Replacing the batteries
You can change the batteries of the HR monitor and the chest strap
yourself. Please read how to change the battery in your HR monitor
in Chapter “Getting started”, Section “Insert battery/Change battery”.
The battery compartment of the chest strap is on the inside of the
chest strap. Use a coin to open the battery compartment. The posi-
tive pole (+) of the battery inserted must face upwards. Close the
battery compartment again carefully to guarantee impermeability.
Used batteries do not belong in the household gar-
bage. Dispose of these through your electronics
dealer or your local collecting point for recoverables.
You are legally required to do this. We will find this
symbol on batteries containing toxic chemicals:
Pb = battery contains lead
Cd = battery contains cadmium
Hg = battery contains mercury
