 Attention Other types of hand-held devices, such as cordless phones, laptop computers,

AM/FM radios, TV sets, CD players, cassette and small appliances such as

electric shavers and hair dryers are not , likely to cause EMI problems to your

powered power wheelchair .

■ POWERED POWER WHEELCHAIR ELECTROMAGNETIC INTERFERENCE (EMI)

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 closer to the powered s control

system of power wheelchair while using these devices. This can affect powered power wheelchair

movement and braking. Therefore, the warnings listed below are recommended to prevent possible

interference with the control system of the powered power 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 power wheelchair and

motorized power wheelchair. Following the warnings listed below should reduce the chance of

unintended brake release or powered power wheelchair movement which could result in serious

injury.

1. Do not operate hand-held transceivers-receivers, such as citizens band (CB) radios, or turn ON

personal communication devices such as cellular phones, while the powered power 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 power wheelchair OFF as

soon as it is safe;

4. Be aware that adding accessories or components, or modifying the powered power 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 power wheelchair).

5. Report all incidents of unintended movement or brake release to the powered power wheelchair

manufacturer, and note whether there is a source of EMI nearby.

■ IMPORTANT INFORMATION

1. 20 Volts per meter (V/m) is a generally achievable and useful immunity level against EMI

(the higher the level, the greater the protection);

2. This product has an immunity level of 20 V/m without any accessories and connected to it.
