Troubleshooting
EMI (Electromagnetic Interference)

Caution: This device has been tested and found to comply with
the limits for medical devices to the IEC 60601-1-1-2 (second
edition), EN60601-1-2, and the Medical Device Directive 93/42/
EEC. These limits are designed to provide reasonable protection
against harmful interference in a typical medical installation.
However, 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
performance of this device.
The N-600x is designed for use in environments in which the pulse
can be obscured by electromagnetic interference. During such
interference, measurements may seem inappropriate or the monitor
may not seem to operate correctly.
Disruption may be evidenced by erratic readings, cessation of
operation, or other incorrect functioning. If this occurs, the site of use
should be surveyed to determine the source of this disruption, and the
following actions taken to eliminate the source:
•
Turn equipment in the vicinity off and on to isolate the
offending equipment.
•
Reorient or relocate the interfering equipment.
•
Increase the separation between the interfering
equipment and this equipment.
The N-600x generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with these instructions,
may cause harmful interference with other devices in the vicinity.
If assistance is required, contact Nellcor's Technical Services
Department, 1.800.635.5267, or your local Nellcor representative.
