The FDA has written to the manufacturers of power wheelchairs asking them to test new
products to be sure they provide a reasonable degree of immunity against EMI. The FDA
requires that a powered wheelchair should have an immunity level of at least 20 V/m,
which provides a reasonable degree of protection against more common sources of
EMI. The higher the immunity level, the greater the protection.
Your powered wheelchair has an immunity level of 20 V/m which should protect against
common sources of EMI.
Environmental conditions may affect the safety and performance of your power
wheelchair. Water and extreme temperatures are the main elements that can cause
damage and affect performance.
A) Rain, Sleet and Snow
If exposed to water, your power wheelchair is susceptible to damage to electronic or
mechanical components. Water can cause electronic malfunction or promote
premature corrosion of electrical components and frame.
B) Temperature
Some of the parts of the power wheelchair are susceptible to change in temperature.
The controller can only operate in temperatures that range between 18 °F (-8 °C) and
122 °F (50 °C).
At extreme low temperatures, the batteries may freeze, and your power wheelchair
may not be able to operate. In extreme high temperatures, it may operate at slower
speeds due to a safety feature of the controller that prevents damage to the motors
and other electrical components.
