Owner´s Manual Permobil C500
NOTE! Other types of hand-held devices, such as cordless phones, laptop com-
puters, AM/FM radios, TV sets, CD players, and casette players, and small appli-
ances, such as electric shavers and hair dryers, so far we know, are not likely to
cause EMI problems to your powered wheelchair.
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 powered wheelchair's control system while
using these devices. This can affect powered wheelchair movement and brak-
ing. Therefore, the warnings listed below are recommended to prevent possible
interference with the control system of the powered 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 wheelchairs and motorized scooters. Following the warnings listed
below should reduced the chance of unintended wheel lock release or powered
wheelchair movement which could result in serious injury.
• Do not operate hand-held transceivers (transmitters/receivers), such as citi-
zens band (CB) radios, or turn ON personal communications devices, such
as cellular phones, while the powered wheelchair is turned ON.
• Be aware of nearby transmitters, such as radio or TV stations, and try to
avoid coming close to them.
• If unintended movement or wheel lock release occurs, turn the powered
wheelchair OFF as soon as it is safe.
• Be aware that adding accessories or components, or modifying the powered
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 wheelchair).
• Report all incidents of unintended movement or wheel lock release to the
powered wheelchair manufacturer, and note whether there is a radio wave source
near by.
