Note1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note2: These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects, and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/
cordless) telephones and land mobile 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 OMRON BPM is used exceeds the applicable
RF compliance level above, the OMRON BPM should be observed to
verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the OMRON
BPM.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than
3
V/m.
where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter
manufacturer and
d
is the
recommended separation distance in
meters (m).
Field strengths from fixed RF
transmitters as determined by an
electromagnetic site survey,
a
should be less than the compliance
level in each frequency range.
b
Interference may occur in the vicinity
of equipment marked with the
