ELECTROMAGNETIC INTERFERENCE AND WARNINGS

CAUTION: It is very important that you read this information regarding the possible

effects of Electromagnetic Interference on your motorized scooter.

Powered wheelchairs and motorized scooters may be susceptible to electromagnetic

interference (EMI), which is interfering electromagnetic energy (EM) emitted from sources

such a radio stations, TV stations, amateur radio (HAM) transmitters, two-way radios, and

cellular phones. The interference (from radio wave sources) can cause the motorized

scooter to release its brakes, move by itself, or move in unintended directions. It can also

permanently damage the motorized scooter control system. The intensity of the interfering

EM energy can be measured in volts per meter (V/m). Each motorized scooter 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. The immunity level of this motorized scooter model is not known.

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.on the transmitting unit. Examples include: citizens band (CB) radios, "walkie talkie,"

security, fire, and police transceivers, cellular telephones, and other personal communication

devices;

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.

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, so far as

we know, are not likely to cause EMI problems to your motorized scooter.

Motorized Scooter Electromagnetic Interference：

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 motorized scooter control system while using these devices. This can affect motorized

scooter movement and braking. Therefore, the warnings listed below are recommended

to prevent possible interference with the control system of the motorized scooter.

Warnings：

Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur

radio (HAM) transmitters, two-way radios, and cellular phones can affect motorized scooters.

Following the warnings listed below should reduce the chance of unintended brake release

or motorized scooter 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 motorized scooter is turned ON;
