CAUTION: IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION REGARDING THE POS­SIBLE EFFECTS OF ELECTROMAGNETIC INTERFERENCE ON YOUR POWERED WHEELCHAIR.

Electromagnetic Interference (EMI) From Radio Wave sources
Powered wheelchairs and motorized scooters (in this text, both will be referred to as pow-

ered wheelchairs) 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 powered wheelchair to release its brakes,
move by itself, or move in unintended directions. It can also permanently damage the
powered wheelchair's control system. The intensity of the interfering EM energy can be
measured in volts per meter (V/m). Each powered wheelchair 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 protec-

tion 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, 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. **NOTE: 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; and

3) Long-range transmitters and transceivers, such as commercial broadcast
transmitters (radio and TV broadcast antenna towers) and amateur (HAM) radios.

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 wheelchair.

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 hand-held radio wave sources (transceivers) are of
special concern. It is possible to unintentionally bring high levels of EM energy very close
to the powered wheelchair's control system while using these devices. This can affect pow­ered wheelchair movement and braking. Therefore, the warnings listed are recommended
to prevent possible interference with the control system of the powered wheelchair.

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.

1) Do not operate hand-held transceivers (transmitters receivers), such as citi­zens band (CB) radios, or turn ON personal communication devices, such
as cellular phones, while the powered wheelchair is turned ON;

2) Be aware of nearby transmitters, such as radio or TV stations, and try to
avoid coming close to them;

3) If unintended movement or brake release occurs, turn the powered wheel­chair OFF as soon as it is safe;

4) Be aware that adding accessories or components, or modifying the pow­ered wheelchair, may make it more susceptible to EMI (Note: There is no
easy way to evaluate their effect on the overall immunity of the powered
wheelchair); and

5) Report all incidents of unintended movement or brake release to the pow­ered wheelchair manufacturer, and note whether there is a source of EMI
nearby.

Important Information

1) 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);

2) The immunity level of this product is not known.

Modification of any kind to the electronics of this wheelchair as manufactured
by Invacare may adversely affect the RFI immunity levels.

GENERAL GUIDELINESPROCEDURE 1

SAFETY/HANDLING OF SEATING
SYSTEMS/WHEELCHAIRS

Safety and Handling of the wheelchair requires the close
attention of the seating system/wheelchair user as well
as the assistant. This manual, as well as the owners
manual provided with the wheelchair, points out the most
common procedures and techniques involved in the safe
operation and maintenance of the seating system/wheel­chair. It is important to practice and master these safe
techniques until you are comfortable in maneuvering
around the frequently encountered architectural barriers.

Use this information only as a basic guide. The tech­niques that are discussed on the following pages have
been used successfully by many.

Individual seating system/wheelchair users often develop
skills to deal with daily living activities that may differ from
those described in this manual. Invacare recognizes and
encourages each individual to try what works best for him/
her in overcoming architectural obstacles that they may
encounter, however, ALL WARNINGS and CAUTIONS
given in this manual MUST be followed. Techniques in
this manual are a starting point for new seating system/
wheelchair users and assistants with safety as the most
important consideration for all.

Also, be aware of any detachable parts. These must
NEVER be used for hand-hold or lifting supports, as they
may be inadvertently released, resulting in possible injury
to the user and/or assistant(s).

When learning a new assistance technique, have an ex­perienced assistant help you before attempting it alone.

Percentage of Weight Distribution

WARNING

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.

Many activities require the wheelchair owner to reach, bend
and transfer in and out of the wheelchair. These move­ments will cause a change to normal balance, center of
gravity, and weight distribution of the wheelchair. To deter­mine and establish your particular safety limits, practice
bending, reaching and transferring activities in several com­binations in the presence of a qualified health professional
BEFORE attempting active use of the wheelchair.

Proper positioning is essential for your safety. When reach­ing, leaning, bending or bending forward, it is important to
use the front casters as a tool to maintain stability and bal­ance.

Stability and Balance

WARNING

Always wear your seat positioning strap.

To assure stability and proper operation of your seating
system/wheelchair, you must at all times maintain proper
balance. Your seating system/wheelchair has been de­signed to remain upright and stable during normal daily
activities as long as you do not move beyond the center of
gravity.

DO NOT lean forward out of the seating system/wheel­chair any further than the length of the armrests. Make
sure the casters are pointing in the forward position when­ever you lean forward. This can be achieved by advanc­ing the wheelchair and then reversing it in a straight line.

Coping With Everyday Obstacles

Coping with the irritation of everyday obstacles can be
alleviated somewhat by learning how to manage your
wheelchair. Keep in mind your center of gravity to main­tain stability and balance.

A Note to Wheelchair Assistants

When assistance to the seating system/wheelchair user
is required, remember to use good body mechanics. Keep
your back straight and bend your knees.

BEFORE attempting to transfer in or out of
the wheelchair, every precaution should
be taken to reduce the gap distance. Turn
both casters toward the object you are
transferring onto. Also be certain to en­gage motor locks to help prevent the
wheels from moving.

When transferring, position yourself as far
back as possible in the seat. This will pre­vent broken screws, damaged upholstery
and the possibility of the wheelchair tip­ping forward.

NOTE: This activity may be performed independently pro­vided you have adequate mobility and upper body
strength.

Reaching, Bending - Backwards

WARNING

DO NOT lean over the top of the back
upholstery. This will change your center
of gravity and may cause you to tip over.

Position the wheelchair as close as possible along
side the seat to which you are transferring, with the
casters aligned parallel with the object. Engage
motor locks. Shift body weight into seat with transfer.

During independent transfer, little or no seat platform
will be beneath you. Use a transfer board if at all pos­sible.

Position wheelchair as close as possible to the de­sired object. Point front casters forward to create the
longest possible wheelbase. Reach back only as far
as your arm will extend without changing your sitting
position.
