INSTRUCTION MANUAL
Conducted 3Vrms
RF IEC 150kHz 3V
61000-4-6 to 80MHz
Radiated 3V/m
RF IEC 80MHz 3V/m
61000-4-3 to 2.5GHz
NOTE1 At 80MHz and 800MHz, the higher frequency range applies.
NOTE2 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 situation 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 model MD300M
Pulse Oximeter is used exceeds the applicable RF compliance level above, the Pulse
Oximeter should be observed to verify normal operation. If abnormal performance is
observed, the additional measures may be necessary, such as reorienting or relocating the
model MD300M Pulse Oximeter.
b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
MD300M
Portable and mobile RF
communications equipment should be
used no closer to any part of the model
MD300M Pulse Oximeter, including
cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended separation distance
80MHz to 800MHz
800MHz to 2.5GHz
Where P is the maximum output
power rating of the transmitter
in Watts (W) according to the
transmitter manufacture and d is the
recommended separation distance in
meters (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,a should
be less than the compliance level in
each frequency range.b
