Powered Chair Electromagnetic Interference (EMI) 
 
Because EMI energy rapidly becomes more intense as one moves 
closer to the transmitting antenna (source), the EMI fields from hand-
held radio sources (transceivers) are of special concern.  It is 
possible to unintentionally bring high levels of EMI energy very close 
to the power chair’s control system while using these devices.  This 
can affect powered chair movement and braking.  Therefore, the 
warnings listed below are recommended to prevent possible 
interference with the control system of the powered chair. 
 
WARNINGS 
 
The following warnings listed below should reduce the chance of 
unintended brake release or power chair movement, which could 
result in serious injury. 
 

1.  Do not operate hand-held transceivers (transmitter-receivers), 

such as citizens band (CB) radios, or turn ON personal 
communication devices, such as cellular phones, while the 
power chair 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 

power chair OFF as soon as it is safe. 

 

4.  Be aware that adding accessories or components, or modifying 

the power chair may make it more susceptible to EMI.   

 

 
Report all incidents of unintended movement or brake to the power 
chair provider, and note whether there are sources of EMI nearby.
