4. Maintenance
Battery Management:
To maximize battery life and ensure consistent performance:
- Power Off When Not in Use: Use the ON/OFF switches on both the keyboard and mouse when not in use for extended periods (e.g., overnight or when traveling).

- Battery Replacement: Replace batteries when performance degrades. The keyboard uses two AAA batteries, and the mouse uses one AA battery.
Cleaning:
To keep your combo clean and functioning optimally:
- Keyboard: Gently wipe the surface with a soft, damp cloth. For debris between keys, use compressed air. The keyboard has a spill-resistant design, but avoid submerging it in liquid.
- Mouse: Wipe the exterior with a soft, dry cloth. If tracking issues occur, clean the optical sensor on the underside with a cotton swab.
5. Troubleshooting
If you encounter issues with your MK270 combo, try the following troubleshooting steps:
No Connection or Intermittent Connection:
- Check USB Receiver: Ensure the USB receiver is securely plugged into a working USB port on your computer. Try a different USB port.
- Check Batteries: Verify that the batteries in both the keyboard and mouse are correctly inserted and have sufficient charge. Replace them if necessary.
- Power Switches: Make sure both the keyboard and mouse are switched to the 'ON' position.
- Distance and Interference: Ensure the devices are within the 10-meter operating range of the receiver. Move any large metal objects or other wireless devices that might cause interference.
- Re-pair Devices (if applicable): While the MK270 is typically plug-and-play, if issues persist, you may need to re-pair the devices using Logitech's Unifying software (available for download from the official Logicool/Logitech website).
Keys Not Responding or Mouse Not Tracking:
- Clean Devices: Check for any debris or obstructions under the keys or around the mouse's optical sensor. Clean as described in the Maintenance section.
- Mouse Surface: Ensure the mouse is being used on a suitable surface. Highly reflective or transparent surfaces may cause tracking issues.
Other Issues:
- Operating System Compatibility: Ensure your operating system (Windows XP, Vista, 7, 8, RT) is supported.
