- Once zeroed, replace the protective caps to prevent accidental adjustments and protect the turrets.
Maintenance

- Keep the protective lens covers on when not in use to prevent dust and scratches.
- Clean the exterior of the sight with a damp cloth as needed. Avoid harsh chemicals.
2. Storage
- Store the sight in a cool, dry place away from direct sunlight and extreme temperatures.
- Always ensure the illumination is turned off to conserve battery life.
- If storing for extended periods, it is recommended to remove the battery to prevent leakage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Red/Green dot does not illuminate. | Battery is dead or incorrectly installed. | Check battery orientation (+ side up). Replace with a new CR2032 battery. Ensure illumination knob is not on '0'. |
| Dot appears dim or flickers. | Low battery power. | Replace the CR2032 battery. |
| Cannot zero the sight. | Mounting screws are loose; insufficient adjustment range. | Ensure mounting screws are tight. If still unable to zero, check for proper rail compatibility or consider a riser if needed. |
