GENERAL GUIDELINES GENERAL GUIDELINES SECTION 1 ELECTROMAGNETIC INTERFERENCE (EMI) 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, 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, 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.

ELECTROMAGNETIC INTERFERENCE (EMI)
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, 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, cassette players, and small
appliances, such as electric shavers and hair dryers, so far as we know, are not
