The vehicle position LED   moves up the column as a 

vehicle gets closer to your bike. The threat level LED 

changes color based on the potential level of threat. Green 

indicates no vehicle is detected. Amber indicates a vehicle is 

approaching. Red indicates a vehicle is advancing at a high 

rate of speed.

The Edge device beeps if audible tones are turned on in the 

settings. Your device has alert tones for several features. The 

alert tone for approaching vehicles has a unique sound. The 

device beeps one time when the first vehicle is detected. After 

the threat is cleared, the device beeps again when another 

vehicle is detected.
