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
Speed sensor. The Polar Cadence Sensor is designed to measure cadence 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.
