Guidance and manufactures declaration - electromagnetic immunity
The Oxygen Saturation Monitor Model PULSOX-300 is intended for use in the electromagnetic
environment specified below. The customer or the user of the Model PULSOX-300 should assure
that it is used in such anenvironment.

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) telephone 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 PULSOX-300 is used exceeds
the applicable RF compliance level above, the PULSOX-300 should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
PULSOX-300.
b
Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
Portable and mobile RF communications
equipment should be used no closer to
any part of the PULSOX-300, than the
recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
