Reducing Electromagnetic Interference

The MX40 and associated accessories can be susceptible to interference
from other RF energy sources and continuous, repetitive, power line bursts.
Examples of other sources of RF interference are other medical electrical
devices, cellular products, information technology equipment, and
radio/television transmission. If interference is encountered, as
demonstrated by artifact on the ECG or dramatic variations in physiological
parameter measurement values, attempt to locate the source. Assess the
following:
Is the interference due to misplaced or poorly applied electrodes or
sensors? If so, re-apply electrodes and sensors correctly according to
directions in Chapter 6.
Is the interference intermittent or constant?
Does the interference occur only in certain locations?
Does the interference occur only when in close proximity to certain
medical electrical equipment?
Once the source is located, attempt to attenuate the interference by
distancing the MX40 from the source as much as possible. If assistance is
needed, contact your local service representative.

Restrictions for Use

Artifact on ECG and other physiological waveforms caused by
electromagnetic interference should be evaluated by a physician or
physician authorized personnel to determine if it will negatively impact
patient diagnosis or treatment.

Electromagnetic Compatibility (EMC) Specifications

Take special precautions regarding electromagnetic compatibility (EMC)
when using medical electrical equipment. You must operate your
monitoring equipment according to the EMC information provided in this
book. Portable and mobile radiofrequency (RF) communications equipment
can affect medical electrical equipment.
Accessories Compliant with EMC Standards
All accessories listed in the accessories section comply, in combination with
the MX40, with the requirements of IEC 60601-1-2:2001 + A1:2004.
