Powered Vehicle Electromagnetic Interference (EMI)
Because EM energy rapidly becomes more intense as one moves
closer to the transmitting antenna, the EM field from hand-held radio
wave sources (transceivers) are of special concern. It is possible to
unintentionally bring high levels of EM energy close to the powered
vehicle’s control system while using these devices. This can affect powered vehicle
movement and braking.
Therefore, the warnings listed below are recommended to prevent possible
interference with the control system of the powered vehicle.
WARNINGS
Electromagnetic interference (EMI) from sources such as radio and TV stations,
amateur radio (HAM) transmitters, two-way radios and cellular phones can affect
powered vehicles.
Following the warnings listed below should reduce the chance of unintended brake
release or powered vehicle movement which could result in serious injury:
1) Do not operate hand-held transceivers (transmitters-receivers) such as citizen
band (CB) radios, or turn ON personal communication devices such as cellular
phones, while the powered vehicle is ON;
2) Be aware of nearby transmitters, such as radio or TV stations and try to avoid
coming close to them.
3) On appearance of unintended movements or brake release occurrences, switch
the powered vehicle OFF as soon as it is safe.
4) Be aware that adding accessories or components, or modifying the powered
vehicle, may make it more susceptible to EMI (Note: there is no easy way to
evaluate their effect on the overall immunity level of the powered vehicle).
5) Please report to us all incidents of unintended movement or brake release and
note whether there is a source of EMI nearby.
Important information
1) 20 volts per meter (V/m) is a generally achievable and useful immunity level
against EMI (as of May 1994). The higher the level the greater the protection;
2) This product delivered to you, has an immunity level of 20 V/m.
