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 select option 3, or your local
Nellcor representative.
