5. Maintenance

5.1 Cleaning the Mouse

To maintain optimal performance and hygiene, regularly clean your MX Master 2S mouse:

• Use a soft, lint-free cloth slightly dampened with water or an alcohol-based cleaner to wipe the surface.
• Avoid harsh chemicals or abrasive materials.
• Use a dry cotton swab or compressed air to clean around the scroll wheel and sensor area.

5.2 Battery Care

The integrated Lithium Polymer battery is designed for long life. To prolong battery health:

• Avoid extreme temperatures.
• Charge the mouse when the battery indicator is low, but it is not necessary to fully discharge it before recharging.

6. Troubleshooting

6.1 Mouse Not Responding

• Ensure the mouse is turned on.
• Check battery level and charge if necessary.
• If using the Unifying Receiver, ensure it is securely plugged into a USB port. Try a different USB port.
