Troubleshooting

Problem	Solution
Mouse is not responding.	Ensure the mouse power switch is in the "ON" position. Check if the battery is correctly installed and has sufficient charge. Replace if necessary. Verify that the USB receiver is securely plugged into a working USB port on your computer. Try plugging the USB receiver into a different USB port. Restart your computer.
Cursor movement is erratic or slow.	Check the mouse's DPI setting and adjust it if needed. Ensure the mouse is used on a clean, non-reflective surface. Replace the battery. Ensure the mouse is within the 15-meter wireless range of the receiver and there are no significant obstructions.
Wireless connection is unstable.	Move the mouse closer to the USB receiver. Avoid using the mouse near other wireless devices (e.g., Wi-Fi routers, cordless phones) that might cause interference. Try plugging the USB receiver into a different USB port, preferably one on the front of your computer for better line of sight.
