8. EMC statements

This portion of the content will provide the user with basic information that describes the

problems with EMI, known sources of EMI, protective measures either to lessen the

possibility or exposure or to minimize the degree of exposure, and suggested action should

unexpected or erratic movement occur.

Caution: It is very important that you read this information regarding the possible

effects of electromagnetic interference on your electric

■ ELECTROMAGNETIC INTERFERENCE (EMI) FROM RADIO WAVE

SOURCES

Powered vehicle may be susceptible to electromagnetic interference (EMI), which is

interfering electromagnetic energy (EM) emitted from sources such as radio stations, TV

stations, amateur radio (HAM) transmitters, two-way radios, and cellular phones. The

interference (from radio wave sources) can cause the powered vehicle to release its brakes,

move by itself, or move in unintended directions. It can also permanently damage the

powered vehicle's control system. The intensity of the interfering EM energy can be

measured in volts per meter (V/m). Each powered vehicle can resist EMI up to a certain

intensity. This is called its "immunity level". The higher the immunity level the greater the

protection. At this time, current technology is capable of achieving at least a 20 V/m

immunity level, which would provide useful protection from the more common sources of

radiated EMI. This powered vehicle model as shipped, with no further modification, has an

immunity level of 20 V/m without any accessories.

There are a number of sources of relatively intense electromagnetic fields in the everyday

environment. Some of these sources are obvious and easy to avoid. Others are not apparent

and exposure is unavoidable. However, we believe that by following the warning listed

below, your risk to EMI will be minimized.
