Helmet Aware
The helmet aware beacon and mounting
            adhesive comes shipped with the owner’s manual. This allows
            parents to mount to a helmet. The helmet aware beacon should be mounted
            on a flat surface on the helmet.
The
            display will issue a low battery message if the beacon is below 10%
            battery level. Parents can replace the battery beacon with a CR2032. 

To replace the battery remove 2 screws
            from the enclosure and then split the beacon apart with a small standard
            screw driver.
Helmet aware comes disabled
            from factory and must be enabled by parent.
