HEART RATE MEASUREMENT

You can measure your heart rate anytime (except in
setting sub-modes).
1. Wear the watch on your wrist and place fingertips
(suggest to use index finger and middle finger) on both
metallic plates to enter Heart Rate Mode. A beep tone
will be heard and "HR" banner will flash to indicate the
watch is detecting heart rate reading. It will take between
6-10 seconds to detect a heart rate reading.
2. If a valid heart rate reading is detected, another
beep tone will be heard and the screen below will be
displayed. Remove your fingers.
