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

Powerchair OFF as soon as it is safe. 

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

the Powerchair may make it more susceptible to EMI.   

 

 
Report all incidents of unintended movement or brake to your 
Powerchair provider, and note whether there are sources of EMI 
nearby. 
 
NOTE: The VSI controller EMI rating is FDA Regulated and 
conforms to federal regulations.
