HOW THE HEART RATE MONITOR HELPS YOU
1
A heart rate monitor is the most important tool in
cardiovascular health and an ideal training partner. It enables 2
you to see and monitor results. This helps you assess your

past performance, maximize your workout and adapt your
4
future exercise program to achieve your desired goals in a
safer and more effective way.

Different activities exercise the body in different ways
and help you to achieve a variety of fitness goals. To
accommodate this, the exercise profile can be set to suit
different exercise activities. For example, if you are running,
your exercise profile settings are likely to differ from those
you would use when undertaking a weight training activity.

limit you have surpassed.

CALIBRATION AND SPEED

CALIBRATION

Before using the speed and distance function, you need to
calibrate for both running and walking. You do this by entering
a pre-set distance and using the watch to determine a rough
estimate of your speed (for both running and walking). This
is called the real calibration.
To set real calibration:
1. Make sure the transmission between the watch and
chest belt is well connected.
2. Press MODE to enter TRAIN mode.
3. Press and hold SET to enter setting mode.
4. Press ST / SP / + or MEM / - to select calibration (CALI)
and press SET to confirm.
5. Press ST / SP / + or MEM / - to select walking or running.
You must do both walking and running separately. The

• The speed and distance function is only for running or

• When calibrating running, for a more accurate calibration
please run below 15km/h (or 3 steps per second).
• The watch will show the estimated distance completed
during calibration. If the final estimate is 20% over or
under the set distance, we suggest recalibration.
