the altimeter in the Altitude menu. You can calibrate the altimeter manually or automatically.
Set the altitude function on or off
Select Settings > Features > Altitude > On / Off
Calibrating the Altitude Manually
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. The last altitude value stored in the training
computer’s memory is applied.
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
When automatic calibration is on, the last altitude value stored in the training computer’s memory is
applied when exercising. This feature is especially useful if you always start a session in the same
environment. If automatic calibration fails, you are not in the usual environment and will need to
calibrate the altitude manually.
Altitude calibrated to xx m/ft indicates that calibration has succeeded. If Altitude calibration failed is
displayed, re-calibrate the altitude.
Recording Rate
Select Settings > Features > Rec.rate > 1 / 2 / 5 / 15 / 60 sec
The training computer can store your heart rate, speed/pace,* and altitude in 1, 2, 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 software.
A shorter recording rate consumes the memory of the training 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 > 2s > 5s > 15s > 60s). This will maximize the time to
record exercise data. When the session ends, the current recording rate remains as default.
The following table shows the maximum recording times for each recording rate. Note that recording
rate might change when there is less than 30 minutes of recording time left.
