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.
