This motorized scooter has an immunity of 20V/m which should protect it from
Electromagnetic Interference from Radio Wave Sources. These EM waves are invisible and
their strength increases as one approaches the source. All electrical conductors act as antennas
to the EM signals and to varying degrees, all power wheelchairs and scooters are susceptible to
electromagnetic interference. This EMI could result in unintentional movement and or erratic
control of the vehicle. Motorized scooters may be susceptible to EMI emitted from sources such
as radio and TV stations, amateur radio transmitters, two-way radios and mobile phones. The
interference can cause the scooters brake to release or move by itself.
Each motorized scooter can resist EMI up to a certain intensity called its “immunity level.”
The higher this level the greater the protection. Current technology is capable of achieving at
least 20V/m immunity level which will provide suitable protection from the more common
sources of radiated EMI.
Because EM energy rapidly becomes more intense as one moves closer to the source the EM
fields from hand-held radio wave sources are of special concern. It is possible to bring high
levels of EM energy very close to the scooter control system while using these devices.
WARNING
Do not operate hand-held personal communication devices such as CB radios or mobile phones
while the scooter is turned on.
Electromagnetic Interference ( EMI )
It is very important that you read this manual before using the scooter
for the first time including the following information regarding the
possible effects of Electromagnetic Interference ( EMI ) on the scooter.
