III. Setup & Functions
Before first use
There are two modes for the smartLAB cadspeed: mode for measurement
of speed and a mode for the measurement of cadence. You can't measure
both at the same time.
To switch mode, you need to remove the battery and reinsert it. The
battery will load again. The LED on the sensor will then indicate in which
mode the device is.
