WHEELCHAIR USER
As a manufacturer of wheelchairs, Invacare endeavors to supply a wide variety of
wheelchairs to meet many needs of the end user. However, final selection of the
type of wheelchair to be used by an individual rests solely with the user and his/her
healthcare professional capable of making such a selection.
WHEELCHAIR TIE-DOWN RESTRAINTS AND SEAT RESTRAINTS (TRRO OR
TRBKTS)
TRRO includes four factory-installed transport brackets and a wheelchair anchored
pelvic belt. TRRO has been crash-tested in accordance with ANSI/RESNA WC Vol 1
Section 19 Frontal Impact Test requirements for wheelchairs with a 168 lb crash
dummy, which corresponds to a person with a weight of 114 to 209 lbs.
TRBKTS includes four factory-installed wheelchair transport brackets. TRBKTS has
not been crash-tested in accordance with WC 19. Use these transport brackets only
to secure an unoccupied wheelchair during transport.
As of this date, the Department of Transportation has not approved any tie-down
systems for transportation of a user while in a wheelchair, in a moving vehicle of any
type. It is Invacare’s position that users of wheelchairs should be transferred into
appropriate seating in vehicles for transportation and use be made of the restraints
made available by the auto industry. Invacare cannot and does not recommend any
wheelchair transportation systems.
Refer to Transport Ready Package
on page 103 for more information about trans-
porting the wheelchair.
Part No 1141449 11 Pronto® M71™with SureStep

SPECIAL NOTES
TRRO AND TRBKTS WARNINGS
Only use the transport brackets included with TRRO and TRBKTS for the purposes
described in this manual.
WARNING
Invacare products are specifically designed and manufactured for use in conjunction
with Invacare accessories. Accessories designed by other manufacturers have not
been tested by Invacare and are not recommended for use with Invacare products.
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.
POWERED SEATING SYSTEMS ONLY - This seating system has been customer
designed and will be assembled to the wheelchair base before delivery to the user.
The information contained in this manual is for maintaining and adjusting the
seating system. There are very few adjustments that can safely be made by the user.
If there is a procedure or adjustment that needs to be performed on the seating
system that is not in this manual, DO NOT perform that procedure. Have the
seating system serviced by a qualified technician.
The drive behavior initially experienced by the user may be different from other
chairs previously used. This Power Wheelchair has Invacare’s SureStep technology,
a feature that provides the wheelchair with optimum traction and stability when
driving forward over transitions and thresholds of up to 2-inches. The following
warnings apply specifically to the SureStep Feature:
• DO NOT use on inclines greater than 9°.
• DO NOT use on inclines with wet, slippery, icy or oily surfaces. This may include
certain painted or otherwise treated wood surfaces.
• DO NOT traverse down ramps at high speed. Doing so will reduce traction and
increase stopping distance.
• The end user’s weight can materially affect traction on sloped surfaces. Great
care should be taken when traversing such slopes.
To determine and establish your particular safety limits, practice use of this product
on various sloping surfaces in the presence of a qualified healthcare provider
BEFORE attempting active use of this wheelchair. Other general warnings listed
within this document also apply.
Wheelchairs should be examined during maintenance for signs of corrosion (water
exposure, incontinence, etc.). Electrical components damaged by corrosion should
be replaced IMMEDIATELY.
Wheelchairs that are used by incontinent users and/or are frequently exposed to
water may require replacement of electrical components more frequently.

TYPICAL PRODUCT PARAMETERS
**NOTE: Values for range are calculated for maximum chair weight rating using largest batteries
applicable (U1), per test procedures described in ANSI/RESNA WC/VOL2-1998 Section 4 and
meet federal reimbursement requirements for this product. While considered typical, they are
derived based on certain ideal conditions. Variances in battery condition, user weight, usage
pattern or overall terrain conditions will result in actual values for range that differ from these
stated values. Users should become accustomed to how their unique conditions impact their
individual results. Users should become familiar with the battery discharge indicator on the
joystick to determine the range of their wheelchair. Refer to Battery Charger Operation on page 89
for more information about the battery discharge indicator.

*NOTE: The seat-to-floor height is based on 18-inch deep seat with 0° (±1°) seat pan angle and
pneumatic tires or flat free inserts. Seat-to-floor height measured from the front edge of seat to floor.
The height is measured with properly inflated new tires. This height can vary ±¼-inch due to tire
wear.
If the seating system is mounted onto a power wheelchair that has a weight limitation greater than that of the seating system, the weight limitation is maintained at
the seating system’s weight limitation. Example: The M71 Standard wheelchair has
a 300 lb weight limitation, the seating system has a weight limitation of 275 lbs, so
the M71 Standard wheelchair now has a 275 lb. weight limitation.

