Using the chronograph to measure time
the chronograph is operated by means of buttons a and B. the measurement
starts when button a is pressed once. pressing this button again stops the
measurement. the measurement is resumed by pressing button a once more.
this allows you to add up and record the cumulative time. Button B resets the
hands of the chronograph to zero.
