As soon as the magnet starts turning, i.e. as soon as the seed drill

be seen at any time on the display of the calculator by briefly pressing
the ha-key. The display, e. g.: 12.73 , corresponds to 12.73 ha =
127300 m².
7.2 Discontinuing the use

hours no key is actuated, the calculator automatically switches off.
You may, however, switch off your calculator manually by pressing
the
-key and the -key simultaneously for 5 seconds. The
display then reads
[STOP]
