At the end of a ¼ mile run, you will see a reaction time at the top of 
the screen. This time begins when the final yellow light is displayed. 
The time between the final yellow and the green is a ½ second, so a 
perfect reaction time is a ½ second. The average person will see a 
response time of around 1 second.  You’ll get an “Illegal Start” 
message if you start before the green and you’re screen will turn red. 
You can still finish the run, but the screen will let you know that you 
started before the green light. 
Note: Along with the best speed and time being recorded for viewing in the 
Records section, your most recent run data will also be stored. This information 
can later be viewed using the Lightning® software to determine approximate 
horsepower, etc. 
5.  After the test is complete, press [MENU] to return to the Performance 
Menu.
