Maintenance
- Cleaning: Use a soft, dry cloth to clean the surfaces of the keyboard and mouse. For stubborn dirt, a slightly damp cloth with mild soap can be used, ensuring no liquid enters the device.
- Spill Resistance: The keyboard features a spill-resistant design, meaning it can withstand minor liquid spills (up to 60 ml). However, it is not waterproof and should not be submerged in any liquid. In case of a spill, immediately power off the keyboard and allow it to dry completely before reuse.
- Battery Replacement:
The keyboard has an approximate battery life of 36 months, and the mouse has an approximate battery life of 12 months. When performance degrades or the low battery indicator (if present) illuminates, replace the batteries with new AAA (keyboard) and AA (mouse) alkaline batteries. Always dispose of used batteries responsibly.
- Power Management: Utilize the on/off switches on both the keyboard and mouse when not in use for extended periods to conserve battery life.

The keyboard is designed to be spill-resistant, capable of handling small liquid splashes. Note that it is not waterproof and should not be immersed.
