EM1 (ELECTROMAGNETIC INTERFERENCE)
Caution: This device has been tested and found to comply
with the limits for medical devices to the IEC 601-1-2:1993,
EN 60601-1-21994, Medical Device Directive 93142lEEC.
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 healthcare 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-395 is not 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 seein to operate correctly.
Erratic readings, cessation of operation, or other incorrect
functioning inay evidence disruption. 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
011
to isolate the
offending equipment.
Reorient or relocate the interfering equipment.
Increase the separation between the interfering equipment
and this equipment.
The N-395 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 Mallinckrodt Technical Services
Department or your local Malli~lckrodt representative.
