece to achieve a sharp, clear view of the reticle. Look through the scope at a plain background (like a clear sky or a blank wall) and rotate the diopter ring until the reticle appears crisp and in focus. This adjustment is personal and should be set for your individual eyesight.
3.3 Battery Installation
The CTL-3420 features an illuminated reticle. Install the provided battery into the illumination control knob according to the instructions in the reticle manual. Ensure correct polarity.
4. Operating Instructions
4.1 Magnification Adjustment
The CTL-3420 offers a 4-20x magnification range. Rotate the magnification ring, typically located near the eyepiece, to adjust the power. The First Focal Plane (FFP) reticle scales with magnification, ensuring holdover points remain accurate at any power setting.
4.2 Reticle Illumination
The LR1-MIL reticle is fully illuminated. Use the illumination control knob to turn the illumination on/off and adjust its brightness. There are 11 illumination settings to suit various lighting conditions.
4.3 Windage and Elevation Adjustments
The riflescope features exposed 0.1 MIL tactical turrets for precise adjustments. Each click of the turret moves the point of impact by 0.1 MIL. The turrets are designed for a precise and rugged feel, allowing for confident adjustments. After zeroing, the turrets can be reset to zero for easy reference.
4.4 Side Adjustable Focus (Parallax)
The side parallax adjustment knob allows you to eliminate parallax error and achieve a clear image at various distances. Rotate the knob until the target image appears sharp and the reticle does not shift relative to the target when you move your head slightly.

5. Maintenance
5.1 Cleaning
Use the provided lens cleaning cloth to gently wipe dust and smudges from the lenses. For stubborn dirt, use a lens cleaning solution specifically designed for optics. Avoid using abrasive materials or harsh chemicals, as these can damage the lens coatings. Keep the exterior of the scope clean with a soft, damp cloth.
5.2 Storage
Store the riflescope in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the flip caps are in place to protect the lenses from dust and scratches.
6. Troubleshooting
6.1 Reticle Not Illuminating
If the reticle does not illuminate, check the battery. Ensure it is correctly installed with the proper polarity and has sufficient charge. Replace the battery if necessary.
6.2 Blurry Image
If the image appears blurry, first adjust the diopter for reticle clarity, then adjust the side parallax knob for target image sharpness. Ensure the magnification is set appropriately for your viewing distance.
6.3 Point of Impact Issues
If you experience inconsistent point of impact, verify that the scope is securely mounted and that all rings and bases are tightened to the manufacturer's specifications. Ensure turrets are not accidentally bumped or moved. If issues persist, consult a qualified gunsmith.
