10. EMI – Electro-magnetic Interference
WARNING:
It is important that you read this information regarding the pos-
sible effects of electromagnetic interference on your EasyTravel Lite .
 The EasyTravel Lite scooter might disturb the operation of devices in
its environment that emit electromagnetic fields (e.g. alarm systems, au-
tomatic doors, etc.).
 The driving performance of the EasyTravel Lite scooter can be influ-
enced by electromagnetic fields (e.g. those emitted by portable tele-
phones, electricity generators or high power sources).
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 con-
trol 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 com-
mon sources of radiated EMI.
Your EasyTravel Lite 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
