EMC Guidance
The ME EQUIPMENT or ME SYSTEM is suitable for home healthcare environments.
Warning: Don’t be near the active HF surgical equipment and the RF shielded room of an ME
system for magnetic resonance imaging, where the intensity of EM disturbances is high.
Warning: Use of this equipment adjacent to or stacked 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.
Warning: 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 equipment TMB-1491-BHJ including cables specified by the manufacturer. Otherwise,
degradation of the performance of this equipment could result.
