Usage recommendations

Place the USB receiver in a direct line of sight with the keyboard and mouse where possible to maintain a stable wireless connection. Keep the keyboard and mouse on a clean, flat surface and avoid placing heavy objects on the keys. Replace batteries promptly if input becomes intermittent. For extended typing sessions, adjust chair and desk height to support neutral wrist and forearm positions.
