AlarmView™ System User’s Guide
Electromagnetic Interference (EMI)
The AlarmView transmitter has been tested and found to comply with the
limits for medical devices to the FDA guidance for electromagnetic
compatibility (EMC). These limits are designed to provide reasonable
protection against harmful interference in a typical medical installation.
u It is possible that high levels of radio frequency or conducted
frequency electromagnetic interference due to close proximity or
strength of source may result in performance disruption of
transmitter.
The transmitter is designed for use as a mobile device as
defined by the Federal Communications Commission (FCC). Do
not place the transmitter on a patient’s or user’s body. Ensure
that the transmitter is located at least 20 cm (8 inches) from a
patient or user’s body. Location of the transmitter closer than 20
cm (8 inches) to a person’s body will void the user’s FCC
authority to operate the equipment.
The Nellcor NPB-290, NPB-295, N-395, and N-3000 pulse oximetry
monitors are not designed for use in environments in which the pulse
can be obscured by EMI. Interference may cause measurements that
seem inappropriate or monitor may not seem to operate correctly. The
AlarmView System may generate alarms or error messages during these
conditions.
The AlarmView System generates, uses, and can radiate radio-fre-
quency energy and – if not installed and operated according to these
instructions – may cause interference with other devices in vicinity.
Evidence of disruption may include erratic readings, amber Tx LED,
equipment ceasing to operate, or other incorrect functioning. If this
occurs, survey the site to determine the source of disruption, and take
the following actions to eliminate the source(s):
