at least 16 AWG (American Wire Gauge) wire and the same or higher electrical rating as the device being connected.

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

WARNING

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 two-prong 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.

GENERAL GUIDELINES

Three (3) prong to two (2) prong adapters should not be used. Use of three (3) prong adapters can result in improper grounding and present a shock hazard to the user.

WEIGHT TRAINING

WARNING

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 OR PROPERTY DAMAGE AND THE WARRANTY IS VOID.

WEIGHT LIMITATION

WARNING

The Pronto M71 Jr. has a weight limitation of 150 lbs.

Part No. 1122147 11 Pronto® M71Jr.

with SureStep

SECTION 1

GENERAL GUIDELINES

RAIN TEST

WARNING

INVACARE has tested its power wheelchairs in accordance with ISO 7176 Part 9 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 wheel-

chair 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.

GENERAL GUIDELINES

DO NOT leave power wheelchair in a damp area for any length of time. Direct exposure to rain or dampness will 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 black 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 joystick if the boot is torn or cracked. If the joystick boot becomes torn or cracked, replace IMMEDIATELY.

ELECTROMAGNETIC INTERFERENCE (EMI)

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 should provide useful protection from the more common sources of radiated EMI.

GENERAL WARNINGS

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.

Pronto® M71 Jr. 12 Part No. 1122147 with SureStep

GENERAL GUIDELINES

SECTION 1

GENERAL WARNINGS (CONTINUED)

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 wheel chair.

GENERAL GUIDELINES

POWERED WHEELCHAIR ELECTROMAGNETIC INTERFERENCE (EMI)

GENERAL WARNINGS

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;

and is immune to signal levels up to 20 V/m, the maximum immunity level of the product is unknown.

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

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.

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.

Pronto® M71 Jr. 14 Part No. 1122147 with SureStep

GENERAL GUIDELINES

COPING WITH EVERYDAY OBSTACLES

SECTION 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 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 Pronto M71 Jr wheelchair is designed for use primarily in and around the home, the provider should determine whether the chair is suitable for the actual environment that the chair will be used.

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/non-existent on a slippery surface. Proceed with caution.

A NOTE TO WHEELCHAIR ASSISTANTS

GENERAL GUIDELINES

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 the footboard. 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.

STAIRWAYS

WARNINGS

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 (2) assistants and making thorough preparations. Disassemble wheelchair. Refer to TRANSPORTING in this manual.

Make sure to use ONLY secure, non-detachable parts for hand-hold supports. 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.

ESCALATORS

DO NOT use an escalator to move a wheelchair between floors. Serious bodily injury may occur.

TRANSFERRING TO AND FROM OTHER SEATS

ALWAYS turn the wheelchair power OFF and engage the Motor Release Levers to prevent the wheels from moving BEFORE attempting to transfer in or out of the wheelchair. Also, make sure every precaution is taken to reduce the gap distance by aligning both the front AND rear casters parallel with the object you are transferring onto.

TRANSPORTING THE WHEELCHAIR in SEC-

WARNING

CAUTION

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

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

MINIMIZE GAP

DISTANCE

1. Position the wheelchair as close as possible along side the seat to which you are transferring, with the front casters parallel to it.

2. After the wheelchair is positioned properly for transfer, verify that the Motor Release Levers are engaged. Refer to DISENGAGING MOTOR RELEASE LEVERS in SECTION 8 of this manual.

3. 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.

ENGAGING/

GENERAL GUIDELINES

PERCENTAGE OF WEIGHT DISTRIBUTION

SECTION 1

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 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 M71 Jr. has a weight limitation of 150 lbs. DO NOT adjust the rear seat posts higher that the front seat posts.

REACHING, LEANING AND BENDING - FORWARD

Position the front AND rear casters so that they are extended as far rearward as possible and engage Motor Release Levers.

GENERAL GUIDELINES

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.

REACHING AND BENDING - BACKWARD

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

SECTION 3

(FIGURE 1)

DRIVE 1/DRIVE 2/OFF SWITCH - Three (3) position toggle is located at the back of the joystick housing. This switch allows the operator to select the type of operation or performance which best suits a particular control need or situation. The DRIVE 1 program uses performance values which are independent of those used for the DRIVE 2 program. As an example, an operator may have a control need for spasticity in the morning and a very different need in the afternoon. DRIVE 1 can be programmed for higher speeds and quicker response while DRIVE 2 can be programmed for slower speeds and less responsiveness or vise versa.  To select DRIVE 1 mode, move the toggle UP.  To select DRIVE 2 mode, move the toggle to the MIDDLE position.

WHEELCHAIR OPERATION

SPEED CONTROL - Rotary knob is located at the back of the joystick housing. Turning the knob clockwise increases the maximum speed of the chair.

JOYSTICK - Control Knob, located on the top of the control, provides proportional drive control of speed and direction.

MODE(ON/OFF) SWITCH - Push button switch located at the front of the joystick can be used to control an optional actuator. Pushing the switch will change the controller mode to control the chairs actuator through the joystick. The mode switch LED indicator will be ON. Push the switch again to return to normal joystick driving. The mode switch LED indicator will be off.

BATTERY GAUGE DISPLAY (BGD) - Located at the rear of the

joystick housing, it provides information on the remaining charge in the batteries. At full charge all six (6) segments of the bar graph are lighted; as the battery becomes discharged the farthest right segment will go out until only the red bar is lighted; at this level the last red bar will start to flash on and off to indicate that the user should charge the batteries as soon as possible.

The BGD also serves as a system diagnostic device when a fault is detected by the control module. A specific number of flashes of the last two red bars (up to eight (8) flashes) will start to flash on and off to indicate the type of fault detected separated by a pause. A chart of the diagnostic indications is given in the DIAGNOSTIC CODE Section of the Electronics Manual, part number 1114808.
