5. Maintenance and Care

To ensure the longevity and optimal performance of your Logitech MK275 set, follow these maintenance guidelines:

• Cleaning: Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to clean the surfaces of the keyboard and mouse. Avoid harsh chemicals or abrasive materials.
• Spill Resistance: The keyboard is designed to be spill-resistant. In case of accidental spills, immediately turn off the keyboard, disconnect it, and allow it to dry completely before reuse. Do not immerse the keyboard in liquid.
• Battery Life: The keyboard offers up to 24 months of battery life, and the mouse up to 12 months. Battery life may vary based on usage. Replace batteries when performance degrades.
• Storage: When not in use for extended periods, turn off both the keyboard and mouse to conserve battery life. Store the USB Nano Receiver in the dedicated slot within the mouse (if available) or in a safe place to prevent loss.
• Environment: Avoid exposing the devices to extreme temperatures, direct sunlight, or high humidity.

6. Troubleshooting

If you encounter issues with your Logitech MK275 set, try the following solutions:

• No Connection/Lag:
  • Ensure the USB Nano Receiver is securely plugged into a working USB port.
  • Verify that both the keyboard and mouse are turned on.
  • Replace the batteries in both devices. Low battery can cause connection issues.
  • Move the keyboard and mouse closer to the receiver. The effective range is approximately 10 meters (33 feet).
  • Try plugging the receiver into a different USB port or a different computer to rule out port issues.
  • Avoid placing the receiver near other electrical devices that might cause interference (e.g., cordless phones, Wi-Fi routers).
• Keys Not Responding:
  • Check battery levels.
  • Ensure the keyboard is turned on.
  • If specific keys are not working, check for debris under the keycaps.
• Mouse Cursor Jumps or is Erratic:
  • Clean the optical sensor on the underside of the mouse.
