Setup
1. Battery Installation
The Wraith 4K requires 4x AA batteries for operation. Locate the battery compartment, typically on the side or bottom of the scope. Insert the batteries according to the polarity indicators (+/-) inside the compartment. Close the battery cover securely.
Note: Battery life can vary. For extended use, consider an external power bank connected via the scope's power port.

2. Mounting the Riflescope
Attach the Wraith 4K to your rifle's Picatinny rail using the included fixed Picatinny mount. Ensure the mount is securely fastened to prevent movement during recoil. Proper eye relief (69mm) is crucial for comfortable and safe viewing; adjust the scope's position on the rail as needed.
Note: The scope is designed for integral mounting. If your rifle uses a different rail system, an adapter may be required (not included).
3. Initial Power On and Focus Adjustment
Press and hold the power button to turn on the device. Adjust the diopter ring (eyepiece focus) until the on-screen display and reticle are sharp. Then, adjust the objective lens focus ring to bring the target image into clear focus. This manual focus ensures optimal image clarity for varying distances.
Operating Instructions
1. Day and Night Mode Transition
The Wraith 4K can seamlessly switch between full-color daytime mode and digital night vision mode. Refer to the device's controls (buttons/menu) for the specific action to toggle between these modes. In night vision mode, the integrated IR flashlight can be activated to enhance visibility in low-light or complete darkness.
2. Magnification Adjustment
Use the digital magnification controls to adjust the zoom level from 4x to 32x. This allows for precise targeting at different ranges. Be aware that higher digital magnification may introduce some pixelation.
3. Reticle Selection and Customization
The scope offers 10 distinct reticle patterns and 9 color options to suit various preferences and shooting scenarios. Navigate through the menu to select your desired reticle and color. This customization allows for improved target acquisition and personal comfort.

4. Recording and Picture Capture
The Wraith 4K supports video recording in 4K or 1080p resolution and 4K still image capture. Ensure a compatible microSD card (not included) is inserted into the designated slot. Refer to the device's menu for controls to start/stop recording and capture photos.

5. Zeroing the Riflescope
Zeroing is essential for accurate shooting. The Wraith 4K features a digital zeroing function. Typically, this involves firing a shot, then using the scope's menu to adjust the reticle to the point of impact relative to the point of aim. Consult the on-screen prompts or the device's specific zeroing guide for detailed steps. The one-shot zero feature can significantly simplify this process.
Maintenance
1. Cleaning
Use a soft, lint-free cloth to clean the exterior of the scope. For lenses, use a specialized lens cleaning solution and cloth to avoid scratching. Do not use abrasive materials or harsh chemicals.
2. Battery Care
Remove batteries if the device will not be used for an extended period to prevent leakage. When using an external power source, ensure the connection is secure and protected from accidental bumps to prevent damage to the power port.
3. Storage
Store the riflescope in a cool, dry place, away from direct sunlight and extreme temperatures. Use the objective lens cover when not in use to protect the lens.
4. Water Resistance
The Wraith 4K is IP55 water-resistant, meaning it is protected against dust ingress and low-pressure water jets from any direction. It is not designed for submersion. Avoid exposing the device to heavy rain or prolonged wet conditions.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Blurry image in day mode (especially indoors) | Environmental factors (e.g., heat haze), improper focus. | Adjust objective lens focus. Test in different environments. Ensure proper diopter adjustment. |
| Short battery life | High power consumption, old/low-quality batteries. | Use fresh, high-quality AA batteries. Consider using a compatible external power bank for extended operation. |
| Reticle not centered on screen after zeroing | Mounting height/angle. | This is a characteristic of some digital scopes where the reticle moves digitally. If it significantly impacts usability, consider adjusting the scope's physical height or angle on the rail (e.g., with a riser or shims) to bring the reticle closer to the optical center. |
| External power port issues | Physical damage from bumps or improper connection. | Ensure careful handling when connecting/disconnecting external power. Secure the cable to prevent strain or accidental dislodgement. |
| No image/power | Dead batteries, incorrect battery insertion, device malfunction. | Replace batteries. Check battery polarity. Ensure battery compartment is closed. If problem persists, contact support. |
