The TOMY Launch Control has an adjustment knob and two switches, one for 100% and one for 0%.
With the two switches off, only the adjustment knob acts with which the amount of clutch applied can be adjusted, activating the 0% switch puts the clutch at 0%, activating the 100% switch puts the clutch at 100%
Exit Procedure
1. With both switches OFF try various outputs by adjusting the amount of clutch.
2. On the starting grid, set the 0% switch to OFF and the 100% switch to 100% to apply full clutch for full throttle.
3. When the traffic light turns green, deactivate the 100% switch so that the clutch that we had adjusted is applied.
4. Once the car has left, activate the 0% switch to remove all the clutch.
