The fast developement of electronics, mostly in the area of communication, has flooded our world
with electromagnetic (radio) waves transmitted by TV, radio, laptops, microwaves and pacemakers.
These electromagnetic waves are invisible and get stronger the closer one gets to a source. If these
electromagnetic waves cause electrical appliances to stop functioning correctly or even completely
stop working, this is called Electromagnetic Interference (EMI) or Radio Frequency Interference
(RFI).
All electrical vehicles, including scooters, are susceptible for Electromagnetic Interference / Radio
Frequency Interfenrece (RFI). This can result in unexpected movements of your scooter. Should
any unintended movements occur, or the brakes don’t work as normal, turn off your scooter
immediately. The FDA has ruled that every scooter should be able to resist EMI / RFI up to a certain
level. The higher the level of interference it can withstand, the better the protection against EMI
/ RFI is. This is measured in volts per meter (V/m). The minimum resistance level against EMI / RFI
should be 20 V/m. This product has been tested and found to have a resistance level of 20 V/m.

4.6 EMI / RFI
•
Do not use personal electronic communication devices like a mobile phone, when using your
scooter.
•
Be extra careful when in the neighbourhood of radio and TV towers.
•
Turn off your scooter when you are standing still for a longer time.
•
If unintended movement or brake release occurs, turn off the scooter as soon as it is safe to
do so.
•
Report all incidents of unintended movement or brake release to the manufacturer and note
wether there is a radio wave source nearby.
•
Be aware that adding accessories or components, modifying the scooter may make it more
susceptible to interference from radio wave sources. (Note: there is no easy way to evaluate
their effect on the overall immunity of the scooter).
