av. When traveling with a wheelchair, you may need to use a lift/elevator to assist in
transportation. It is recommended that you carefully read the instructions, speci-
fications and safety information set forth by the elevator/lift manufacturer before
using the product.
aw. Do not modify the drive in any way. This will lead to loss of warranty.
Information on electromagnetic interference - EMI
Studies of electromagnetic interference (EMI) have shown that it adversely affects the
operation and control of electrically powered mobile devices.
EMI can come from a variety of sources, such as cell phones, two-way radios, radio
stations, TV stations, amateur radio (HAM) transmitters, wireless computer links, micro-
wave signals, paging transmitters and transmitters used by emergency vehicles. EMI
waves can cause unintended movement of the wheelchair or damage to the controller.
Every electrically powered mobile device has a certain immunity to electromagnetic
interference. The higher the immunity level, the greater the protection. The intensity of
interference can be measured in volts per meter (V/m). Current technology allows for an
immunity level of 20 V/m, which provides protection against the most common sources
of electromagnetic interference. As you get closer to the source, electromagnetic inter-
ference becomes more intense. Special attention should be paid to electromagnetic
interference from hand-held radio devices. It is possible to unintentionally bring high
levels of EMI close to the front drive control system, which can affect movement and
braking. To prevent possible interference with the front drive control system, follow
the warnings below:
WARNING!
Do not use hand-held radio transmitters such a CB-radio or cell phone near
a front drive control system.
WARNING!
Pay attention and stay away from nearby transmitters, such as radio or TV
stations.
WARNING!
Any “serious incident” related to the device must be reported to the man-
ufacturer and to the competent authority of the Member State in which
the user or patient resides.
