IV. NOTICE– READ BEFORE USE
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.
C. REVIEW THIS MANUAL OFTEN
Before using this chair you, and each person who may assist you, should
read this entire Manual and make sure to follow all instructions. Review the
warnings often, until they are second nature to you.
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.
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).

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
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.
