Radio Data Systems (RDS)Alternative (AF) Setting (Default: Disable)
The RDS AF setting can be found in the settings menu, accessible through Sena Device Manager or Sena Smartphone App.
When Radio station signals get too weak for good reception, with RDS AF enabled, the Sena radio
receiver re-tunes to a station with better reception. If RDS AF is disabled, you’ll have to find stronger stations manually.
