General Tips
Mount sensors on block as high as possible near cylinder head.
Try not to mount near rockers as high tappet noise will occur.
Keep wiring and sensors away from exhaust heat as much as possible and if needed make heat shield to
protect them.
If the two sensors are mounted in different positions, use the sensor balance to even out the sound, so that the
sound is even in the headset.
If 1 sensor is to be used only, select sensor 1 on sensor select switch and use sensor 1 connector only.
Use the volume control to adjust the overall volume in the headset and set to a comfortable level.
Disconnect power supply from battery when not in use or your battery will go flat.
Treat knock sensors with the utmost care. Do not drop them.
The unit has a selectable switch for 1 or 2 sensors.
