Maintenance Features

The R2 EVO includes features for software updates and troubleshooting to ensure optimal performance.

Downloadable Sena Software:

Sena Cycling App: Available on Google Play Store and App Store, this app allows users to control various helmet functions, including channel settings for Mesh Intercom and LED taillight control.
Sena Device Manager: Downloadable from sena.com, this software facilitates firmware upgrades and device configuration settings, ensuring the helmet stays up-to-date with the latest features and improvements.
Firmware: Firmware updates are available through sena.com to enhance functionality and address any issues.

Troubleshooting:

Factory Reset: A factory reset can be performed by holding the Center button for 10 seconds to enter the configuration menu, then tapping the (+) button twice to select "Factory Reset," and finally tapping the Center button once to confirm. This resets the Bluetooth system to its original factory settings.
Fault Reset: In case of a system malfunction, a fault reset can be performed by inserting a pin into the pinhole fault reset button located near the DC power charging and firmware upgrade port. It's important to note that a fault reset does not restore the Bluetooth system to factory default settings.

The helmet's design also incorporates practical elements for comfort and fit, such as a chinstrap pad, strap adjuster, buckle, and O-ring, all of which contribute to a secure and comfortable wearing experience. The chinstrap tension can be adjusted to ensure a snug fit, and the helmet should be positioned correctly on the head, covering the forehead, with the strap adjuster centered below the ears and the buckle under the chin.
