8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Mouse not responding | Mouse is off, low battery, incorrect connection mode, receiver not plugged in (2.4G), Bluetooth not paired. | Ensure mouse is on. Charge the mouse. Switch to the correct connection mode. For 2.4G, ensure receiver is securely plugged in. For Bluetooth, re-pair the mouse. |
| Cursor movement is erratic or slow | Low CPI setting, dirty optical sensor, uneven surface. | Increase CPI using the CPI button. Clean the optical sensor on the bottom of the mouse. Use the mouse on a smooth, opaque surface or a mouse pad. |
| Cannot connect via Bluetooth | Mouse not in pairing mode, device's Bluetooth is off, interference. | Ensure mouse is in BT pairing mode (rapidly flashing blue light). Check if your device's Bluetooth is enabled. Move closer to the device or away from other wireless devices. |
| Forward/Back buttons not working on Mac | Mac OS does not natively support these functions for third-party mice without additional software. | This is a known limitation with Mac OS. Consider using third-party software or drivers if available for extended functionality. |
