NOTICE
As a manufacturer of wheelchairs, Invacare endeavors to supply a wide variety of
wheelchairs to meet many needs of the 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 19.5.3 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 19.5.3. 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 94 for more information about
transporting the wheelchair.
TRRO AND TRBKTS WARNINGS

SPECIAL NOTES
WARNING
Always wear your positioning belt. If signs of wear appear, belt must be replaced
immediately.
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 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 chair 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

Pronto® M71™Jr. with SureStep
®
14 Part No 1122147
SECTION 1—GENERAL GUIDELINES
Charging Batteries
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.
Part No 1122147 15 Pronto® M71™Jr. with SureStep
®
SECTION 1—GENERAL GUIDELINES
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.
Rain Test
Invacare has tested its power wheelchairs in accordance with ISO 7176 “Rain Test.” This
provides the end user or his/her assistant sufficient time to remove his/her power
wheelchair from a rain storm and retain wheelchair operation.
DO NOT leave power wheelchair in a rain storm of any kind.
DO NOT use power wheelchair in a shower.
DO NOT store power wheelchair in a damp area for an extended period of time.
Direct exposure to excessive rain or dampness may cause the chair to malfunction
electrically and mechanically, may cause the chair to prematurely rust or may damage the
upholstery.
Check to ensure that the RED and GREY battery terminal caps are secured in place,
joystick boot is not torn or cracked where water can enter and that all electrical
connections are secure at all times.
DO NOT use the wheelchair if the joystick boot is torn or cracked. If the joystick boot
becomes torn or cracked, replace IMMEDIATELY.
Weight Training
Invacare DOES NOT recommend the use of its wheelchairs as a weight training
apparatus. Invacare wheelchairs have not been designed or tested as a seat for any kind
of weight training. If occupant uses said wheelchair as a weight training apparatus,
Invacare shall not be liable for bodily injury and the warranty is void.
Weight Limitation
The Pronto M71 jr. has a weight limitation of 150 lbs.

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.

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); 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) 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.

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. 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, seat positioning strap
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.
Be aware that carrying heavy objects on your lap while occupying the wheelchair
may adversely affect the stability of the wheelchair, resulting in serious bodily injury
to the user, damage to the wheelchair and surrounding property.
This wheelchair has been designed to accommodate one individual. If more than
one individual occupies the wheelchair this may adversely affect the stability of the
wheelchair, resulting in serious bodily injury to the user and passenger and damage
to the wheelchair and surrounding property.
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.
Part No 1122147 19 Pronto® M71™Jr. with SureStep
®
SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS
Coping With Everyday Obstacles
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 user to reach, bend and transfer in and out of
the wheelchair. These movements will cause a change to the 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 healthcare
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 casters as a tool to maintain stability and
balance.
The Pronto M71 jr. with SureStep has a weight limitation of 150 lbs.
DO NOT adjust the rear seat posts higher that the front seat posts.
NOTE: For this information, refer to FIGURE 3.1.
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 chair cannot reverse over the
bump at this point. Continue forward and
then turn around.
FIGURE 3.1 Coping With Everyday
2-inch Bump or Threshold
Obstacles
While the Pronto M71 jr. 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.
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.

SECTION 3—SAFETY/HANDLING OF WHEELCHAIRS
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.
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. Invacare 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 with batteries and without the user is between 203
and 318 lbs. Use proper lifting techniques (lift with your legs) to avoid injury.
