USER DEVICE MAINTENANCE

SAFETY INFORMATIONSAFETY INFORMATION

1. Any setup, adjustment, or service not covered in this manual should be performed by a qualified service technician only. Service work performed by non-authorized personnel will void all warranties.

2. Contact your local service center or Position Dynamics directly if there are any questions on the operation of the seating system.

3. Inspect the seating system before each use. Do not use the seating system if any parts are missing, broken or are not operating properly. For assistance contact your local dealer or Position Dynamics customer service at 1-800-695-0081.

4. Do not exceed the guidelines for use indicated in this manual.

5. Do not shift your weight outside the frame of the seating system such as to reach

forward or to either side to pick up an object from the floor. This may cause the seating system on the power base to tip over and may cause personal or property damage.

6. Do not stand on any part of the seating system.

7. Do not lift or move the seating system using adjustable or removable parts, such as armrests or leg rests. This may cause personal or property damage.

8. Use caution when transferring the user into and out of the seating system .

9. To avoid damage and prevent injury, avoid activating the tilt and/or recline function near walls, furniture or other obstacles. Be sure other people are clear of the seating system before operation.

10. When driving the power base it is recommended the system be in the neutral position. Driving with the Optima™ seating system at a tilt and/or recline of 5º or greater may result in damage to the system.

11. Do not change or modify tilt or recline settings as it may increase the risk of a fall or tip-over.

12. This product may be equipped with a position belt (optional) that is only intended for mild restraint. It is not designed to withstand high stress loads.

13. Do not sit in this seating system while in a moving vehicle. Move to an approved vehicle seat. While seating system is transported, make certain it is stable and secure so that it cannot roll or shift.

14. Do not expose the Optima™ seating system to water. Should the Optima™ seating system come into contact with water, the following steps must be performed to ensure your seating system remains safe and reliable:

• Using a soft, dry towel, remove as much as the water as possible.

• Allow for the Optima™ seating system to dry overnight, allowing time for the remaining moisture to evaporate.

• Verify that your seating system functions normally before returning your seating system to service.

• Should the Optima™ seating system not function normally, contact your local service center.

15. Do not expose your Optima seating system to extreme temperatures. Keep the seating system in an environment with an ambient temperature between 18º F and 122º F. Failure to do so will result in a reduction of normal electrical and mechanical efficiency, and may shorten the life of the seating system.

16. Keep body parts, clothing and personal effects clear of the seating system’s moving components.

ELECTROMAGNETIC INTERFERENCE

CAUTION:

IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION REGARDING THE POSSIBLE

EFFECTS OF ELECTROMAGNETIC INTERFERENCE

Powered wheelchairs and motorized scooters (in this text, both will be referred to as powered wheelchairs) may be susceptible to electromagnetic interference (EMI) 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 EMI 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 protection.

At this time, current technology is capable of achieving at least a 20V/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 are obvious and easy to avoid. Others are not apparent and exposure is unavoidable. However, we believe that by following the warnings listed on page 10 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 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.

3. Long-range transmitters and transceivers, such as commercial broad- cast 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, and cassette players, and small appliances, such as electric shavers and hair dryers, as far as we know, are not likely to cause EMI problems to your powered wheelchair.

™

ELECTROMAGNETIC INTERFERENCE

ELECTROMAGNETIC INTERFERENCEELECTROMAGNETIC INTERFERENCE

POWERED WHEELCHAIR ELECTROMAGNETIC INTERFERENCE (EMI)

Because EMI energy rapidly becomes more intense as one moves closer to the transmitting antenna (source), the EMI fields from hand-held radio wave sources (transceivers) are of special concern. It is possible to unintentionally bring high levels of EMI 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 on page 10 are recommended to prevent possible interference with the control system of the powered wheelchair.

WARNINGS

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 citizen 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.

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

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).
