3.3 Effects of electromagnetic interference on the product and on the user
CAUTION
Use of mobile devices with electromagnetic emissions (e.g., mobile phones)
Falling, collision with persons or objects due to interference with the control signals
► Turn all mobile devices off while driving, since the driving characteristics of the product are affected by elec­
tromagnetic fields.
►
Turn the control unit off when it is not required, since the product may generate electromagnetic fields that
can cause interference with other devices. The product has been tested according to EMC regulations.
► Notwithstanding compliance with all applicable EMC directives and standards, the product can be affected by
interference from other electric devices (e.g., department store EAS systems) or cause interference with such
devices. If this occurs, move your product outside the interference range.
• Powered wheelchairs may be susceptible to electromagnetic interference (EMI), which is interfering electro­
magnetic energy (EM) emitted from sources such as radio stations, TV stations, amateur radio (HAM) transmit­
ters, two-way radios, and cellular phones.
• The interference (from radio wave sources) can cause the powered wheelchair to release its brakes, move by
itself, or move in unintended directions.
• It can also permanently damage the powered wheelchairs control system.
• Because EM energy rapidly becomes more intense as one move closer to the transmitting antenna (source),
the EM fields from hand-held radio wave sources (transceivers) are of special concern. It is possible to uninten­
tionally bring high levels of EM energy very close to the powered wheelchair's control system while using these
devices. This can affect powered wheelchair movement and braking.
• 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 powered wheelchair.
