Invacare Xterra GT Operating And Maintenance Manual page 17

GENERAL GUIDELINES
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 wheelchair, may make it more susceptible to EMI (Note:
There is no easy way to evaluate their effect on the overall immunity
of the powered wheelchair); and
5) Report all incidents of unintended movement or brake release to the
powered wheelchair manufacturer, and note whether there is a source
of EMI nearby.
Important Information
1) 20 volts per meter (V/m) is a generally achievable and useful immunity
level against EMI (as of May 1994) (the higher the level, the greater the
protection);
2) The MCC MKIVcontroller for this application has an unknown
immunity level.
Modification of any kind to the electronics of this wheelchair as
manufactured by Invacare may adversely affect the RFI immunity levels.
