Altitude is measured with an atmospheric air pressure sensor. Altitude is shown as ascended and descended meters/feet and uphill/downhill steepness in percentages and grades.

To help you train safely and effectively, the training computer determines your heart rate target zone limits automatically according to your age-based maximum heart rate (220 minus age). The limits are determined either in beats per minute (bpm), as a percentage (%) of your maximum heart rate, or as a heart rate reserve (% HRR). See also Maximal oxygen uptake (VO2max) and Manual target zone.

Heart rate is the measurement of the work your heart does. Heart rate can be expressed as the number of beats per minute or as percentage of your maximum heart rate. Heart rate can also be expressed as a percentage of your heart rate reserve, meaning the difference between your resting heart rate and maximum heart rate (HRR = HRmax - HRrest). In Polar software or during strength training, heart rate can be displayed as a graphical trend.

You can define your target zones for a training session based on heart rate to help define the right intensity. When you are out of the preset zones, the training computer will give a visual and audible alarm.

The highest number of heart beats per minute (bpm) during maximum physical exertion. For a rough estimate of your maximum heart rate, subtract your age from 220. HRmax is a useful tool for determining the intensity of training as intensity zones can be defined using HRmax. Some Polar products define maximum heart rate during the Polar Fitness Test, see also HRmax (Polar Fitness Test -based).

This feature enables you to define the target zone as you want and is suitable for your training. You can set the target zone for your training as beats per minute (bpm), as a percentage of your maximum heart rate, or as a percentage of your heart rate reserve (HRR%).

Polar OwnCal calculates the number of kilocalories expended during training. This feature allows you to follow the kilocalories expended during one training session and cumulative kilocalories expended during several training sessions. Some Polar products also estimate the fat-burning percentage (fat% on display), that is, kilocalories expended from fat during a workout which is expressed as a percentage of the total kilocalories burned.

Coded heart rate transmission automatically locks in a code to transmit your heart rate to the training computer. The training computer picks up your heart rate from your transmitter only. Coding significantly reduces interference from other training computers. The 2.4 GHz W.I.N.D transmission is disturbance-free from other electronic devices.

Polar OwnZone® determines your personal heart rate limits for a training session. Depending on the day and time, your physical state may vary, for instance, if you are stressed or tired, or if you are not fully recovered from your latest training session, Polar can determine that information from your heart rate and guide you to your ideal training zone for that moment.

This feature is available in Polar software. When you transfer training results from your training computer to polarpersonaltrainer.com, you can follow your training load and recovery in the training diary. Continuous monitoring of training load and recovery will help you recognize personal limits, avoid over- or undertraining, and adjust training intensity and duration according to your daily and weekly targets

You can define settings up to two to three bikes in your training computer. When you start training, you can select the bike with the correct settings for that particular training session.

Your cycling cadence stands for your pedaling rate in revolutions per minute (rpm). Cadence is the central factor in improving cycling performance. A higher cadence reduces the force needed for each pedal stroke, and thus improves overall performance. Running cadence measures how many times your either right or left foot hits the ground in one minute. Running cadence is measured as steps per minute. With this feature you can sharpen your cadence and make your ground contact time shorter. This will help you to find a balance between leg power and leg speed.

By activating Autostart/autostop feature, the cycling computer starts and stops training recording automatically when you start or stop pedaling.

You can define settings up to two to three bikes in your training computer. When you start training, you can select the bike with the correct settings for that particular training session.

Distance (km, mi) can be set and measured in several ways. Training distance tells you the distance traveled during a training session. Trip distance tells you the distance from the latest trip reset. Lap distance tells you the distance of one lap. Total distance is the distance accumulated since the last reset. Odometer tells you the cumulative distance which you cannot reset.

Totals includes your training data starting from the last reset enabling you to follow your long-term training.

Weekly history gathers your weekly training data. By selecting a week, you can review your training data for the week.

Automatic display scroll enables you to alternate between displays automatically during training without a need to remove hands from handle bars. Activating automatic display scroll improves riding safety and comfort.

With this feature you can set your training computer to take laps based on preset distance, for example, every 1 km/mi.

This feature points out graphically on the display the zone you are in during a training session helping you to stay on the desired intensity zone.

Use timers, for example, as a training tool in interval training to tell you when to switch from a harder to a lighter period and vice versa. The timers can be time- or distance- based.

You can set reminders to alarm you of different tasks or training sessions, for instance, reminding you to drink during a training session.

ZonePointer is a visible and moving symbol on the training computer display indicating whether you are inside the pre-set target zone. This feature helps you to reach the desired intensity/pace/speed/cadence targets.
