Emi / Rfi - Excel Galaxy II User Manual

4.7. 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 links, 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.
EMI / RFI recommendations

Do not turn on or use hand-held personal electronic communication devices such as a
phones, walkie-talkies, and CB radio's while driving on your scooter;

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.
