  • Page 15: Emi

    CAUTION: It is very important that you read this information regarding the possible effects of electromagnetic interference on your electric KARMA Scooter. Electromagnetic Interference From Radio Wave Sources Powered vehicles may be susceptible to electromagnetic interference (EMI), which is interfering electromagnetic energy...
  • Page 16 3. EMI There are a number of sources of relatively intense electromagnetic fields in our everyday environment. Some of these sources are obvious and easy to avoid. Others are not apparent and exposure could be unavoidable. However, we believe that by following the warnings listed below, your risk to EMI can be greatly minimized.
  • Page 17 3. EMI Powered Vehicle Electromagnetic Interference (EMI) Because EM energy rapidly becomes more intense as one moves closer to the transmitting antenna (source), the EM fields from hand-held radio wave sources (transceivers) are of special concern. It is possible to unintentionally bring high levels of EM energy too close to the powered vehicle's control system while using these devices.
  • Page 18 There is no easy way to evaluate their effect on the overall immunity of the powered vehicle. 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.
