S3 rear light and intercom basics
Rear light behavior, slow flash runtime, and basic intercom demo guidance for S3.
S3 is listed with rear light support and a slow flash mode with up to 18 hours runtime.
The comparison data marks S3 as supporting intercom. Keep pairing steps close to the product manual once the final firmware is confirmed.
For group rides, test communication before entering traffic and keep volume low enough to remain aware of surroundings.
If intercom pairing fails, restart the helmet, keep devices close together, and retry pairing from a clean state.
