3 Electromagnetic Compatibility (EMC)
Information
3.1 Electromagnetic Interference (EMI) From Radio
Frequency Sources
Powered wheelchairs and motorized scooters (in this text, both
will be referred to as mobility devices) may be susceptible to
electromagnetic interference (EMI), which is interfering
electromagnetic energy (EM) emitted from sources such as
radio stations, TV stations, amateur radio (HAM) transmitters,
two way radios, and cellular phones. The interference (from
radio wave sources) can cause the mobility devices to release
its brakes, move by itself, or move in unintended directions. It
can also permanently damage the mobility devices control
system. The intensity of the interfering EM energy can be
measured in volts per meter (V/m). Each powered mobility
device can resist EMI up to a certain intensity. This is called its
"immunity level." The higher the immunity level, the greater
the protection. At this time, current technology is capable of
achieving at least a 20 V/m immunity level, which would
provide useful protection from the more common sources of
radiated EMI.
There are a number of sources of relatively intense
electromagnetic fields in the everyday environment. Some of
these sources are obvious and easy to avoid. Others are not
apparent and exposure is unavoidable. However, we believe
that by following the warnings listed below, your risk to EMI will
be minimized.
The sources of radiated EMI can be broadly classified
into three types:
1. Hand-held Portable transceivers (transmitters/receivers
with the antenna mounted directly on the transmitting
unit. Examples include: citizens band (CB) radios, “walkie
talkie”, security, fire and police transceivers, cellular
telephones, and other personal communication devices).
Some cellular telephones and similar devices
transmit signals while they are ON, even when
not being used.
2. Medium-range mobile transceivers, such as those used in
police cars, fire trucks, ambulances and taxis. These usually
have the antenna mounted on the outside of the vehicle.
3. Long-range transmitters and transceivers, such as
commercial broadcast transmitters (radio and TV
broadcast antenna towers) and amateur (HAM) radios.
60101916-A 15
3 Electromagnetic Compatibility (EMC) Information

Other types of handheld devices, such as cordless
phones, laptop computers, AM/FM radios, TV sets, CD
players, cassette players, and small appliances, such as
electric shavers and hair dryers, so far as we know, are
not likely to cause EMI problems to your powered
mobility device.
3.2 Powered Wheelchair Electromagnetic
Interference (EMI)
Because EM energy rapidly becomes more intense as one
moves closer to the transmitting antenna (source), the EM fields
from handheld radio wave sources (transceivers) are of special
concern. It is possible to unintentionally bring high levels of EM
energy very close to the mobility devices control system while
using these devices. This can affect the mobility device’s
movement and braking. Therefore, the warnings listed below
are recommended to prevent possible interference with the
control system of the mobility device.
Electromagnetic interference (EMI) from sources such as radio
and TV stations, amateur radio (HAM) transmitters, two-way
radios, and cellular phones can affect powered wheelchairs and
motorized scooters.
FOLLOWING THE WARNINGS LISTED BELOW SHOULD
REDUCE THE CHANCE OF UNINTENDED BRAKE RELEASE
OR POWERED WHEELCHAIR MOVEMENT WHICH COULD
RESULT IN SERIOUS INJURY.
WARNING!
-DO NOT operate handheld transceivers (transmitters
receivers), such as citizens band (CB) radios, or turn
ON personal communication devices, such as cellular
phones, while the mobility device is turned ON;
-Be aware of nearby transmitters, such as radio or TV
stations, and try to avoid coming close to them;
-If unintended movement or brake release occurs,
turn the mobility device OFF as soon as it is safe;
-Be aware that adding accessories or components, or
modifying the mobility device, may make it more
susceptible to EMI (Note: There is no easy way to
evaluate their effect on the overall immunity of the
mobility device); and
-Report all incidents of unintended movement or
brake release to Invacare and note whether there is
a source of EMI nearby.
16 60101916-A
Invacare® AVIVA™ FX

WARNING!
Important Information
-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);
-This device has been tested to a radiated immunity
level of 20 volts per meter.
-The immunity level of the product is unknown.
-Modification of any kind to the electronics of this
mobility device as manufactured by Invacare may
adversely affect the EMI immunity levels.
3.3 Powered Wheelchair Electromagnetic
Emissions
CAUTION!
Risk of Injury or Damage
EMC interference affecting other products may result
in injury or damage.
To avoid impacting the operation and function of
other products:
-Products not specified by Invacare that may be used
on or near the mobility device may be impacted by
emissions from this product if they have a sensitivity
level that is lower than the recognized standard and
provided by this mobility device. Refer to the
manufacturer specifications for any electronic device
BEFORE use near this product to determine its level
of immunity and potential risk.

Interference may occur in the vicinity of equipment marked
with the following symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and landmobile radios,
amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured
field strength in the location in which the AVIVA FX Power Wheelchair is used exceeds the applicable RF compliance level above,
the AVIVA FX Power Wheelchair should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the AVIVA FX Power Wheelchair.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
Recommended separation distances between portable and mobile RF communications equipment and the AVIVA FX Power
Wheelchair
The AVIVA FX Power Wheelchair is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
