...the speed reading is 00 or there is no speed reading on the
display while cycling?
1.Check the correct position and distance of the speed sensor with the spoke magnet and the wrist receiver.
2.Check that you have set bike 1 or 2 on.
3.If the 00 reading appears irregularly, this may be due to temporary electromagnetic interference in your current surroundings.
4.If the 00 reading is constant, you may have exceeded 2500 riding hours and the battery of the speed sensor needs to be replaced.
5.If you are using the wireless Polar Speed Sensor, check that Power is turned off in the Options mode.
...inaccurate altitude readings?
The influence of a sudden temperature change (i.e., if you go outdoors in the winter) may cause temporarily inaccurate altitude readings. If the readings are constantly inaccurate, it may be caused by dirt blocking the air pressure channels (three openings on the backcover of the receiver). In this case, send the heart rate monitor to a Polar Service Centre.
...the data transfer from receiver to computer was unsuccessful?
1.Check the correct position of the wristwatch receiver with the infrared window of the computer or the optional interface.
2.Check that the surroundings are not too bright. This problem often occurs near windows.
3.Check that there is no obstruction between the infrared windows.
J.TECHNICAL
SPECIFICATIONS
Polar heart rate monitor is designed to indicate the level of physiological strain and intensity in sports and exercise. Polar S720i/S710i also measures altitude and temperature in cycling. No other use is intended or implied. The altitude and temperature functions are not designed to be exclusive measuring equipment in aviation, climbing sports, water sports or their equivalent. Heart rate is displayed as number of heartbeats per minute (bpm).
