Guidance and manufacture's declaration – electromagnetic
immunity
NOTE 1 At 80MHz and 800MHz, 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/cord-
less) telephones and land mobile radios, amateur radio, AM and FM radio broad-
cast 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 SPO 55 Pulse Oximeter is used exceeds the applicable RF compliance level
above, the SPO 55 Pulse Oximeter should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the SPO 55 Pulse Oximeter.
b Over the frequency range 150 KHz to 80 MHz, field strengths should be less than
3 V / m.
