5. Opsætning
5.1. Battery Installation (HS510C)
- The HS510C comes with a CR2032 battery pre-installed.
- To replace, unscrew the battery tray cover on the right side of the sight using the T10 L key.
- Indsæt et nyt CR2032-batteri med den positive (+) side opad.

5.2. Mounting the Sight and Magnifier
Both the HS510C and HM3X utilize quick-detach (QD) mounts designed for Picatinny rails.
- Ensure the firearm is unloaded and pointed in a safe direction.
- Loosen the QD lever on both the sight and magnifier mounts.
- Place the HS510C sight onto the desired section of your Picatinny rail. Position it forward enough to allow space for the magnifier behind it.
- Close the QD lever. If the mount is too loose or too tight, adjust the tension screw on the opposite side of the lever using the T10 L key until a firm lock is achieved.
- Place the HM3X magnifier onto the rail directly behind the HS510C. Ensure proper eye relief for comfortable viewing.
- Close the QD lever for the magnifier, adjusting tension as needed.
