This portion of the owner manual will provide the user with basic information about the
problems with EMI, known sources of EMI, protective measures either to lessen the
possibility of exposure, or to minimize the degree of exposure. This section also shows
situations where unexpected or erratic movements may occur.
Caution
: It is very important that you read this information regarding the possible
effects of electromagnetic interference on your electric Bladez B*Mobile vehicle.

ELECTROMAGNETIC INTERFERENCE (EMI) FROM RADIO WAVE
SOURCES
Powered vehicles 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 an electric powered vehicle to
release its brakes, move by itself, or move in unintended directions. It can also
permanently damage the electric powered vehicle’s control system. The intensity of
the interfering EM energy can be measured in volts per meter (V/m). Each electric
powered vehicle can resist EMI up to a certain intensity. This is called its “immunity
level”. The higher the immunity level is, the greater the protection is. 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 electric
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 our
everyday environment. Some of these sources are obvious and easy to avoid. Others
are not as apparent and exposure is unavoidable. However, we believe that by
following the warnings listed below, your risk to EMI will be minimized.
The sources of radiated EMI can be broadly classified into three types:
1. Hand-held portable transceivers (transmitter-receivers) with the antenna mounted
directly on the transmitting unit. Examples include: citizens band (CB) radios,
walkie talkies, security, fire, and police transceivers, cellular telephones and other
personal communication devices.
NOTE:
Some cellular telephones and similar devices transmit signals while they are
ON, even when not being used.
2.
Medium-range Mobile transceivers, such as those used in police cars, fire trucks,
ambulances and taxis. These usually have the antenna mounted on the outside of
the vehicle.
