Regarding EMI
Important Technical Information regarding
Electromagnetic Interference (EMI)
The intensity of interference from electromagnetic
energy is measured in volts per meter (v/m), which
refers to the strength of the electrical source (volt-
age) as it relates to the distance away from the
object being considered (in meters). Resistance
of a scooter/wheelchair to certain EMI intensity is
commonly called its “immunity level”. 20
volts/meter is a generally achievable and useful
immunity level against interference from radio
wave sources (the higher the immunity level, the
greater protection).
Your scooter has been tested and found to meet
the required immunity level from Electromagnetic
Interference (20v/m): the recommended density of
interference from electromagnetic energy.
Warning!
Even with the immunity level of 20
volts/meter, certain precautions must be followed
to ensure your scooter/wheelchair
will not be
affected by outside electromagnetic sources.
• Do not operate devices such as CB radios or
mobile phones while the vehicle is switched
on.
• Avoid getting close to transmitter masts, such as
television and radio masts.
• Note you may experience interference when
close to ambulance or fire stations.
If your vehicle starts to operate by itself switch it off
and report this to your dealer.
