To mount the CNV150, first ensure the rifle is unloaded. Align the mounting bracket on the scope with the rail on your rifle, then secure it using the provided screws. Make sure it's tightly fastened to avoid shifting during use.
Check if the batteries are installed correctly and fully charged. If the problem persists, inspect the battery compartment for corrosion or damage and clean it if necessary. Replace the batteries and try again.
To adjust the focus, rotate the eyepiece until the image becomes clear. For fine-tuning, use the objective lens focus ring. Make adjustments slowly to avoid overshooting the optimal focus point.
Store the scope in a cool, dry place away from direct sunlight. Remove the batteries to prevent leakage, and keep the lens caps on to protect the optics from dust and scratches.
Use a soft, lint-free cloth and a lens cleaning solution specifically designed for optics. Gently wipe the lenses in a circular motion, avoiding excessive pressure to prevent scratches.
The expected battery life is approximately 20 hours of continuous use. To extend battery life, turn off the unit when not in use, avoid using high brightness settings unnecessarily, and use fresh, high-quality batteries.
No, the CNV150 is designed for low-light conditions. Using it in daylight can damage the internal components. Always use the lens cap with the built-in pinhole for daytime use if necessary.
Ensure that both the eyepiece and objective lenses are correctly focused. Check for any dirt or obstructions on the lenses and clean them if needed. If the problem persists, the scope may require professional servicing.
In complete darkness, activate the infrared (IR) illuminator and look through the scope. You should see an improvement in image brightness. If not, check the IR settings and ensure the illuminator is not obstructed.
Regularly clean the lenses and body with appropriate materials, store it properly, and periodically check for any signs of damage or wear. Avoid exposing the scope to extreme temperatures and humidity.
