Reducing EMI (Electromagnetic Interference)

WARNING:
EMI disruption can cause erratic readings, cessation of operation, or other
incorrect functioning.

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.

Caution:
This device has been tested and found to comply with the limits for medical
devices related to IEC 60601-1-2: 2007. These limits are designed to provide
reasonable protection against harmful interference in a typical medical
installation.
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-defi-
nition television), it is possible that high levels of such interference due to close
proximity or strength of a source might result in disruption of monitoring system
performance. Reference
Electromagnetic Emissions , p. 2-7.
The monitoring system is designed for use in environments in which electro-
magnetic interference might obscure the client’s pulse. During such interfer-
ence, measurements may seem inappropriate or the monitoring system may
not seem to operate correctly. EMI disruption can cause erratic readings, ces-
sation of operation, or other incorrect functioning. If this occurs, survey the site
