■ 2.4 EMI
 This portion of the content will provide the user with basic information that describes
the problems with EMI, known sources of EMI, protective measures either to lessen
the possibility or exposure or to minimize the degree of exposure, and suggested
action should unexpected or erratic movement occur.
 WARNING!
It is very important that you read this information regarding the possible effects of
electromagnetic interference on your electric scooter.
■ ELECTROMAGNETIC INTERFERENCE (EMI) FROM RADIO WAVE
SOURCES
 Powered vehicle 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 radios, and cellular phones.
The interference (from radio wave sources) can cause the powered vehicle to release
its brakes, move by itself, or move in unintended directions. It can also permanently
damage the powered vehicle's control system. The intensity of the interfering EM
energy can be measured in volts per meter (V/m). Each powered vehicle can resist
EMI up to a certain intensity. This is called its "immunity level". The higher the
immunity level, the greater the protection. At this time, current technology is capable
of achieving at least a 20 V/m immunity level, which would provide useful protection
from the more common sources of radiated EMI. This powered vehicle model as
shipped, with no further modification, has an immunity level of 20 V/m without any
accessories.
 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 unavoidable. However, we believe that by following
the warning listed below, your risk to EMI will be minimized.
The sources of radiated EMI can be broadly classified into three types:
4. Hand-held portable transceivers (transmitter-receivers with the antenna mounted
directly on the transmitting unit. Examples include citizens band (CB) radios, "walkie
talkie", security, fire, and police transceivers, cellular telephones and other personal
communication devices.
5. Medium-range mobile transceivers, such as those used in police cars, fire trucks,
ambulances and taxis. These usually have the antenna mounted on the outside of the
Vehicle.
Long-range transmitters and transceivers, such as commercial broadcast transmitter
6.
(radio and TV broadcast antenna towers) and amateur (HAM) radios.
