EMI – ELECTROMAGNETIC INTERFERENCE
9.
WARNING:
It is important that you read this information regarding the possible 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, automatic doors,
etc.).

The driving performance of the EasyTravel Lite scooter can be influenced by
electromagnetic fields (e.g. those emitted by portable telephones, 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 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 EasyTravel Lite 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.
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.
