Electromagnetic Interference

1.2.7

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:
Large equipment using a switching relay for its power on/off may affect monitoring system operation.
Do not operate the monitoring system in such environments.

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:
This 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 pulse oximetry cables away from the susceptible device.

Caution:
Be aware of possible interference from sources of electromagnetic interference, such as cellular phones,
radio transmitters, motors, telephones, lamps, electrosurgical units, defibrillators, and other medical
devices. If pulse oximetry readings are not as expected for the patient's condition, remove the sources
of possible interference.

Connections with Other Equipment

1.2.8

Caution:
Accessory equipment connected to the monitoring system's data interface must be certified according
to IEC 60950-1 for data-processing equipment. All combinations of equipment must be in compliance
with IEC 60601-1 Requirements for Medical Electrical Systems. Anyone who connects additional
equipment to the signal input or signal output port configures a medical system and is therefore
responsible for ensuring the system complies with the requirements of IEC 60601-1, IEC
60601-1-2:2007, and IEC 60601-1-2:2014.
