NotE: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.

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 and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic sire survey should be considered. If the measured field strength in the location in which the InSpectra StO
Oxygenation Monitor is used exeeds the applicable RF compliance level above, the InSpectra StO
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the InSpectra
StO Tissue Oxygenation Monitor.
