Battery
Battery replacement will be required from time to time, and should
occur when:
• The display fades in part or completely
• The Heart Rate function will not activate
To replace the battery of your Sportline Solo 910 Heart Rate Watch, we
recommend that this be done by a watch repair service center. This
will ensure that the water resistance will be retained after battery
replacement.
