Portable and mobile RF communica-

closer to any part of the LD-207U
Mesh Nebulizer Equipment, including
cables, than the recommended sepa-
ration distance calculated from the
equation applicable to the frequency of
the transmitter.

Field strengths from

xed RF trans-
mitters, as determined by an electro-
magnetic site survey,

should be less
than the compliance level in each
frequency range.
d
Interference may occur in the vicinity
of equipment marked with the
following symbol:
Note 1 At 80MHz and 800MHz, the higher frequency range applies.
Note 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and re
fl
ection from structures, objects and people.
ª Field strength from
fi
xed transmitters, such as base stations for radio 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 transmit-
ters, an electromagnetic site survey should be considered. If the measured
fi
eld strength in the
location in which the Model LD-207U Mesh Nebulizer is used exceeds the applicable RF compli-
ance level above, the Model LD-207U Digital Blood Pressure Monitor should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the Model LD-207U Mesh Nebulizer.
b
Over the frequency range 150KHz to 80MHz,
fi
eld strength should be less than 3 V/m.
