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
Electro-magnetic 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 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 configuration tested and found to be immune to at least
20 V/m is: Quickie Pulse power wheelchair with a right-hand
mounted RNET remote joystick system, 18" seat width, 18"
seat depth, dual post height adjustable armrests, fixed
tapered legrests with a two piece footplate, and Gp 22 gel
cell batteries.
4. All After Market input device options, classified as breath con-
trols, Proportional controls, and/or Switched controls that can
be used with this powerchair, have an unknown effect on their
immunity level to different types of EMI. They have not been
specifically tested with the Pulse 5/6 and RNET control system.
Individuals with physical limitations requiring the use of a specialty
control input device known not to be immune to 20V/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 not specifically tested or 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. Contact:
Sunrise Medical, Customer Service Department at (800) 333-4000.
G. EMI FROM CHAIR
The chair itself can disturb the performance of electromagnetic
fields such as emitted by alarm systems of shops.
H. HEAD ARRAY SAFETY AND RFI
If you have a Head-array, the sensors used in the product have the
potential to operate unintentionally if moisture or any substance
that is electrically conductive is present in sufficient quantities.
Electro magnetic interference from electrical power lines and cer-
tain types of phones can cause the sensors to activate.
These sensors are capacitive in nature, and can generate an elec-
tronic field, which can be affected by liquids and/or a source of
radio frequency Interferance (RFI). Any material that is conductive
has the potential to activate the Head-array unintentionally.
Avoid use under high power lines and around cell phones.
Avoid the use of a Head Array in rain or snow and protect against
the potential of spilled liquids on the sensors.
Avoid cell phones and electronic devices in proximity to the array.
Avoid any source that has the potential of (RFI).
Warn the user of this chair that the chair controls have the poten-
tial of acting erractically or making sudden stops, if (RFI) is not
avoided.
If any (RFI) causes erratic behavior, immediately cut off the power
to the wheelchair, and wait until the interference passes.
