Power Wheel Chair Electromagnetic Interference
Since EM energy rapidly becomes more intense as one moves closer to the transmitting antenna (source), the
EM fields from hand-held radio wave sources (transceivers) are of special concern. It is possible to unintentionally
bring high levels of EM energy very close to a powered wheelchair’s control system while using these devices.
This can affect powered wheelchair movement and braking. Therefore, the warnings that follow are
recommended to prevent possible interference with the control system of the powered wheelchair.
EMI Warnings
Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur radio (HAM)
transmitters, two-way radios, and cellular telephones can affect powered wheelchairs. Following the warnings
listed below should reduce the chance of unintended brake release or powered wheelchair movement that could
result in serious injury.
Important Information.
1. Twenty (20) volts per meter (V/m) is a generally achievable and useful immunity level against EMI (the
higher the level the greater the protection).
2. The immunity level of this product is 20 V/m.
