Pulse Oximeter for Sleep Screening Operation Manual
EMI Interference
CAUTION! This device has been tested and found to comply within the limits for medical
devices to IEC 601-1-2:1993, EN 60601-1-2:1994, 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 the heath-care and home environments (for
example, cellular phone, mobile two-way radios, electrical appliances), 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 monitor 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 monitor may not operate correctly.
The monitor 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. Disruption may be evidenced by erratic readings, cessation of operation, or other
incorrect function. If this occurs, the site of use should be surveyed to determine the source of this
disruption, and actions taken to eliminate the source:
Turn equipment in the vicinity off and on to isolate the offending equipment.
Reorient or relocate the other receiving device.
Increase the separation between the interfering equipment and this equipment.
If assistance is required, contact the Smiths Medical PM, Inc. Service Department or your local
representative.
