9. EMI – ELECTROMAGNETIC INTERFERENCE
CAUTION: It is important that you read this information regarding the
possible effects of electromagnetic interference on your Easy Fold Deluxe.
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
radios, 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
system. 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 mobility 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 Lexis Light as shipped, with no further modification, has an
immunity 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
unavoidable. However, we believe that by following the warnings listed
below, your risk to EMI will be minimized.

Lexis Light –ET1B User’s Manual T.Rev. 0512 PM 20
The sources of radiated EMI can be broadly classified into three types:
1) Hand-held portable transceivers (transmitters-receivers) with the
antenna mounted directly on the transmitting unit. Examples include
citizens band (CB) radios, "walkie-talkies”, security, fire, and police
transceivers, cellular telephones, and other personal communication
devices.
**NOTE: Some cellular telephones and similar devices transmit signals
while they are ON, even when not being used;
2) 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; and
3) Long-range transmitters and transceivers, such as commercial
broadcast transmitters (radio and TV broadcast antenna towers) and
amateur (HAM) radios.
NOTE: Other types of hand-held devices, such as cordless phones, laptop
computers, AM/FM radios, TV sets, CD players, and cassette players, and
small appliances, such as electric shavers and hair dryers, so far as we know,
are not likely to cause EMI problems to motorized scooters.
Motorized scooter Electromagnetic Interference (EMI)
Because EM energy rapidly becomes more intense as one moves closer to
the transmitting antenna (source), the EM fields from hand-held radio wave
sources (transceivers) are of special concern. It is possible to unintentionally
bring high levels of EM energy very close to the motorized scooter’s control
system while using these devices. This can affect the scooter’s movement
and braking. Therefore, the warnings listed below are recommended to
prevent possible interference withthe control systemof your Lexis Light.
