Electromagnetic propagation is affected by absorption and reflection

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 site
survey should be considered. If the measured field strength in the
location in which The Pulse Oximeter is used exceeds the applicable RF
compliance level above, the Pulse Oximeter should be observed to
