4.9 EMI / RFI
The rapid development of electronics, especially in the area of communications,
has saturated our environment with electromagnetic (radio) waves that are
emitted by television transmitters, cellular phones, citizen’s band radios (CBs),
amateur radios (ham radios), wireless computer left, microwave transmitters,
paging transmitters, etc. These electromagnetic (EM) waves are invisible and
increase in strength the closer one gets to the source of transmission. When
these energy waves act upon electrical devices and cause them to malfunction or
to function in an erratic or uncontrolled manner, they are referred to as
Electromagnetic Interference (EMI) of Radio Frequency Interference (RFI).
EMI / RFI and your scooter
All electrically powered vehicles, including scooters are susceptible to
Electromagnetic Interference / Radio Frequency Interference (EMI / RFI). This
interference could result in abnormal, unintended movement of your scooter.
Warning:
Unintended movement or brake release could cause an accident or injury.
The FDA has determined that each make and model of scooter can resist EMI/
RFI to a certain level. The higher the lever of resistance, the greater the degree of
protection from EMI/ RFI – measured in volts per meter (V/m). The FDA has also
determined that current technology is capable of providing 20 V/m of resistance
to EMI/ RFI, which would provide useful protection against common sources of
interference. This product has been tested and has passed an immunity lever of
20 V/m.
