NOTE 1 At 80MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the Patient Monitor is used exceeds the applicable RF compliance level above, the Patient Monitor should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the Patient Monitor.
b Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 1V/m(80-800MHz)
&3V/m(800-2500MHz).

Portable and mobile RF communications
equipment should be used no closer to
any part of the CMS8000 Patient Monitor,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency

according to the transmitter
manufacturer and d is the recommended
separation distance in meters (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic
site survey, should be less than the
a
compliance level in each frequency range.
