8.4 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:
•
T
ur
n
equipment
in the vicinity
off and on to isolate the offending
equipmen
t.
•
Reor

or relocate the other receiving
