Guidance and manufacturer's declaration - electromagnetic immunity
OMRON BPM including AC-adapter is intended for use in the electromagnetic environment specified
below. The customer or the user of this OMRON BPM including AC-adapter should assure that it is
used in such environment.
IEC 60601
Immunity test
test level
Conducted RF 3 V rms
IEC 61000-4-6 150 kHz to
80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to
2.5 GHz
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 including AC-adapter is used exceeds the applicable RF compliance level
above, the OMRON BPM including AC-adapter 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 including AC-adapter.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Compliance
level
Portable and mobile RF communications equipment
should be used no closer to any part of the OMRON
BPM including AC-adapter and cables, than the
recommended separation distance calculated from the
equation appropriate to the frequency of the transmitter.

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).
