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. Invacare highly

recommends working with a certified rehab technology supplier and/or a member

of NRRTS or RESNA.

WHEELCHAIR TIE-DOWN RESTRAINTS AND SEAT RESTRAINTS (TRBKTS)

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.

 TRBKTS WARNINGS

Only use the transport brackets included with TRBKTS for the purposes described

in this manual.

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,

SPECIAL NOTES

Formula™CG Powered Seating 8 Part No 1143155

 WARNING

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.

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.

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.

Refer to wheelchair base owner’s manual for additional safety and operation

information.

 POWERED SEATING SYSTEM WARNINGS

This seating system has been custom 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.

Systems with TDX SP Bases Only - A pinch point exists between head tube cap and

walking beam.

Systems with TDX SP Bases Only - A pinch point exists between walking beam/

head tube cap and telescoping tube when the seat is in the lowest seat to floor

height.

Pinch point may occur when returning the tilted seat to the full upright position or

when lowering the elevating seat. Make sure the hands and body of the occupant,

attendants and bystanders are clear of all pinch points before lowering seat or

returning the tilted seat to the full upright position.

SECTION 3—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 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 elec-

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

your powered wheelchair.

 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 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.
