OVERLOAD INDICATOR
When the scale is overloaded (over 5000g), “oL” will display on the LCD. Please remove
the weight immediately to avoid the damage of the scale.
ATTENTION
1， Place the scale on a hard and flat surface to ensure the greatest accuracy and
reliability.
2， Do not use any chemical cleanser to clean the scale. Clean your scale with a damp
cloth, but do not immerge your scale into any liquid, as this can damage the inner
parts.
3， To ensure that the scales of life, please do not over-heat scale placed in the
environment.
4， Remove the batteries if the scale is not being used for a long time.

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.

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.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.
