Precautions for use

EN
Always weigh yourself
on a hard, flat floor.
Do not weigh yourself
on a carpet or rug.
Warning: the use of
this appliance is
forbidden for wearers
of pacemakers or other
electronic medical
equipment because of
the risk of disruption
due to the electric
current.

Using for the first time

Important: when recording your personal data:
– Bodysignal must remain set on the floor,
– use just one finger to press the buttons,
– the scales must not be pressed in any other way than by the fingers on the
keys and must not be held.

To be fully satisfied with this appliance, measuring and
weighing must always be conducted under the same
conditions:
– Always weigh yourself in bare feet (direct contact
with the skin). Your feet must be dry and properly
positioned on the electrodes (see page 2). Beware
that if your feet have too much hard skin the
measurement may be affected.
– preferably once a week first thing in the morning
(so as not to be affected by the weight fluctuations
during the day related to the meals, digestion and
physical activity of the individual)
– 1/4 of an hour after waking up, so that the water
in your body is distributed in the lower limbs.
It is also important to ensure that there is no contact
between the legs (thighs, knees, calves) or between the
feet. If necessary, slip a sheet of paper between your
legs.

Measuring principle

When you step on the scales, barefoot, an electric current
of very low intensity is transmitted through the body via
the electrodes.
This current, which travels from one foot to the other,
encounter difficulties when it has to pass through fat.
This resistance of the body, called bioelectrical
impedance, varies according to gender, age and height
of the user, and makes it possible to determine body fat
and its limits.
This device is perfectly safe because it operates with a
very low current (4 X 1.5 V batteries).
However, there are risks of distorted measurements in
the following cases:
– users with fever
– children under 6 years (the appliance is uncalibrated
below this age)
– pregnant women (but perfectly safe)
– people on dialysis, those with oedema in the legs,
people with dysmorphism
