Operating Instructions
1. Reflex Sight Operation
Power On/Off and Brightness Adjustment:
- Rotate the rotary switch located on the side of the sight.
- Turning the switch to 'G' (Green) or 'R' (Red) will power on the sight.
- Continue rotating to increase or decrease the brightness level (1-5).
- Set the switch to '0' to power off the sight.
Reticle Pattern Selection:
- Use the reticle selector knob located at the front of the sight to cycle through the 4 available reticle patterns.

2. Laser Sight Operation
Standard Operation:
- Press the button on the end cap of the laser sight to turn it on or off.
Pressure Switch Operation:
- The pressure switch typically has two buttons: one for momentary activation (laser on only while pressed) and one for constant on/off. Refer to the specific pressure switch instructions for details.
3. Zeroing and Adjustment
Zeroing is the process of aligning your sight with the point of impact of your projectile. This should be done at a safe shooting range.
Reflex Sight Adjustment:
- Elevation Adjustment: Use the provided Allen wrench to turn the 'UP' adjustment screw (usually on top of the sight). Turning clockwise moves the point of impact down; counter-clockwise moves it up.
- Windage Adjustment: Use the provided Allen wrench to turn the adjustment screw on the side of the sight. Turning clockwise moves the point of impact left; counter-clockwise moves it right.
Laser Sight Adjustment:
- The laser sight has its own small adjustment screws for windage and elevation. Use a small Allen wrench (often included) to make these adjustments.
- Adjust the laser until its dot aligns with the point of impact or the center of your reflex sight's reticle at your desired zeroing distance.

Maintenance
- Cleaning Lenses: Use the provided cleaning cloth or a soft, lint-free cloth to gently wipe the lenses. For stubborn dirt, use a small amount of lens cleaning solution. Avoid abrasive materials.
- Body Cleaning: Wipe the body of the sight with a damp cloth to remove dirt and debris.
- Battery Replacement: Replace batteries when the reticle or laser appears dim or fails to illuminate. Always dispose of used batteries responsibly.
- Storage: Store the sight in a cool, dry place when not in use. Remove batteries if storing for extended periods to prevent leakage.
- Weather Resistance: While the sight is waterproof and fog proof, prolonged exposure to extreme conditions should be avoided. Ensure all caps and covers are securely tightened.
