approaches the source. All electrical conductors act as antennas to the EM 

signals  and,  to  varying  degrees,  all  power  wheelchairs  and  scooters  are 

susceptible  to  electromagnetic  interference(EMI).  The  interference  could 

result  in  abnormal,  unintentional  movement  and/or  erratic  control  of  the 

vehicle.  The  United  States  Food  and  drug  Administration  (FDA)  suggests 

that  the  following  statement  be  incorporated 

to  the  user’s  manual  for  all 

power wheelchairs like the P20CL 

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 

wheel- 

chair,  may  make  it  more  susceptible  to  interference  from  radio  wave 

sources.(Note: It is difficult to evaluate the effect on the overall immunity of 

the powered wheel- 

chair). 

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.  Power wheelchairs and motorized scooters (in this section, 

both will be referred to 

as powered wheelchairs) may as susceptible to electromagnetic interference 

(EMI),   

which  is  interfering  electromagnetic  energy  emitted  from  sources  such  as 

radio stations, TV stations, amateur radio (HAN) transmitter, 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  directions.  It  can  also  permanently  damage  the  powered 
wheelchair’s control system. The inten- 

sity  of  the  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 
“immunity level”.   

The  higher  the  immunity  level,  the  greater  the  protec

t

ion.  At  this  time, 

current technology is capable of providing at least 20 V/m of immunity level, 

which would provide useful protection against common sources of radiated 

EMI. 

Following the warnings listed below should reduce the chance of  unintended 

brake  release  or  powered  wheelchair  movement  that  could  result  in  serious
