Maintenance
Cleaning the Keyboard
To clean your keyboard, use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution. Avoid using abrasive cleaners, solvents, or aerosol sprays directly on the keyboard. For cleaning between keys, a can of compressed air can be used to remove dust and debris.
Battery Replacement
The keyboard is designed for extended battery life (up to 24 months). When the battery indicator light (if present) signals low power, or if you experience connectivity issues, replace the two AA batteries. Refer to the "Installing Batteries" section under Setup for instructions.
