How do I replace my watch battery (on all items except for heart rate monitor chest straps)?
Battery replacement will be required from time to time, and should occur when: • The display fades in part or completely • The functions not activate • Backlight System does not operate To replace the battery of your Sportline heart rate monitor product, we recommend 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. For stopwatches and pedometers you can replace on your own by removing the battery cover with a screwdriver, properly discarding the old battery, inserting a new battery, and securely fastening the cover back on.
