a Field strengths from fixed transmitters, such as base station for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted t
heoretically 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 (18710) should be observed to verify normal operation. If abnormal performance is
observed, additional measurements may be necessary, such as reorienting of the relocating the Pulse
Oximeter (18710).
b Over the frequency range 150 kHz to 80 MHz, fields strengths should be less than 3 V/m

portable and mobile RF communications equipment and Pulse Oximeter (18710)
The Pulse Oximeter (18710) is intended for use in electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Pulse Oximeter (18710) can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Pulse Oximeter (18710) as recommended below,
according to the maximum output power of the communications equipment.
