Select Settings > Features > Shoes/bikes > Bike 1/2/3 > Wheel

Wheel size settings are a prerequisite for correct cycling information. There are two ways of determining the wheel size of your bike:

Method 1

Look for the diameter in inches or in ETRTO printed on the wheel. Match it to the wheel size in millimeters in the right column of the chart.

Method 2

Measure the wheel manually for the most accurate result.

Use the valve to mark the point where the wheel touches the ground. Draw a line on the ground to mark that point. Move your bike forward on a flat surface for one complete rotation. The tire should be perpendicular to the ground. Draw another line on the ground at the valve to mark a full rotation. Measure the distance between the two lines.

Subtract 4 mm to account for your weight on the bike to get your wheel circumference. Enter this value in the cycling computer.

To activate the G3/G5 GPS sensor in your training computer, select Settings > Features > G3 > On. Teach new sensor? is displayed.

To return to time mode, press and hold the STOP button.

The training computer converts measured air pressure into an altitude reading. Change the settings of 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.

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.

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.

** This is a sum of 2 or more exercises; maximum duration of a single exercise is 99 h 59 min 59 s. The maximum recording time can be shorter, if you record a large number of short exercises.

Recording doesn't automatically stop when the memory becomes full. Therefore, exercise time may be longer than recording time.

Select Settings > Features > RR data > On / Off

The RR data recording function measures and records heartbeat variations within one millisecond resolution. This enables the analysis (accuracy 1ms) of heart rate variability (HRV) using the software. The RR data function consumes the memory of the training computer, therefore when setting the function, the remaining recording time is shown on the lower row of the display.

Select Settings > Features > Speed view > km/h (mph) or min/km (min/mi)

Set the automatic lap recording

Select Settings > Features > A.Lap > On > set the lap distance

The training computer will automatically record laps. Choose Off to deactivate.

Define the way to display your heart rate

Select Settings > Features > HR view > HR / HR% / HRR%

Define the sport zones in the training computer

Select Settings > Features > Sport zones > Sport zone low limit

Set the lower limit of sport zone 1 by pressing UP or DOWN. Then press OK. Set the lower limits of each sport zone in the same way. When setting the lower limit, the upper limit of the previous zone is set automatically.

Press and hold LIGHT to switch between sport zone views: HR% (percentage of maximum heart rate) or BPM (beats per minute) or HRR% (percentage of heart rate reserve).

To set the sound level

Select Settings > General > Sound > Volume > On / Off

Volume settings control button sounds and activity sounds during exercise. This does not affect the watch or target zone alarms (TZ Alarm).

To set the target zone alarm on/off

Select Settings > General > Sound > TZ Alarm > On / Off

The target zone alarm will go off, and the limits will flash when you are outside the target zone. If the volume is turned off, but TZ Alarm is still on, the TZ Alarm will still function.

Define keylock settings

Select Settings > General > Keylock > Manual / Automatic

Keylock prevents accidental button presses.
