User's Manual

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic 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 SF-371 body fat scale is used exceeds the applicable RF compliance level above, the
SF-371 body fat scale should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as reorienting or relocating the SF-371 body fat scale .
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.

Recommended separation distances between
portable and mobile RF communications equipment and the SF-371 body fat scale
The SF-371 body fat scale is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the SF-371 body fat scale can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the SF-371 body
fat scale as recommended below, according to the maximum output power of the communications equipment
