TDX® SP 18 Part No 1143209

SECTION 2—ELECTROMAGNETIC COMPATIBILITY (EMC) 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 metre (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 1143209 19 TDX® SP

SECTION 2—ELECTROMAGNETIC COMPATIBILITY (EMC) 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. Also, the electronics used in our powered wheelchair can generate a low level of electromagnetic interference, which however will remain within the tolerances permitted by law.

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 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.

 CAUTION

Risk of Injury or Damage EMC interference affecting other products may result in injury or damage. To avoid impacting the operation and function of other products:

- Products not specified by Invacare that may be used on or near the wheelchair may be

impacted by emissions from this product if they have a sensitivity level that is lower than the recognized standard and provided by this wheelchair. Refer to the manufacturer specifications for any electronic device BEFORE use near this product to determine its level of immunity and potential risk.

TDX® SP 20 Part No 1143209

SECTION 3—SAFETY INSPECTION/TROUBLESHOOTING

Safety Inspection Checklists

NOTE: Initial adjustments should be made to suit the end user's personal body structure needs and preference. After initial setup, perform these procedures every time the wheelchair is serviced.

Inspect/Adjust Initially

 DANGER

Risk of Injury, Damage or Death Overinflation of tires may cause tires to explode. —Inflate tire to the proper tire pressure (P.S.I./ kilopascals) listed on the side wall of the tire. —Only use wheelchair with tires at proper tire pressure. —The wheels and tires should be checked periodically for cracks and wear and should be

replaced if necessary.

❑ Ensure wheelchair rolls straight (no excessive drag or pull to one side). ❑ Inspect all fasteners. ❑ Inspect TRRO/TRBKTS fasteners and hardware. ❑ Ensure clothing guards are secure. ❑ Arms are secure but easy to release and adjustment levers engage properly. ❑ Adjustable height arms operate and lock securely. ❑ Upholstery has no rips. ❑ Armrest pad sits flush against arm tube. ❑ Axle nut and wheel mounting nuts are secure on drive wheels. ❑ No excessive side movement or binding when drive wheels are lifted and spun when disengaged (free-wheeling). ❑ Ensure that casters are free of debris. ❑ Wheels/casters have proper tension when wheels/casters are spun (when free-wheeling). Wheels/casters should come to a

gradual stop.

❑ Loosen/tighten caster locknut if wheel wobbles noticeably or binds to a stop. ❑ Ensure all caster/wheel/fork/headtube fasteners are secure and not damaged/missing. ❑ Wheel locks DO NOT interfere with tires when rolling. ❑ Wheel lock pivot point are free of wear and looseness. ❑ Wheel locks are easy to engage. ❑ Inspect tires for flat spots and wear. ❑ Check pneumatic tires for proper inflation. ❑ Check center mount front riggings for worn/frayed belts and/or loose fasteners. If found, replace these items.

❑ Check that all labels are present and legible. Replace if necessary.

❑ Inspect locking gas cylinders. ❑ Clean upholstery and armrests. ❑ Clean dirt and lint from axles. ❑ Clean dirt and lint from bearings. ❑ Inspect mechanical anti-dive for function. ❑ Inspect seat positioning strap for any signs of wear. Ensure buckle latches. Verify hardware that attaches strap to frame is

secure and undamaged. Replace if necessary.

❑ Inspect foam handgrips for damage. If damaged, have them replaced by a qualified technician. ❑ Inspect motor brushes and gearbox coupling. ❑ Inspect electrical components for signs of corrosion. Replace if corroded or damaged. ❑ For optimum performance, replace locking-gas cylinders every two years.
