NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations, Electromagnetic propagation is affected by
absorption and refl ection structures, objects and people.
a Field strengths from fi xed 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
theoretically with accuracy. To assess the electromagnetic environment due to fi xed RF transmitters, an
electromagnetic site survey should be considered. If the measured fi eld 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, fi elds strengths should be less than 3 V/m
Recommended separation distances between portable and mobile RF communications equipment
and the EQUIPMENT or SYSTEMS -For all EQUIPMENT and SYSTEMS that are not LIFE-SUPPORTING
Recommended separation distances between 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.
