- Spills: While the keyboard design offers some protection against light splashes, avoid direct exposure to liquids. In case of a spill, immediately disconnect the device from your computer and allow it to dry completely before reconnecting.
- Storage: Store the keyboard and mouse in a clean, dry environment away from extreme temperatures and direct sunlight.
