If the user of the
model MD300I Pulse
Oximeter requires
continued operation
during power main
interruptions, it is
recommended that the
model MD300I Pulse
Oximeter be powered
from an uninterruptible
power supply or a
battery.

For EQUIPMENT and SYSTEM that are not LIFE-SUPPORTING
Guidance and manufacturer’s declaration – electromagnetic immunity
The model MD300I Pulse Oximeter is intended for use in the electromagnetic specified
below. The customer of the user of the MD300I Pulse Oximeter should assure that it is
used in such an environment.

Portable and mobile RF
communications equipment should be
used no closer to any part of the model
MD300I 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
Interference may occur in the vicinity of
equipment marked with the following
symbol:
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
MD300I 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 MD300I Pulse Oximeter.
b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
