Select Settings > Features > Altitude > Calibrate > set the altitude of current location
If the altitude of your location differs significantly from the displayed altitude value Calibrate to xx? is displayed.
Yes: Altitude calibrated to xx is displayed.
No: Altitude calibration canceled is displayed.
Calibrate the altitude to ensure it remains accurate. Set the reference altitude whenever a reliable reference, such as a peak or a topographic map, is available or when at sea level.
Calibrating the Altitude Automatically
Select Settings > Features > Altitude > AutoCalib > On / Off
By using the altitude Automatic Calibration option, you can adjust the starting elevation to be set always the same in the beginning of the exercise. Calibrate the elevation manually and turn the Automatic Calibration (AutoCalib) on. From now on, this elevation will be always used as the base elevation in the beginning or the exercise, when automatic altitude calibration is in use. Also, if the Automatic Calibration is turned on and you calibrate the cycling computer manually, this new value will be used as a new starting elevation for the Automatic Calibration option.
If the elevation or air pressure changes significantly, you are prompted to confirm the change. If you change the elevation, Altitude calibrated to xx m/ft indicates that calibration has succeeded. If Altitude calibration failed is displayed,
You can also set the elevation for the Automatic Calibration also by using the Polar ProTrainer 5 software. For more information see software help.
Elect this option if you train in the same environment. This way, altitude values are always correct.If the sport profile of the exercise includes automatic calibration, altitude measurement always begins at this elevation regardless of the general elevation settings.
Recording Rate
Select Settings > Features > Rec.rate > 1 / 5 / 15 / 60 sec
The cycling computer can store your heart rate, speed, cadence, power and altitude in 1, 5, 15 or 60 second intervals. A longer interval gives you more recording time, while a shorter interval allows you to record more heart and other data. This enables accurate data analysis using the Polar ProTrainer 5 software.
A shorter recording rate consumes the memory of the cycling computer more rapidly. The remaining recording time is displayed on the lower row when setting the rate. Default recording rate is 5 seconds.
When less than 30 minutes of maximum recording time is left, the recording rate changes automatically to longer recording time (1s > 5s > 15s > 60s). This will maximize recording time to record exercise data. When the session ends, the current recording rate will be used in the next training session.
The following table shows the maximum recording times for each recording rate. The maximum recording time can be shorter, if you record a large number of short exercises.
Recording rate will change when less than 30 minutes of recording time is left. Memory low is displayed 60 minutes before the memory runs out.
