The Sena 10S is a Bluetooth 4.1 communication system designed for motorcycle helmets. It supports multi-way intercom, music sharing, and FM radio. Key operations are performed using the Jog Dial and Phone Button. Ensure the unit is fully charged before first use and that the firmware is updated via the Sena Device Manager.
Installation
The headset can be mounted using either the Clamp Unit or the Glued Surface Mounting Adapter.

Installing the Main Unit

- Clamp Unit: Loosen the two screws on the back plate, insert the plate between the helmet's internal padding and external shell, then tighten the screws. Attach the main unit until it clicks.
- Glued Surface Mounting Adapter: Clean the helmet surface, peel off the adhesive cover, and attach the adapter. Allow 24 hours for maximum adhesion before attaching the clamp unit.
Installing Speakers and Microphones
- Speakers: Attach the hook and loop fasteners to the ear pockets inside the helmet, then attach the speakers. Use speaker pads if the helmet has deep ear pockets.
- Microphones: Attach the wired boom microphone or wired microphone to the inside of the helmet using the provided hook and loop fasteners. Ensure the microphone receiver is positioned near your mouth.
Getting Started
Powering On/Off: Press the Phone Button and the Jog Dial simultaneously.

Volume Adjustment: Rotate the Jog Dial. Volume is maintained independently for each audio source.
