WARNING: When you are inside the function «personal 
data input» the scale will turn off automatically if no button 
is pressed within 10 seconds.

2.

2. Wait a few seconds and when «0.0» 

8 appears on the display, 

press the USER button 

2. Press the USER button 2 again 

until the memory location required appears. The data inserted 
will be viewed on the display screen and then «0.0kg»

appear.

3. Step on the scale making sure you place your bare feet over the 

two electrodes. The display will show the following data in 
sequence:

− weight 9

− the «bF %» (bodyfat) sign AO

− the percentage of fat in your body AP

− the «H20 %» (water) sign AQ

− the percentage of water in your body AR
Compare the percentage of bodyfat (bF) obtained with the 
parameters listed in the «Body fat mass percentage» table: if it 
falls outside the normal values, we suggest you consult your 
physician. Estimate the percentage of water (H

O) as displayed 

in the paragraph «Water percentage».

4. The scale will turn off automatically after approx. 5 seconds.

WARNING: If the display is not on «0.0» 

8, it will not be 

possible to figure out your weight and calculate the fat and 
water percentage. If the «ERR» 

AS sign turns on, it means 

that an error has taken place during the measurement. 
Start the entire procedure again from the very beginning.
