I. SAFETY NOTES
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 consid-
ered. If the measured field strength in the location in which the Body Composition Analyzer
MA801 is used exceeds the applicable RF compliance level above, the Body Composition
Analyzer MA801 should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the
Body Composition Analyzer MA801
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
The Body Composition Analyzer MA801 is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The customer or the user of the Body Compo-
sition Analyzer MA801 can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the
Body Composition Analyzer MA801 as recommended below, according to the maximum output
power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in metres (m) can be estimated using the equation applicable 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.
NOTE1
At 80 MHz and 800 MHz, the separation distance for 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.
