Precautions
The Polar cycling computer displays your performance indicators. It indicates the level of physiological
strain and intensity during exercise. It also measures speed and distance when cycling with a Polar CS
speed sensor W.I.N.D. The Polar CS cadence sensor W.I.N.D. is designed to measure cadence when
cycling. The Polar Power Output Sensor is designed to measure power output when cycling. No other use
is intended or implied.
The Polar cycling computer should not be used for obtaining environmental measurements that require
professional or industrial precision. Furthermore, the device should not be used to obtain measurements
when engaged in airborne or underwater activities.
Interference During Exercise
Disturbance may occur near microwave ovens and computers. Also WLAN base stations may cause
interference when exercising with CS500. To avoid erratic reading or misbehaviors, move away from
possible sources of disturbance.
