• Charging: Use only the provided USB-C cable for charging. Do not attempt to charge the helmet if it is wet or damaged.

Before first use, fully charge your Sena S1 helmet. Connect the supplied USB-C cable to the charging port on the helmet and to a USB power source (e.g., computer USB port or wall adapter). The LED indicator will show charging status.

A properly fitted helmet is crucial for safety and comfort. Place the helmet on your head and adjust the rear retention system using the dial until it feels snug. Adjust the side straps so they form a 'V' shape just below your ears. Fasten the chin strap securely, ensuring it is tight enough that the helmet does not move excessively when you shake your head, but not so tight as to cause discomfort.
