GUIDANCE AND MANUFACTURER’S DECLARATION – ELECTROMAGNETIC IMMUNITY
The Balance Living
TM
Precision LIFE TRACK body analysis scale is intended for use in the electromagnetic environment specified
below. The user of the Balance Living
TM
Precision LIFE TRACK body analysis scale
should assure that it is used in such an environment.

Portable and mobile RF communications equipment should be used no
closer to any part of the Balance LivingTM Precision LIFE TRACK body
analysis scale, including cables, than the recommended separation
distance calculated from the equation applicable to the frequency of the
transmitter.
Recommended separation distance
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).
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:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 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 Balance Living
TM
Precision LIFE TRACK body analysis scale is used exceeds the applicable RF
compliance level above, the Balance Living
TM
Precision LIFE TRACK body analysis scale should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the Balance Living
TM
Precision LIFE TRACK body analysis scale.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
