Maintenance Tips
-
Clean lens carefully: Use a microfiber cloth and lens-safe cleaner to preserve clarity and the green dot’s crisp visibility.
-
Keep emitter window clear: Remove dust and debris to ensure consistent dot projection and accuracy.
-
Check mounting screws: Regularly verify tightness for reliable zero retention under recoil.
-
Battery maintenance: Replace CR2032 as needed and remove during long-term storage to prevent leakage.
-
Use proper brightness settings: Lower settings extend battery life and improve visibility in low-light conditions.
-
Protect from moisture & dirt: Wipe down after exposure, even though it’s water-resistant and rugged.
-
Avoid touching glass: Fingerprints can distort the dot and reduce performance.
-
Minimize impacts: Durable micro design, but avoiding drops helps maintain internal alignment.
