4. Maintenance
To ensure the longevity and optimal performance of your BOW MW190L mouse, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe the surface of the mouse. For stubborn dirt, slightly dampen the cloth with water or a mild cleaning solution. Avoid using harsh chemicals or abrasive materials.
- Battery Care: The mouse features an intelligent sleep mode to conserve battery life. It has a built-in 500mAh rechargeable lithium battery, offering approximately 500 days of standby time and 115 hours of continuous working time. Charge the mouse when the battery indicator is low. You can continue to use the mouse while it is charging.
- Storage: When not in use for extended periods, turn off the mouse to further conserve battery. Store the USB receiver in its dedicated compartment to prevent loss.

5. Troubleshooting
If you encounter issues with your BOW MW190L mouse, please refer to the following common solutions:
- Mouse Not Responding:
- Ensure the mouse is turned ON using the switch on the bottom.
- Check if the USB receiver is securely plugged into your computer's USB port.
- Try plugging the USB receiver into a different USB port.
- Ensure the mouse battery is charged. Connect it to a power source using the USB-C cable. - Intermittent Connection:
- Move the mouse closer to the USB receiver to rule out range issues (maximum 10m range).
- Avoid using the mouse on highly reflective or uneven surfaces. The optical sensor works best on opaque, consistent surfaces. - Cursor Movement is Erratic or Slow:
- Clean the optical sensor on the bottom of the mouse with a soft, dry cloth.
- Adjust the DPI setting using the DPI button to find a comfortable cursor speed. - Buttons Not Clicking:
- Ensure the mouse is powered on and connected.

7. User Tips
- Ergonomic Posture: When using the vertical mouse, ensure your forearm is relaxed and your wrist is in a neutral, handshake-like position. This helps maximize the ergonomic benefits and reduce strain.
- DPI Customization: Experiment with the 800, 1200, and 1600 DPI settings to find the sensitivity that best suits your workflow and screen resolution. Higher DPI is often preferred for larger monitors or faster cursor movement.
- Quiet Environment: Take advantage of the silent click buttons for a more peaceful work environment, especially in shared offices or late-night use.
- Battery Management: To prolong battery life, remember to turn off the mouse when not in use for extended periods. The intelligent sleep mode helps, but manual power-off is more effective for long breaks.
