Portable and mobile RF communications
equipment should be used no closer to any part
of the InBody S10, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
Recommended separation distance
d=1.2√P
d=1.2√P 80 MHz to 800 MHz
d=2.3√P 800 MHz to 2.5 GHz
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 metres (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.

Interference may occur in the vicinity of
equipment
marked with the following symbol:
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 radios, amateur 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 InBody S10 is used exceeds the
applicable RF compliance level above, the InBody S10 should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the InBody S10.
ᵇ Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
