Questions about Sena RC4 remote control

The RC4 remote control is designed to be compatible with most Sena devices using Bluetooth 4.1 or higher. However, I don't have any specific information on its compatibility with the Sena SRL Mesh or SRL 2 intercom. It is recommended that you consult the official Sena documentation or contact their support for specific compatibility details.

Works with a Schuberth SC1S, so probably yes. Please note that mine yesterday came with a dead battery inserted and a new one packed next to it that i didn't notice, and I worried hours until i bought another new battery fearing it was DoA.

Yes, according to my research, this remote is suitable for the Schuberth SC1. Both devices support Bluetooth 4.1.
