The battery used in the watch is a CR 2032.
Watch :
We recommend that you not change the watch batteries yourself,
but rather have the job done by a specialized DECATHLON repair shop. If you change
the battery yourself, you may damage the seal and lose both the water tightness
and guarantee on the product.
Please check the availability of the battery with your dealer before replacing it.
Pectoral belt :
If the heart rate indications become inconsistent, or if the
heart monitor light on the watch does not flash when it is close to the belt, it may
be necessary to change the battery in the chest belt.
You can easily change the belt battery yourself, without the aid of any particular tool.
Changing procedure :
1
unscrew with the aid of a coin, then remove the cover of the battery compartment.
2
remove the old battery by tapping on the opposite side of the belt.
3
replace the used battery with a lithium 3V type CR2032 battery without touching
it on its 2 terminals (it may discharge), with the +terminal (printed surface) up.
4
carefully replace the cover, then screw it down again by a quarter turn to the
"CLOSED" position
If there is a problem, contact your retailer.
