6.5. EMI (Electromagnetic Interference)
Warning: Electromagnetic emissions from the monitoring system may interfere with other
critical devices.
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 monitoring system, including cables. Otherwise, degradation of monitoring system
performance may result.
Warning: The use of accessories, sensors, and cables other than those specified may result
in poor performance of the monitoring system and increased electromagnetic emissions or
decreased electromagnetic immunity of the monitoring system.
Warning: The monitoring system is intended for use by healthcare professionals only. It
may cause radio interference or may disrupt the operation of nearby equipment. Mitigation
for such disruption may require re-orienting or relocating the monitoring system or
shielding the location.
Warning: Any radio frequency transmitting equipment or other nearby sources of electrical
noise may result in disruption of the monitoring system.
Warning: The monitoring system is designed for use in environments in which the signal
can be obscured by electromagnetic interference. During such interference, measurements
may seem inappropriate or the monitoring system may not seem to operate correctly.
Warning: EMI disruption can cause cessation of operation or other incorrect functioning.
Warning: The monitoring system should not be used adjacent to or stacked with other
equipment. If adjacent or stacked use is necessary, observe the monitoring system to verify
normal operation in the desired configuration. Technical alarms may indicate that the
configuration is not appropriate for the monitoring system.
Caution: This device has been tested and found to comply with the limits for medical
devices related to IEC 60601-1-2: 2007 and IEC 60601-1-2:2014. These limits are designed to
provide reasonable protection against harmful interference in a typical medical installation.
Caution: When operating medical electrical equipment, special precautions related to
electromagnetic compatibility (EMC) are required. Install the monitoring system according
to the EMC information included in this manual.
Caution: The monitoring system generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful
interference to other devices in the vicinity. If interference is suspected, move monitoring
system cables away from the susceptible device.
Caution: The use of an electrosurgical or electrocautery instrument in the vicinity of the
monitoring system may interfere with the signal and cause poor performance or no
readings at all.
Because of the proliferation of radio frequency transmitting equipment and other sources
of electrical noise in health care environments (for example, electrosurgical units, cellular
phones, mobile two-way radios, electrical appliances, and high-definition television), it is
possible that high levels of such interference due to close proximity or strength of a source
may result in disruption of monitoring system performance. See Manufacturer’s
Declaration, page 114.
