3. Browse through the sport profiles with UP/DOWN. You can add more sport profiles to your M430 in the
Polar Flow mobile app or in the Flow web service. You can also define specific settings for each sport
profile, such as create tailored training views.
4. To make sure your training data is accurate, stay in the pre-training mode until M430 has found your
heart rate and GPS satellite signals.
Heart rate: M430 has found your heart rate sensor signal, when your heart rate is shown.
When you're wearing a Polar heart rate sensor that's paired with your M430, the M430
automatically uses the connected sensor to measure your heart rate during training sessions. The
Bluetooth icon on the heart rate symbol indicates that your M430 uses the connected sensor to
measure your heart rate.
GPS: The percentage value shown next to the GPSicon indicates when the GPS is ready. When it
reaches 100 %, OK is displayed, and you are ready to go.
To catch the GPS satellite signals, go outdoors and away from tall buildings and trees. For best GPS
performance, wear M430 on your wrist with the display facing up. Keep it in a horizontal position in
front of you and away from your chest. Keep your arm stationary and raised above the level of your
chest during the search. Stand still and hold the position until M430 has found the satellite signals.
GPS acquisition is fast with the help of assisted GPS (A-GPS). The A-GPS data file is automatically
updated to your M430 when you sync your M430 with the Flow web service via FlowSync software or
with the Flow app. If the A-GPS data file has expired or you haven't synced your M430 yet, more time
may be required for acquiring the current position. For more information, see Assisted GPS (A-GPS).
