REPLACING THE WATCH BATTERY
The Sportline Cardio 630 watch uses a single CR2032 3v lithium battery.
Battery replacement will be required from time to time, and 
should occur when:

3.Backlight System does not operate
To replace the battery of your Sportline Cardio 630, we recom- mend you take it to a watch repair service center or certified jeweler. This will ensure that the water resistance will be retained after battery replacement.
