Putting on the chest strap 
„ 
Tighten the chest strap with the elastic tension 
belt. Adjust the length of the belt such that the 
belt is snug, but neither too loose nor too tight. 
Position the belt around the chest such that the 
logo is facing outwards and in the correct posi-
tion directly over the breast bone. For men, the 
chest belt should be located directly below the 
pectoral muscles, for women, directly below the 
breast.  
 
„ 
Since optimal contact between the skin and the heart rate sensors 
can not be created immediately, it may take some time until the 
heart rate is measured and displayed. If necessary, alter the 
position of the transmitter in order to achieve optimal contact. 
Most of the time, sufficient contact is achieved through the 
accumulation of sweat beneath the chest strap. You can, 
however, also wet the contact points on the inside of the chest 
strap. For this, lift the chest strap up from the skin slightly and wet 
the two sensors with saliva, water or ECG gel (available at the 
chemistry). The contact between the skin and chest strap may not 
be interrupted also with greater movements of the thorax such as 
during deep breathing. Significant chest chair can interfere with 
and even prevent contact.  
„ 
Put on the chest strap a few minutes before starting in order to 
warm it up to body temperature and establish optimal contact.
