IV. EMI INFORMATION
Electromagnetic interference (EMI) tests have shown to produce adverse effects on the
performance and control of electrically powered mobility devices.
EMI can be produced from different sources such as cellular phones, two-way radios, radio
stations, television stations, amateur radio transmitters (HAM), wireless computer links,
microwave signals, paging transmitters, and transceivers used by emergency vehicles.
The EMI waves can cause unintentional movement of the scooter, or damage to the
controller. Every electrical powered mobility device has a resistance to EMI. The higher the
resistance level the greater the protection. The intensity of the interference can be measured
in volts per meter, V/m.
At this time, current technology is capable of achieving an immunity level of 20 V/m, which
provides protection from more common sources of EMI. Your scooter, with no modifications,
has an immunity level of 20 V/m.
EMI becomes more intense as you move closer to the source. The EMI produced from hand-
held radios are of special concern. It is possible to unintentionally bring high levels of EMI very
close to the sc
ooter’s control system, effecting your movement and braking. The warnings
listed below are recommended to prevent possible interference with the control system of
your scooter.
WARNING – Do not operate hand-held transceivers such as CB (citizens
band) radios, or turn on personal communication devices, such as cellular
phones, while the scooter is powered on.
WARNING – Be aware of nearby transmitters, such as radio or television
stations, and avoid close proximity.
WARNING – If you experience unintended movement or brake release occurs,
power off as soon as it is safe. Please report EMI incidents to Drive DeVilbiss.
