BMR (Basal Metabolic Rate / Energy expenditure)
The Basal Metabolic Rate (BMR) characterizes the energy
expenditure. The energy expenditure is used to describe the
amount of energy in in KCAL that the body requires per day
during complete rest, at an indifference temperature (28-
30 °C) and on an empty stomach for the maintenance of its
function (e.g. while sleeping).

BMI (Body Mass Index)
The Body Mass Index (BMI) refers the body weight to the
square of the body height.
BMI = Weight in kg: (body height in m x body height in m)
Example:
A woman weighs 55 kg and is 1.68 m tall. Her BMI is calcu-
lated as follows:
55 kg: (1.68 m x 1.68 m) ≈ 19.5 kg/m²
Normal weight
The value “square of the body height” is in no relation to the
body surface. The BMI is merely a rough reference value, as
it neither considers the build and gender, nor the individual
composition of the body mass from the fat and muscle tissue
of a human.
Reference values for the BMI

< 18.5 18.5 - 25 25 - 30 > 30
Please note that the interpretation of the BMI indicates
excess weight with very muscular bodies (bodybuilder). The
reason for this is that the far above-average muscle mass is
not considered in the BMI formula.
Display Error Messages
NOTE:
If an error message appears on the display, wait until the
device is turned off. Turn it on again to restart the opera-
tion. If the error display has not disappeared, take the
batteries out of the battery compartment for 10 seconds.
Display Indications Meaning
Self test (after inserting the batteries)
for perfect functioning of the display
Lo Battery is low
Err
The weight lies above the allowed
maximum weight.
Err2
The percentage of body fat content
lies above or below the limits of the
measuring scale.
Cleaning
CAUTION:
• Do not immerse the balance in water: the electronic
components can be damaged.
• Do not use a wire brush or any abrasive items.
• Do not use any acidic or abrasive detergents.
• Clean the device with a slightly moist cloth. Make sure
that no humidity or waters seeps into the device!
• Use a commercially sold detergent or soap for cleaning.
• Dry the device well after cleaning with a dry and soft
cloth.
Disposal

This symbol can be found on batteries/rechargeable batter-
ies which contain hazardous substances:
• Pb = contains lead
• Cd = contains cadmium
• Hg = contains mercury
• Li = contains lithium
