Part No. 1123839 15
SECTION 2—EMI INFORMATION
SECTION 2—EMI INFORMATION
WARNING
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 powered 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 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).
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.
NOTE: Other types of hand-held 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 wheelchair.
16 Part No. 1123839
SECTION 2—EMI INFORMATION
WARNING
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 below 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).
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 metre (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) This device has been tested to a radiated immunity level of 20 volts per meter.
3) The immunity level of the product is unknown.
Modification of any kind to the electronics of this wheelchair as manufactured by
Invacare may adversely affect the EMI immunity levels.
Part No. 1123839 17
SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS
SECTION 3—SAFETY/HANDLING OF
WHEELCHAIRS
“Safety and Handling” of the wheelchair requires the close attention of the wheelchair
user as well as the assistant. This manual points out the most common procedures and
techniques involved in the safe operation and maintenance of the 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 wheelchair users often develop skills to deal with daily living activities that
may differ from those described in this manual. ProBasics 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 the new wheelchair user
and assistant with “safety” as the most important consideration for all.
Stability and Balance
WARNING
ALWAYS wear your seat positioning strap.The seat positioning strap is a
positioning belt only. It is not designed for use as a safety device withstanding high
stress loads such as auto or aircraft safety belts. If signs of wear appear, belt MUST
be replaced immediately.
To assure stability and proper operation of your wheelchair, you must at all times
maintain proper balance. Your 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 wheelchair any further than the length of the
armrests.
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.
While the walking beam allows you to traverse up to a 2-inch bump or threshold,
stopping after the wheels cross the bump poses a problem. The chair cannot reverse over
the bump at this point. Continue forward and then turn around.
While the wheelchair is designed for use primarily in and around the home, the provider
should determine whether this chair is suitable for the actual environment the chair will
be used in.

SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS
DO NOT go down ramp at full speed. Some seat/back positions will cause wheelchair to
feel unstable.
CAUTION
Be aware of condition of ramp. Traction will be diminished/nonexistent on a
slippery surface. Proceed with caution.
A Note to Wheelchair Assistants
When assistance to the wheelchair user is required, remember to use good body
mechanics. Keep your back straight and bend your knees whenever tilting wheelchair or
traversing curbs or other impediments.
Also, be aware of detachable parts such as arms or legrests. These must NEVER be used
to move the wheelchair or as 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.
Tipping
WARNING
DO NOT tip the wheelchair without assistance.
When tipping the wheelchair, an assistant should grasp the back of the wheelchair on a
non-removable (non-detachable) part. Inform the wheelchair occupant before tipping the
wheelchair and remind him/her to lean back. Be sure the occupant’s feet and hands are
clear of all wheels.
Tipping - Curbs
After mastering the techniques of tipping the wheelchair, use this procedure to tackle
curbs, short stairs, etc.
This procedure requires two assistants. The second assistant should be positioned at the
front of the wheelchair lifting upward on a non-removable (non-detachable) part of the
wheelchair frame when lifting the wheelchair and stabilizing the wheelchair when the
wheelchair is being lowered to the ground.
The first assistant should turn the anti-tippers so the wheels are pointing up, apply a
continuous downward motion until the balance point is achieved and the front casters
clear the curb. At this point, the assistants will feel a difference in the weight distribution.

SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS
WARNING
DO NOT let the wheelchair drop the last few inches to the ground. This could result
in injury to the occupant.
Roll the wheelchair forward and SLOWLY lower the wheelchair in one continuous
movement. Push the wheelchair forward until the rear wheels roll up and over the curb.
WARNING
Make sure anti-tipper wheels are pointing down towards the ground/floor before
using the wheelchair.
Turn the anti-tipper wheels down towards the ground/floor.
Lifting/Stairways
WARNING
DO NOT attempt to move an occupied power wheelchair between floors using a
stairway. Use an elevator to move an occupied power wheelchair between floors. If
moving a power wheelchair between floors by means of a stairway, the occupant
MUST be removed and transported independently of the power wheelchair.
Extreme caution is advised when it is necessary to move an unoccupied power
wheelchair up or down the stairs. ProBasics recommends using two assistants and
making thorough preparations.
Use ONLY secure, nondetachable parts for hand-hold supports.
It is strongly recommended to lift the wheelchair only by the rear frame and the
front forks - otherwise injury or damage may occur.
DO NOT attempt to lift the wheelchair by any removable (detachable) parts.
Lifting by means of any removable (detachable) parts of a wheelchair may result in
injury to the user or damage to the wheelchair.
The weight of the wheelchair without the user and batteries is between 80 and 127
lbs.
Follow this procedure for moving the wheelchair between floors when an elevator is NOT
available or lifting the wheelchair is necessary:
NOTE: When using a stairway to move the wheelchair, seat and any accessories, move all
wheelchair components away from the stairway prior to reassembly.
1. Remove the occupant from the wheelchair.
2. Remove the battery boxes from the wheelchair. Refer to Removing/Installing the
Battery Boxes on page 49.
3. If necessary, fold the wheelchair. Refer to Transporting the Wheelchair
4. Bend your knees and keep your back straight.
