General information
The measured values serve only as indica­
tors to observe long­term changes. They
do not substitute medical supervision or a
doctor's consultation. For more information
about your body fat, body water, bone mass
and muscle mass percentages and their
ideal values, please consult your physician.
Tip: To collect comparable values it is
recommended to weigh yourself each day
at the same time and under the same con­
ditions (preferably three hours after meals
or exercise).
Note: The measurement results are not
meaningful for children under 10 years
of age.
The individual measurement values can
not be realistically added because muscles
contain water, for example.
L
Activity mode
Scientific studies have shown that the body
composition of competitive athletes varies
significantly from recreational athletes and
people who don't exercise. The scale thus
allows you to specify your own personal
fitness on five different levels.
Activity levels
no sporting activity
1
light, sporadic sporting activity
2
3 light but regular sporting activity
regular sporting activity
4
5 endurance / performance sport

How do the scales measure body fat?
The scales measure the body fat percentage
using the Bioelectrical Impedance Analysis
(BIA) method. To take this measurement,
the appliance sends an extremely weak
electrical signal through your body
and measures your body's resistance
(impedance) to this signal. The impedance
is affected by your body's composition.
Since they contain water, your muscles and
organs are good conductors. Fat, on the
other hand, is a bad conductor.
The scales compute the body fat percent­
age from the measured resistance and the
values stored in the User Profile (height,
age, gender).
Since people's body fat percentage is highly
individual, the values shown in Table F on
the fold­out page are only guidelines.
M
Body water values
The body fat and body water measurements
are influenced by the amount of water in
your body. The water volume is affected by
the time of day, physical exertion, bathing
or showering, menstruation, eating, drinking
and other factors. Illnesses or medications
can also affect the measurement.
Please also refer to Table E on the
fold­out page.
N
What is muscle mass?
This function displays the computed skel­
etal muscle mass (guideline value) in your
body. Human beings have more than 600
muscles. They play an important role
(motion, posture, etc.) and consume energy.
As muscle mass increases (more activity
and exercise), the consumption of energy
(calories) rises and the body fat percentage
decreases.
Please also refer to Table G on the
fold­out page.
