Electromagnetic Interference (EMI) from Radio Wave Sources
The Shuttle has been tested and is intended for safe use with other components compliant to IEC
601 standards for medical devices. The Shuttle may be susceptible to electromagnetic
interference (EMI), which is energy that is reflected or emitted from sources such as radio
stations, TV stations, amateur radio (HAM) transmitters, two-way radios and cellular phones in
the form of electrical and magnetic waves that travel through space. The interference (from
radio wave sources) is not likely but in extreme circumstances can cause this Shuttle to move by
itself or move in unintended directions. It can also permanently damage the Shuttle’s control
system. The intensity of the interfering EMI energy can be measured in volts per meter
(V/m). The Shuttle can resist EMI up to a certain intensity. This is called its “immunity level”.
