Setup Instructions
Follow these steps to pair your MCHOSE wireless mouse with the 8K USB Wireless Receiver:
- Ensure your compatible MCHOSE wireless mouse is powered on and its switch is set to the [2.4G] mode.
- On the mouse, press and hold the left, middle, and right mouse buttons simultaneously for approximately 5 seconds. The mouse's indicator light will begin flashing yellow, indicating it is in pairing mode.
- Connect the Type-C end of the provided data cable into the corresponding port on the 8K receiver.
- Plug the standard USB end of the data cable into an available USB port on your computer (PC/Mac/Laptop).
- Bring the mouse close to the receiver. The pairing process is successful when the mouse's indicator light turns off.

Operating Instructions: Polling Rate Adjustment
The MCHOSE 8K USB Wireless Receiver supports adjustable polling rates to optimize performance for various tasks, from office work to competitive gaming.
- 8000Hz Polling Rate: Provides 8,000 signals per second, significantly reducing latency to 0.125ms for highly accurate and responsive cursor control. This is ideal for competitive gaming where precision is critical.
- Smart Polling Rate Adjustment: You can customize the polling rate settings using the official MCHOSE Driver Software. Available polling rates include 125Hz, 250Hz, 500Hz, 1000Hz, 2000Hz, 4000Hz, and 8000Hz. Adjust the rate to suit your specific usage scenario.

Troubleshooting
- Device Not Pairing:
Ensure the mouse is in 2.4G mode and the pairing sequence (holding left, middle, and right buttons) is performed correctly until the yellow light flashes. Verify the receiver is securely plugged into a functional USB port on your computer. Try a different USB port if necessary.
- Intermittent Connection:
Ensure the receiver is not obstructed and is within close proximity to the mouse. Avoid placing the receiver near other wireless devices that may cause interference. Update your mouse's firmware and MCHOSE Driver Software to the latest versions.
- Polling Rate Issues:
Confirm that the MCHOSE Driver Software is installed and updated. Use the software to select your desired polling rate. Some systems or applications may not fully support 8000Hz; try a lower polling rate (e.g., 4000Hz or 1000Hz) to see if the issue resolves.
Maintenance
To ensure optimal performance and longevity of your MCHOSE 8K USB Wireless Receiver:
- Keep the receiver clean and free from dust. Use a soft, dry cloth for cleaning.
- Avoid exposing the receiver to extreme temperatures or humidity.
- Handle the receiver gently to prevent physical damage to the ports or casing.
