12.0 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 (CB’s), 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) or 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 can 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 / RFT
– 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 interference. This product has been tested and has passed an immunity level of 20
V/m.
EMI / RFI recommendations

Do not turn on or use hand-held personal electronic communication devices such as cellular
phones, walkie-talkies and CB radios while your scooter is turned on;

Be aware of any nearby transmitters (radio, television, microwave, etc.) on your intended route
and avoid operating your scooter close to any of those transmitters;

Turn off the power if your scooter is going to be in a stationary position for any length of time;

Be aware that adding accessories or components or modifying your scooter may make it more
susceptible to EMI / RFI;
WARNING! Turn off your scooter as soon as it is safely possible if unintended or
uncontrollable motion occurs or if unintended park brake release occurs.
