Heartway Medical Products S16 User Manual page 8

The FDA has written to the manufacturers of power scooters 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 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 scooter has an immunity level of 20 V/m which should protect against
common sources of EMI. Warning: The scooter itself can disturb the performance of the
electromagnetic fields such as emitted by alarm systems of shops.
