NOTICE

THE INFORMATION CONTAINED IN THIS DOCUMENT IS SUBJECT TO

CHANGE WITHOUT NOTICE.

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

Wheelchair users should not be transported in vehicles of any kind while in

wheelchairs. 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.

 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, the belt

MUST be replaced IMMEDIATELY.

 ACCESSORIES 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.

SIGNAL WORD MEANING

DANGER Danger indicates an imminently hazardous situation which,

if not avoided, will result in death or serious injury.

WARNING Warning indicates a potentially hazardous situation which, if

not avoided, could result in death or serious injury.

CAUTION

Caution indicates a potentially hazardous situation which, if

not avoided, may result in property damage or minor injury

or both.

SPECIAL NOTES

Pronto® M51™and M61™with SureStep® 6Part No 1125085

 WARNING CONTINUED

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

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.

SECTION 2—EMI INFORMATION

Pronto® M51™and M61™with SureStep® 14 Part No 1125085

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 elec-

tric shavers and hair dryers, so far as we know, are not likely to cause EMI problems to

your powered wheelchair.

SECTION 2—EMI INFORMATION

Part No 1125085 15 Pronto® M51™and M61™with SureStep®

 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.

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.

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

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.

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.

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, cen-

ter 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.

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.
