f) Assembling the Front Wheel

g) Wiring

5. Operation

Put the switch in the “ON”-position. Place the device on the floor and verify whether it moves smoothly. The KSR1

should back up to the left when you clap your hands. The KSR1 will subsequently move forward in a straight line

again. Adjust “VR” with a screwdriver to change the microphone’s sensitivity. Turn the screwdriver to the right for

increased sensitivity and vice versa.

6. Troubleshooting

1. Make sure all components on the PCB are in the right position. Pay particular attention to the polarity of the

microphone, the transistors and capacitors.

2. Check the wiring.

3. Adjust the nylon nut (n°17) on the front wheel if the car keeps veering to the left.

4. The noise from the gearbox may prevent the microphone from receiving the signal. Grease face gear 36T/14T

(white) and the metal shaft (n°3) to reduce the noise.

5. Do not grease metal shaft (n°4) and gears 36T/0T (white) and 36T/14T (red)
