EMI/RFI WARNINGS
Laboratory te t performed by the Food and Drug Admini tration (FDA) have hown that radio wave can cau e
unintended motion of electric cooter . Radio wave are a form of electromagnetic energy (EM). When electro-
magnetic energy adver ely affect the operation of an electrical device, that adver e effect i called Electromag-
netic Interference (EMI) or Radio Frequency Interference (RFI).
EMI/RFI FREQUENTLY ASKED QUESTIONS (FAQS)
The following FAQ ummarize what you hould know about EMI/RFI. U e thi information to minimize the ri k
that EMI/RFI will adver ely affect your Sidekick.
Where do radio waves come from?
Radio wave are emitted from the antenna of cellular phone , mobile two-way radio ( uch a walkie-talkie and
CB ), radio tation , TV tation , amateur radio (HAM) tran mitter , wirele computer link , microwave ource ,
and paging tran mitter . Radio wave are a form of EM. Becau e EM i more inten e clo er to tran mitting
antenna ( ource of emi ion), the EM field from two-way radio are of pecial concern to electric cooter u er .
f EM /RF affects my Sidekick, what kind of motion should expect?
Thi i difficult to predict. The an wer would depend on a number of factor :
nThe trength of the radio wave .
nThe con truction of your particular Sidekick.
nThe location of your Sidekick (whether it i on level ground or on an incline).
nWhether or not your Sidekick i in motion.
The motion of any electric cooter affected by EMI/RFI can be erratic. The cooter may come to a udden top or
move in an uncontrolled manner. Al o, it i po ible for EMI/RFI to relea e the brake of an electric cooter. Some
inten e EMI/RFI can even damage the control y tem component of an electric cooter.
s there any way to know for certain whether or not radio waves are the cause of any unintended motion
of my Sidekick?
Unfortunately, EMI/RFI may be difficult to recognize, ince the ignal from radio ource are invi ible and may be
intermittent. However, the FDA recommend that you report all incident of unintended motion or unintended
brake relea e of your electric cooter to the cooter manufacturer and, if po ible, determine whether or not
there wa a radio wave ource nearby at the time of the incident.
One precaution you can take again t inadvertent motion of your Sidekick i to make certain that you or omeone
el e i not the cau e of the unintended motion.
nTurn off your Sidekick by removing the key from the key witch when you are getting on or off of your Sidekick.
nNever leave the key in the key witch of an unattended Sidekick.
By following the e tep , you greatly reduce the ri k of you or anyone el e inadvertently bumping the throttle
control lever and cau ing the Sidekick to move unintentionally.
Are all scooters susceptible EM /RF ?
Each make and model of electric cooter differ in it ability to re i t EMI/RFI. That i , each cooter ha a
particular level of re i tance to EMI/RFI. Thi re i tance i mea ured in volt per meter (V/m). A higher re i tance
level offer greater protection again t EMI/RFI. In other word , an electric cooter with a high re i tance level i
le likely to be affected by a trong radio ource than i an electric cooter with a low re i tance level.
