F. WEARING MIO IN WATER & LOCKING
THE HEART RATE SENSOR
To prevent triggering the Smart Touch heart rate feature from accidental
readings due to contact with water or some clothing materials use the
heart rate Lock feature. Because water is a conductor, it will activate the HR
function. To protect the battery’s life while swimming or showering (although
wearing in the shower/bath/sauna is not recommended) always use MIO’s
heart rate Lock.
- To turn the HR Lock on: in any MODE press and hold START/STOP for
2 seconds. The HR lock icon will display.
- To turn HR Lock off: first dry the watch by towel, then repeat the step above.
