WARNING
●As a manufacturer of powered wheelchairs, KARMA endeavors to supply
a wide variety of powered wheelchairs to meet the many needs of the
user. However, the responsibility of final selection of the type of powered
wheelchair to be used by an individual rests solely with the user and
his/her healthcare professional capable of making such a selection.
●As of this date, this wheelchair has NOT been tested for safety in
collisions according to ISO-7176-19:2001. Therefore, this wheelchair
CANNOT be used as seats in any vehicles. That is, KARMA recommends
that users are NOT transported in any vehicle while seated in the
wheelchair. In the case of accident or a sudden stop, the user could be
thrown from the chair and get injured. The suggested solution is to move
the user from the wheelchair into a normal seat of the vehicle and to
securely stow the wheelchair in a separate compartment.
Operating Information
●Performance adjustments should ONLY be made by professionals of the
healthcare field or persons fully conversant with this process and the driver's
capabilities. Incorrect settings could cause injury to the driver or bystanders and
damage to the powered wheelchair and surrounding property.

professional.
●If so equipped, DO NOT operate the wheelchair without anti-tippers being
installed. Anti-tippers MUST BE attached at all times.
●DO NOT attempt to reach objects if you have to move forward in the seat or pick
them up from the floor by reaching down between your knees as this may cause
loss of balance.
●DO NOT lean over the back of the chair to reach objects behind you as this may
cause the powered wheelchair to tip over.
●DO NOT shift your weight or sitting position toward the direction you are reaching
as the powered wheelchair may tip over.
●DO NOT use an escalator to move a powered wheelchair between floors. Serious
bodily injury may occur.
●DO NOT operate in car lanes on roads, streets, highways, etc.
●DO NOT attempt to move up or down an incline with a water, ice or oil film.
●DO NOT attempt to ride over curbs or obstacles. Doing so may cause your
powered wheelchair to turn over and cause bodily harm and/or damage to the
powered wheelchair.
●DO NOT make sharp turns, in forward or reverse, at excessive speeds.
●DO NOT attempt to lift the powered wheelchair by its casings and seat.

3. EMI/RFI
This section provides the user with basic information about the problems with EMI,
known sources of EMI and protective measures either to reduce the possibility of
exposure or to minimize the degree of exposure. This section also shows some
conditions in which unexpected or erratic wheelchair movements may occur.
CAUTION
●It is very important that you read this information regarding the
possible effects of electromagnetic interference on your powered
KARMA wheelchair.
3.1 Electromagnetic Interference from Radio Wave Sources
3.1.1 Powered vehicles may be susceptible to electromagnetic interference
(EMI), which is interfering electromagnetic energy (EM) emitted from
sources such as radio stations (Radio Frequency Interference), TV stations,
amateur radio (HAM) transmitters, two-way radios, and cellular phones.
The interference (from radio wave sources) can cause the powered vehicle
to release its brakes, move by itself, or move in unintended directions. It
can also permanently damage the powered vehicle's control system. The
intensity of the interfering EM energy can be measured in volts per meter
(V/m). Each powered vehicle can resist EMI up to a certain intensity. This
amount of resistance 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. This powered
vehicle model, with no further modification, has an immunity level of 20
V/m without any accessories.
3.1.2 There are a number of sources of relatively intense electromagnetic fields
in our everyday environment. Some of these sources are obvious and easy
to avoid. Others are not apparent and exposure could be unavoidable.
However, we believe that by following the warnings listed below, your risk
to EMI can be greatly minimized.

8
3.2 The sources of radiatedEMI can be broadly classified into three
types.
3.2.1 Hand-held portable transceivers (transmitter-receivers) with the antenna
mounted directly on the transmitting unit, such as citizens band (CB) radios,
walkie-talkies, security and fire or police transceivers, cellular telephones
and other personal communication devices;
NOTE:
Some cellular telephones or similar devices transmit signals while they are ON, even
though they are not in use.
3.2.2 Medium-range mobile transceivers used in police cars, fire trucks,
ambulances and taxis usually having the antenna mounted on the outside
of the vehicle; and
3.2.3 Long-range transmitters and transceivers, such as commercial broadcast
transmitters (radio and TV broadcast antenna towers) and amateur (HAM)
radios.
NOTE:
Other types of hand-held devices (cordless phones, laptop computers, AM/FM
radios, TV sets, CD players, cassette players, and small appliances such as electric
shavers and hair dryers, et cetera) so far as we know, are not likely to cause EMI
problems.
3.3 Powered Vehicle ElectromagneticInterference (EMI)
Because EM energy rapidly becomes more intense as one moves closer to the
transmitting antenna (source), the EM fields from hand-held radio wave
sources (transceivers) are of special concern. It is possible to unintentionally
bring high levels of EM energy too close to the powered vehicle's control
system while using these devices. This can affect your powered vehicle's
movement and braking. Therefore, the warnings listed below are
recommended to prevent possible interference with the control system of the
powered vehicle.
