F. IMMUNITY LEVEL
The level of EM energy is measured in volts per meter (V/m). Every power seating system
can resist EMI up to a certain level. This is called its “immunity level”.
The higher the immunity level, the less the risk of EMI. It is believed that a 20 V/m immu-
nity level will protect the power seating system user from the more common sources of
radio waves.
The configuration tested and found to be immune to at least 20 V/m is: Quickie S-626
power seating system with a right hand mounted QTRONIX remote joystick system, 20" seat
width, 18" seat depth, dual-post height adjustable armrests, elevating legrests and GP 24
gel cell batteries.
The following specialty input devices were not tested with the above listed power chair
configuration; therefore, their immunity level is unknown. These items include:
•
Breath Control
• Ribbon Switch
•
Heavy Duty Switched Joystick
• Disc Switch
•
Proportional Head Control
• Buddy Button
•
Wafer Board
• Micro Light
•
Tri-Switch Head Array
• Star Board
•
Proportional Mini-Joystick/Chin Control
• Penta Switch
•
Proximity Head Array
• Plate Switch
•
Zero Touch Switch
• Soft Switch
•
4-Zero Touch Switch
• Grasp Switch
•
5-Zero Touch Switch
• Wobble Switch
•
Treadle Switch
• 5-Switch Toggle
Individuals with physical limitations requiring the use of a specialty control input device
known not to be immune to 20 V/m, or not known, should exercise extra care around
known sources of EMI.
There is no way to know the effect on EMI if you add accessories or modify this seating
system.
Any change to your seating system may increase the risk of EMI. Parts from other suppliers
have unknown EMI properties.
G. REPORT ALL SUSPECTED EMI INCIDENTS
You should promptly report any unintended movement or brake release. Be sure to indicate
whether there was a radio wave source near your seating system at the time.
