ELECTROMAGNETIC INTERFERENCE (EMI) FROM RADIO WAVE SOURCES

Medical Power Wheelchairs (Hereinafter referred to as “Powerchair”) may be

susceptible to electromagnetic interference (EMI), which is a kind of interfering

electromagnetic energy (EM) emitted from sources such as radio stations, TV

stations, amateur radio (HAM) transmitters, two-way radio, and cellular phones. The

interference (from radio wave sources) can cause the Powerchair to release its brakes,

move by itself, or move in unintended directions. This can also permanently damage the

Powerchair’s control system.

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.

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  problems  to  the  Powerchair.
