A. CHOOSE THE RIGHT CHAIR & SAFETY OPTIONS

Sunrise provides a choice of many power wheelchair styles, sizes and adjustments to meet the needs of the rider. However, final selection of a wheelchair rests solely with you and your health care professional. Choosing the best chair for you depends on such things as:

1.Your size, disability, strength, balance and coordination.

2.Your intended use, and your level of activity.

3.The types of hazards you must overcome in daily use (in areas where you are likely to use your chair).

4.The need for options for your safety and comfort (such as position- ing belts or special seat systems).

B.ADJUST CHAIR TO YOUR ABILITY

You need to work with your doctor, nurse or therapist, and your supplier, to fit this chair and adjust the controller settings for your level of function and ability.

NOTE– Where they apply, you will also find “Warnings” in other sections of this Manual.

V. EMI (ELECTROMAGNETIC INTERFERENCE)

Heed all warnings to reduce the risk of unintended brake release or chair movement:

1.Beware of the danger from hand-held transceivers. (A “trans- ceiver” is a device that both sends and receives radio wave signals). Never turn on or use a hand-held transceiver while power to your chair is on. Use extra care if you believe that such a device may be in use near your chair.

2.Be aware of nearby radio or TV stations, and avoid coming close to them.

3.If unintended movement occurs, turn your chair off as soon as it is safe to do so.

B.WHAT EFFECT CAN EMI HAVE?

1.EMI can cause your chair, without warning, to:

• Release its brakes

• Move by itself

• Move in unintended directions

If any of these occurs, it could result in severe injury to you or others.

2.EMI can damage the control system of your chair. This could create a safety hazard, and lead to costly repairs.

C.SOURCES OF EMI

A. WHAT IS EMI?

1.EMI means: electromagnetic (EM) interference (I). EMI comes from radio wave sources such as radio transmitters and transceivers.

2.There are a number of sources of intense EMI in your daily environ- ment.

Some of these are obvious and easy to avoid. Others are not, and you may not be able to avoid them.

3.Powered wheelchairs may be susceptible to electromagnetic inter- ference (EMI) emitted from sources such as radio stations, TV sta- tions, amateur radio (HAM) transmitters, two way radios, and cellu- lar phones.

4.EMI can also be produced by conducted sources or electro-static discharge (ESD).

The sources of EMI fall into three broad types:

1. Hand-Held Transceivers:

The antenna is usually mounted directly on the unit. These include:

•Citizens band (CB) radios

•“Walkie-talkies”

•Security, fire and police radios

•Cellular phones

•Lap-top computers with phone or fax

•Other personal communication devices

NOTE– These devices can transmit signals while they are on, even if not in use.

2. Medium-Range Mobile Transceivers:

These include two-way radios used in police cars, fire trucks, ambulances and taxi cabs. The antenna is usually mounted on the outside of the vehicle.

3. Long-Range Transceivers:

These include commercial radio and TV broadcast antenna towers and amateur (HAM) radios. Note: The following are not likely to cause EMI problems: Lap-top computers (without phone or fax), Cordless phones, TV sets or AM/FM radios, CD or tape players.
