6. Operation

Put the switch in the “ON”-position. Place the device on the floor and verify whether it moves smoothly. Clap your
hands repeatedly to make the KSR2 execute the following steps : stop

→ move forward to the left → stop → move

forward to the right

→ stop → move forward in a straight line. Adjust “VR” with a screwdriver to change the

microphone’s sensitivity. Turn the screwdriver to the right for increased sensitivity and vice versa.

7. 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, capacitors and the IC’s.

2. Check the wiring.
3. 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.

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