SECTION 8—GENERAL GUIDELINES
ALWAYS shift your weight in the direction you are turning. DO NOT shift your weight in
the opposite direction of the turn. Shifting your weight in the opposite direction of the
turn may cause the inside drive wheel to lose traction and the wheelchair to tip over.
DO NOT shift your weight or sitting position toward the direction you are reaching as the
wheelchair may tip over.
DO determine and establish your particular safety limits by practicing bending, reaching
and transferring activities in the presence of a qualified healthcare professional BEFORE
attempting active use of the wheelchair.
DO NOT attempt to reach objects if you have to move forward in the seat.
DO NOT attempt to reach objects if you have to pick them up from the floor by reaching
down between your knees.
DO NOT lean over the top of the back upholstery to reach objects behind you as this may
cause the wheelchair to tip over.
DO NOT store items under seat - interference with seat latch may result.
DO NOT use an escalator to move a wheelchair between floors. Serious bodily injury may
occur.
Before attempting to transfer in or out of the wheelchair, every precaution should be
taken to reduce the gap distance. Turn both casters parallel to the object you are
transferring onto. Also be certain the power is Off and wheel locks are engaged to prevent
the wheels from moving.
DO NOT engage or disengage the motor release levers until the power is in the Off

DANGER
When using an extension cord, use only a three wire extension cord having at least
16 AWG (American Wire Gauge) wire and the same or higher electrical rating as
the device being connected. Use of improper extension cord could result in risk of
fire and electric shock. Three prong to two prong adapters should not be used. Use
of three prong adapters can result in improper grounding and present a shock hazard to the user.
NEVER attempt to recharge the batteries by attaching cables directly to the battery terminals.
DO NOT attempt to recharge the batteries and operate the wheelchair at the same time.
DO NOT operate wheelchair with extension cord attached to the AC cable.
DO NOT attempt to recharge the batteries when the wheelchair has been exposed to ANY
type of moisture.
DO NOT attempt to recharge the batteries when the wheelchair is outside.
DO NOT sit in the wheelchair while charging the batteries.
DO NOT attempt to recharge batteries using BOTH the on-board battery charger AND an
independent battery charger (plugged into the joystick charger port) at the SAME time.
Doing so will reduce the life of the batteries.
Read and carefully follow the manufacturer’s instructions for each charger (supplied or
purchased). If charging instructions are not supplied, consult a qualified technician for
proper procedures.
After charging batteries, ALWAYS make sure that the battery charger cord is securely
wrapped and stored within the hook and loop strap assembly on the rear of the battery
tray. Failure to do so may result in damage to the cord or personal injury to the user or
bystanders.
Ensure the pins of the extension cord plug are the same number, size, and shape as those
on the charger.
DO NOT under any circumstances cut or remove the round grounding plug from the
charger AC cable plug or the extension cord plug.
Grounding Instructions
DO NOT, under any circumstances, cut or remove the round grounding prong from any
plug used with or for Invacare products. Some devices are equipped with three-prong
(grounding) plugs for protection against possible shock hazards and fire. Where a twoprong wall receptacle is encountered, it is the personal responsibility and obligation of the
customer to contact a qualified electrician and have the two-prong receptacle replaced with
a properly grounded three-prong wall receptacle in accordance with the National Electrical
Code. If you must use an extension cord, use ONLY a three-wire extension cord having the
same or higher electrical rating as the device being connected. In addition, Invacare has
placed RED/ORANGE warning tags on some equipment. DO NOT remove these tags.

SECTION 9—EMI INFORMATION
SECTION 9—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.
Part No 1141449 23 Pronto® M71™with SureStep
™
SECTION 9—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); 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 the product is unknown.
Modification of any kind to the electronics of this wheelchair as manufactured by
Invacare may adversely affect the RFI immunity levels.

SECTION 10—SAFETY/HANDLING OF WHEELCHAIRS
SECTION 10—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. 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 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
DO NOT climb, go up or down ramps or traverse slopes greater than 9°.
Invacare strongly recommends proceeding down ramps or slopes at half speed or
slower and to avoid hard braking or sudden stops.
DO NOT leave elevating legrests in the fully extended position when proceeding
down ramps or slopes.
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.

SECTION 10—SAFETY/HANDLING OF WHEELCHAIRS
Coping with Everyday Obstacles
NOTE: For this procedure, refer to
FIGURE 10.1.
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 to traverse
up to a 2-inch bump or threshold, stopping
after the wheels cross the bump poses a
problem. The wheelchair cannot reverse
over the bump at this point. Continue
forward and then turn around.
While the M71 is designed for use
primarily in and around the home, the
provider should determine whether this
wheelchair is suitable for the actual
environment the wheelchair will be used
in.
FIGURE 10.1 Coping with Everyday
2-inch Bump
or Threshold
Obstacles
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 tipping 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.
