Use the E key to leave the programming mode and return to the display mode. Your entries will be saved.
On leaving the programming mode, all the presets are recalculated because not all the values may be attained with a prescaler value of >1. Therefore, the presets have to be checked and corrected as necessary after saving the presca ler. If no key is pressed for more than 16 seconds in the programming mode, the counter will automatically return to the display mode. In this case, however, no entries will be saved except the last value saved with the E-key.
