Maintenance
- Cleaning: Use a soft, dry, lint-free cloth to clean the surfaces of both the mouse and keyboard. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid excessive moisture.
- Trackball Cleaning (Mouse): Periodically remove the trackball (usually by pushing it out from the bottom or a dedicated opening) and clean the trackball and the internal sensors with a cotton swab or compressed air to ensure smooth operation.
- Storage: When not in use, especially during travel, fold the keyboard to protect the keys. Store both devices in a cool, dry place, away from direct sunlight and extreme temperatures.
- Battery Care: To prolong battery life, avoid fully discharging the devices frequently. Charge them when the low battery indicator appears. If storing for a long period, charge them to about 50% every few months.
