exercise, HRV decreases as heart rate and exercise intensity increase. HRV also decreases during
periods of mental stress.
HRV is regulated by the autonomic nervous system. Parasympathetic activity decreases heart rate and
increases HRV, whereas sympathetic activity increases heart rate and decreases HRV.
HRV is used in the Ownzone, OwnIndex, and OwnOptimizer features. It can also be monitored on its
own using the cycling computer. If your HRV changes at a given cycling pace and heart rate, this may
indicate a change in your training load and stress.
R-R Recording
R-R recording rate saves heartbeat intervals, i.e. intervals between successive heartbeats. This
information is also shown as instantaneous heart rate in beats per minute in recorded samples.
When recording every single interval, extra systoles and artefacts can also be seen. We recommend
using contact gel (ECG gel) to optimize contact between your skin and the transmitter. Readings
interpreted as incorrect in the heart rate data can be adjusted and corrected with the Polar ProTrainer
5 software.

Care and Maintenance
Like any electronic device, the Polar cycling computer should be treated with care. The suggestions
below will help you fulfill guarantee obligations and enjoy this product for many years to come.
Caring of Your Product
Detach the transmitter connector from the strap after use. Clean the connector with a mild soap and
water solution. Dry it with a towel. Never use alcohol or any abrasive material (steel wool or cleaning
chemicals).
Rinse the transmitter strap with water after every use. If you use the strap more than three times a
week, wash it at least once every three weeks in a washing machine at 40°C / 104°F. Use a washing
pouch. Do not soak, and use neither detergent with bleach nor fabric softener. Do not dry-clean or
bleach the strap.
Wash the strap before long–term storage, and always after use in pool water with high chlorine content.
Do not spin-dry or iron the strap. Never put the connector in a washing machine or a drier! Dry and
store the strap and the connector separately.
Keep your cycling computer, transmitter and sensors in a cool and dry place. Do not keep them in a
damp environment, in non-breathable material (a plastic bag or a sports bag) nor with conductive
material (a wet towel). The cycling computer, transmitter and sensors are water resistant, and can be
used in rainy weather. To maintain the water resistance, do not wash the cycling computer or the
sensors with a pressure washer or sink them under water. Do not expose to direct sunlight for extended
periods
Keep your cycling computer clean. Clean the cycling computer and sensors with a mild soap and water
solution and rinse them with clean water. Do not immerse them in water. Dry them carefully with a soft
towel. Never use alcohol or any abrasive material such as steel wool or cleaning chemicals.
Avoid hard hits to the cycling computer, speed and cadence sensors, as these may damage the sensor
units.
* Optional sensors.
Service
If your Polar cycling computer requires service during the first two-year guarantee/warranty period, we
recommend that it is carried out by authorized Polar Service Centers only. The warranty does not cover
damage or consequential damage caused by service not authorized by Polar Electro. For further
