Focusing the LH-4 / Setting the Diopter 1. Select an Unobstructed Background: Begin by looking at a clear, unobstructed background. Using the sky as a backdrop is recommended. 2. Rotate the Diopter Ring: While focusing on your chosen background, gently rotate the diopter ring on your scope. 3. Perform Adjustments in Short Intervals: Your eye naturally tries to refocus on the reticle, so it's important to adjust the diopter in short bursts. 4. Look Away Between Adjustments: After each adjustment, briefly look away from the scope to let your eye reset its focus on the sky. 5. Quickly Refocus on the Reticle: Quickly shift your gaze back to the reticle. This helps you assess if further diopter adjustments are needed. 6. Ensure Clarity and Stability: The reticle should appear sharp and stable. It should not move when you move your head. If this occurs, consider adjusting your parallax as needed. 7. Finalize the Setting: Once the reticle appears sharp and your eye doesn’t strain to focus, the diopter is correctly set. Your eye should not have to work to keep the reticle in focus during normal use.
