Setting the DISTANCE
If you have a specific number of kilometers that you want
to travel during your workout, use this feature. An alarm
sounds when you reach the specified distance. To set the
distance, take the following steps:
1. When DISTANCE is displayed, press the SELECT
button. The icon stops blinking.
2. Press the CLEAR button to reset the display to zero.
3. Press the SET button to choose the distance that you
want to travel. You can set distance in 0.5 increments
and select up to 99.5 kilometers.
4. Press the SELECT button to start the countdown.
Choosing a Target Heart Rate
Studies show that to achieve the benefits of aerobic exercise, it
is necessary to work out hard enough to raise your heart rate to
a certain minimum level called the “training zone.” Your training
zone depends on your age and level of fitness.
