Electromagnetic Interference (Emi) - Quickie Q50 R Carbon Directions For Use Manual

2.5 Electromagnetic interference (EMI)

DANGER!
Electromagnetic interference is from external electromagnetic wave energy (like radios, TV transmission stations, CB radio waves,
garage door starters, radio phones,etc. ). Electromagnetic interference may affect the control system of the power wheelchair. Some
interference may lead to the brake failure, power on automatically, or steering failure, also may lead to the permanent damages to
the control systems. Below cables information are provided for EMC reference.

• Important information regarding Electro Magnetic Compatibility (EMC)
• This electrical medical equipment needs special precautions regarding EMC and needs to be put into service according to the EMC
information provided in the user manual; The equipment conforms to this IEC 60601-1-2:2014 standard for both immunity and
emissions. Nevertheless, special precautions need to be observed:
• The equipment with ESSENTIAL PERFORMANCE, has been designed to be used to be in an indoors environment.
ESSENTIAL PERFORMANCE:
• WARNING: Use of this equipment adjacent with other equipment should be avoided because it could result in improper operation.
If such use is necessary, this equipment and the other equipment should be observed to verify that they are operating normally.
• The use of accessories, transducers and cables other than those specified or provided by the manufacturer of this equipment
could result in increased electromagnetic emissions or decreased electromagnetic immunity of this equipment and result in
improper operation.
• WARNING: Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should
be used no closer than 30 cm (12 inches) to any part of the Q50 R Carbon, including cables specified by the manufacturer.
Otherwise, degradation of the performance of this equipment could result.
• WARNING: If the wheelchair is being used near (e.g. less than 1.5 km from) AM, FM or TV broadcast antennas, before using this
equipment, it should be observed to verify that it is operating normally to assure that the equipment remains safe with regard to
electromagnetic disturbances throughout the expected service life.
• When the AC input voltage is interrupted, the equipment will stop battery charging and if the power supply restored, it could be
recovered automatically.
