Powered Wheelchair Electromagnetic Interferences (EMI)

Because 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 the powered wheelchair’s control system while using these devices. This can affect powered

wheelchair movement and braking. Therefore, the warnings listed below are recommended to prevent possible interference

with the control system of the powered wheelchair.

Radio wave sources may affect powered wheelchair control

Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur radio (HAM) transmitters, two-way

radios, and cellular phones can affect powered wheelchairs and motorized scooters. Following the warnings listed below

should reduce the chance of unintended brake release or powered wheelchair movement which could result in serious injury.

1) Do not operate hand-held transceivers (transmitters-receivers), such as citizens band (CB) radios, or turn ON personal

communication devices, such as cellular phones, radio frequency identification (RFID), while the powered wheelchair is

turned ON;

2) Be aware of nearby transmitters, such as radio or TV stations, and try to avoid coming close to them;

3) If unintended movement or brake release occurs, turn the powered wheelchair OFF as soon as it is safe;

4) Be aware that adding accessories or components, or modifying the powered wheelchair, may make it more susceptible to

interference from radio wave sources.

(Note: There is no easy way to evaluate their effect on the overall immunity of the powered wheelchair); and

5) Report all incidents of unintended movement or brake release to the powered wheelchair manufacturer, and note

whether there is a radio wave source nearby.

Important Information

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). All alber power-drives have an immunity level of 20 V/m.

IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION REGARDING THE POSSIBLE EFFECTS OF ELECTRO-MAGNETIC

INTERFERENCE ON YOUR POWERED WHEELCHAIR.

Electromagnetic Interference (EMI) From Radio Wave Sources

Powered wheelchairs and motorized scooters (in this text, both will be referred to as powered wheelchairs) may be suscep-

tible to electromagnetic interference (EMI), which is interfering electromagnetic energie (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 wheelchair to release its brakes, move by itself, or move in unintended direc-

tions. It can also permanently damage the powered wheelchair’s control system. The intensity of the interfering EM energy

can be measured in volts per meter (V/m). Each powered wheelchair can resist EMI up to a certain intensity. This is called

its “immunity level”. The higher the immunity level, the greater the protection.

There are a number of sources of relatively intense electromagnetic fields in the everyday environment. Some of these sour-

ces are obvious and easy to avoid. Others are not apparent and exposure is unavoidable. However, we believe that by fol-

lowing 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 (transmitters-receivers) with the antenna, mounted directly on the transmitting unit.

Examples include: citizens band (CB) radios, “walkie talkie”, security, fire and police transceivers, cellular telephones,

radio frequency identification (RFID), 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; and

3) Long-range transmitters and transceivers, such as commercial broadcast transmitters (radio and TV broadcast antenna

towers) and amateur (HAM) radios.

Note: Other types of hand-held devices, such as cordless phones, laptop computers, AM/FM radios, TV sets, CD players,

and cassette players, and small appliances, such as electric shavers and hair dryers, so far as we know, are not likely

to cause EMI problems to your powered wheelchair.
