  • Page 16: Emi/Rfi

    If the electric vehicle acts abnormally or the brake system fails, turn off the power source as soon as safely possible. Remember that the installation of non-genuine KARMA parts makes it difficult to predict what effects radio waves will have on the vehicle. (Note: it is not possible to make a direct calculation how radio waves will influence the vehicle).
  • Page 17 TV stations, amateur radio (HAM) transmitters, two-way radios, and cellular phones. The interference (from radio wave sources) can cause the powered vehicle to release its brakes, move by itself, or move in unintended directions. It can also permanently damage the powered vehicle's control system. The intensity of the interfering EM energy can be measured in volts per meter (V/m).
  • Page 18 5. Report all incidents of unintended movement or brake release to your powered vehicle dealer or KARMA, and note whether there was a source of EMI nearby.  Important Information 1. 20 Volts per meter (V/m) is a generally achievable and useful immunity level...
