•For the SC-240MA; Ensure you use the original AC adapter. Using an AC adapter (model A30930G)
other than the original one may cause malfunction.
Do not insert or remove the plug by the cable.
•Do not take measurements while using transmitters, such as mobile phones, which may
affect readings.

This equipment sends out a very weak electric current to measure impedance (electrical
resistance) of the body. Therefore, in principle, users need to use this equipment with bare feet.
Moreover, since impedance fluctuates in accordance with the distribution of body fluid, please
observe the following instructions for accurate measurement.
•To prevent a possible discrepancy in measured values, avoid taking measurements after vigorous
exercise until sufficiently rested.
•To prevent inaccurately low body fat percentage measurements and other measurement errors,
always hold both arms straight down when taking measurements.
•As changes in body water and body temperature can have a major impact on measurements,
measurements should be made every day at the same time under similar conditions (always
urinating before taking measurements, etc.) to get a more accurate picture of the measurements
over time.
•Also, make sure the soles of feet are free of excess dirt, as this may also act as a barrier to the mild
current.
•False results may be reported after excessive food / fluid intake, or after periods of intense exercise.
•This equipment is designed for the majority of the population leading healthy lives with a regular
lifestyle. For people suffering from sickness, or whose lifestyle is very different from the norm, it is
recommended that the data from this product should not be used as an absolute value, but rather
as a reference to observe the rate change.
•If there are calluses on the soles of the feet, or an individual is wearing thin nylons, accurate
measurement may still be possible. Place 0.5ml of water in the centre of each electrode. This will act
as a conductant, and may allow the current to pass freely through a thin barrier.
•Measurement is sometimes impossible on a surface that is strongly vibrating. In this case, please
move the equipment onto a surface with little vibration.
Since this equipment is accurately manufactured and adjusted, please observe the following
instructions.
•Users must not disassemble or adjust this equipment. This should be done by trained maintenance
agents or certification offices designated under the NAWI directive.
•Never disassemble the equipment as this may cause malfunction. Users must not disassemble or
adjust this equipment. Please inspect the equipment in accordance with the regulations in your
country.
•Unplug the unit from the wall outlet when it will not be in use for long periods of time.
•Keep the electrodes clean by wiping them with disinfectant.
•Do not drop the unit, and avoid locations with constant vibration.
•Do not put this equipment in direct sunlight, close to heaters or near direct draughts from air
conditioners.
•When transferred to any location where there is a difference of more than 20˚C, wait 2 hours before
using.
•When disposing of this unit, please do so in accordance with the prevailing regulations in each
country.
