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 reflection from structures, objects and people.
A fixed transmitter, such as the base station of wireless (cellular / cordless) telephone and ground
mobile radio, amateur radio, am and FM radio broadcast and television broadcast, its field strength
cannot be predicted accurately in theory. In order to evaluate the electromagnetic environment of
fixed RF transmitter, the survey of electromagnetic field should be considered. If the measured field
strength of the air smart pulmonary function tester is higher than the above applicable RF
compliance level, observe the air smart pulmonary function tester to verify its normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or
positioning the air smart lung function tester.
B in the whole frequency range of 150khz-80mhz, the field strength shall be lower than 3V / m.
Recommended separation distances between portable and mobile RF communications
equipment and the device – for device that is not LIFE-SUPPORTING
Recommended separation distances between portable and mobile RF communications
equipment and the device
transmitter manufacturer and d is
the recommended separation
distance in meters (m).
Field strengths from fixed RF
transmitters, as by an electromag-
netic site survey,*2) should be less
the compliance level in each
frequency range.*3) Interference
may occur in the vicinity of
equipment marked with the
