Motorized Scooter Electromagnetic Interference：
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 control system while using these devices. This can affect motorized
scooter movement and braking. Therefore, the warnings listed below are recommended
to prevent possible interference with the control system of the motorized scooter.
Safety information on electromagnetic interference
This electric vehicle was successfully tested in accordance with International standards
as to its compliance with Electromagnetic Interference (EMI) regulations. However,
electromagnetic fields, such as those generated by radio and television transmitters, and
cellular phones can influence the functions of electric vehicles. Also, the electronics used in
our vehicles can generate a low level of electromagnetic interference, which however will
remain within the tolerance permitted by law. For these reasons we ask you to please
observe the following precautions:
Warnings：
Danger of malfunction due to electromagnetic interference!
‧Do not switch on or operate portable transceivers or communication devices (such as
radio transceivers or cellular phones) when the vehicle is switched on.
‧Avoid getting near strong radio and television transmitters.
‧In case the vehicle should be set in motion unintentionally or the brakes are released,
switch it off immediately.
‧Adding electrical accessories and other components or modifying the vehicle in any way
can make it susceptible to electromagnetic interference. Keep in mind that there is no
sure way to determine the effect such modifications will have on the overall immunity
of the electronic system.
‧Report all occurrences of unintentional movement of the vehicle, or release of the electric
brakes to the manufacturer.
Important Information：
1.20 volts per meter (V/m) is a generally achievable and useful immunity level against
EMI (as of May 1994). The higher the level, the greater the protection.
2.The immunity level of this product is at least 20/Vm.
