V. EMI (ELECTROMAGNETIC INTERFERENCE)

Heed all warnings to reduce the risk of unintended brake release or scooter move- ment:

1.Beware of the danger from hand-held transceivers. Never turn on or use a hand-held transceiver while power to your scooter is on. Use extra care if you believe that such a device may be in use near your scooter.

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

3.If unintended movement occurs, turn your scooter 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. (A “transceiver” is a device that both sends and receives radio wave signals).

2.There are a number of sources of intense EMI in your daily environment.

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

3.Powered scooters 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.

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 scooter, 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 scooter. This could create a safety haz- ard, 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.
