2.Medium-Range Mobile Transceivers:

These include two-way radios used in police cars, fire trucks, ambulances and taxi cabs.The antenna is usually mounted on the outside of the vehicle.

3.Long-Range Transceivers:

These include commercial radio and TV broadcast antenna towers and amateur (HAM) radios. Note: The following are not likely to cause EMI problems:

Lap-top computers (without phone or fax), Cordless phones,TV sets or AM/FM radios, CD or tape players.

D. DISTANCE FROM THE SOURCE

EM energy rapidly becomes more intense as you get closer to the source. For this reason, EMI from hand-held devices is of special concern.

(See C.1 above) A person using one of these devices can bring high levels of EM energy very close to your chair without you knowing it.

E. IMMUNITY LEVEL

1.The level of EM energy is measured in volts per meter (V/m). Every power wheelchair can resist EMI up to a certain level.This is called its “immunity level”.

2.The higher the immunity level, the less the risk of EMI. It is believed that a

20 V/m immunity level will protect the power wheelchair user from the more common sources of radio waves.

3.The configurations tested and found to be immune to at least 20 V/m are: Quickie S-525 power wheelchair with a right-hand mounted Penny & Giles Pilot integral controller, 16” seat width, 16” seat depth, single-post height adjustable armrest, swing-away hanger and U1 gel cell batteries.

Quickie S-525 power wheelchair with a right hand mounted QTRONIX remote joystick system, 16” seat width, 16” seat depth, single-post height adjustable arm- rests, swing-away hangers and U1 gel cell batteries.

4.a) Specialty input devices tested with the S-525 and QTRONIX controller that were found to be immune to 20 V/m include:

•Breath Control

•Heavy Duty Switched Joystick

•Proportional Head Control

•Wafer Board

b)Specialty input devices tested with the S-525 and QTRONIX controller that were found NOT to be immune to 20 V/m include:

•Tri-Switch Head Array

•Proportional Mini-Joystick/Chin Control

•Proximity Head Array

•Zero Touch Switch

V . E M I ( E L E C T R O M A G N E T I C I N T E R F E R E N C E )

•4-Zero Touch Switch

•5-Zero Touch Switch

c)Specialty input devices with an unknown immunity level because the devices were not tested with the S-525 and QTRONIX controller include:

•Treadle Switch

•Ribbon Switch

•Disc Switch

•Buddy Button

•Micro Light

•Star Board

•Penta Switch

•Plate Switch

•Soft Switch

•Grasp Switch

•Wobble Switch

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 chair. Any change to your chair may increase the risk of EMI. Parts from other suppliers have unknown EMI properties.

F.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 chair at the time.
