9. EMI – ELECTROMAGNETIC INTERFERENCE
CAUTION: It is important that you read this information regarding the possi-
ble effects of electromagnetic interference on your
Easy Travel Elite
.
Electromagnetic Interference (EMI) From Radio Wave Sources
Motorized scooters may be susceptible to electromagnetic interference (EMI),
which is interfering electromagnetic energy (EM) emitted from sources such
as radio stations, TV stations, amateur radio (HAM) transmitters, two-way ra-
dios, and cellular phones. The interference (from radio wave sources) can
cause scooters to release their brakes, come to a sudden stop, or move in an
uncontrolled manner. It can also permanently damage a scooter’s control sys-
tem. The intensity of the interfering EM energy can be measured in volts per
motor (V/m). Each Motorized scooter can resist EMI up to a certain intensity.
This is called its “immunity level". The higher the immunity level, the greater
the protection. The FDA has stated that all newly manufactured electric mobil-
ity vehicle models should have a resistance of at least 20 V/m, which would
provide a reasonable degree of protection from the more common sources of
radiated EMI.
Your
Easy Travel Elite
as shipped, with no further modification, has an im-
munity level of 20 V/m. This immunity was tested with the inclusion of these
accessories: a utility basket with a spare battery-pack and the charger unit
carried inside it.
There are a number of sources of relatively intense electromagnetic
fields in the everyday environment. Some of these sources are obvious
and easy to avoid. Others are not apparent and exposure is unavoid-
able. However, we believe that by following the warnings listed below,
your risk to EMI will be minimized.
