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 cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be
the measured field strength in the location in which The Pulse Oximeter(CMS60C) is used
considered. If
exceeds the applicable RF compliance level above, the Pulse Oximeter(CMS60C) should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the Pulse Oximeter (CMS60C) .
b
Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3V/m.
