Polar Electro M450 User Manual page 38

If you have set the GPS function on in this sport profile and/or a compatible Bluetooth® Smart sensor in
use, M450 will automatically start searching for the signals.
Stay in the pre-training mode until M450 has found the GPS and sensor signals and your
heart rate to make sure your training data is accurate. To catch the GPS satellite signals, go
outdoors and away from tall buildings and trees. Keep your M450 still with the display facing upwards
during the search. Hold the position until M450 has found the satellite signals.
Finding GPS satelllite signals is faster with the help of assisted GPS (A-GPS). The A-GPS data file is
automatically updated to your M450 when you sync your M450 with the Flow web service via the
FlowSync software. If the A-GPS data file has expired or you haven't synced your M450 yet, more time
may be needed for finding the satellite signals. For more information, see Assisted GPS (A-GPS).
3. When M450 has found all the signals, press START. Recording started is displayed and you
can start training.
Heart rate: M450 has found your heart rate sensor signal, when your heart rate is shown.
GPS: The percentage value shown next to the GPS icon indicates when the GPS is ready. When it reaches
100 %, OK is displayed.
Cycling sensors: OK is shown next to the bike icon when M450 has found the sensor signals. If you
have linked sensors to more than one bike, you'll see a number next to the bike icon indicating the bike
in use. M450 chooses the bike to which the nearest sensor is linked.
