Charging and Power Management

- Low Battery Indicator: A dedicated indicator light will alert you when the battery level is low, signaling that charging is required.

Maintenance
To ensure optimal performance and longevity of your seenda keyboard and mouse combo, follow these maintenance guidelines:
- Cleaning: Use a soft, dry, lint-free cloth to clean the surfaces of the keyboard and mouse. For stubborn dirt, slightly dampen the cloth with water or a mild cleaning solution. Avoid harsh chemicals or abrasive materials.
- Silicone Cover: The included silicone keyboard cover can be washed with mild soap and water, then air-dried, to keep your keyboard protected from dust and spills.
- Storage: When not in use for extended periods, store the devices in a cool, dry place. Ensure they are powered off to conserve battery life.
- Avoid Liquids: Do not expose the devices to excessive moisture or immerse them in water.
