For example: if you have not taken insulin up to 9 hours ago:
This is indicated by a total of 9 diode flash by the same 4 LEDs (2 intervals of the 4 LEDs followed by 1 LED).
15 hours: 15 diode flash by the 4 LEDs (3 intervals of 4 LED + 1 interval of 3 LEDs).
24 hours: 24 diode flash by the 4 LEDs (6 intervals of 4 LED).
More than 24 hours: 3-second lightwave.
>A flash by the outer LED will confirm each new time counting (no need to press the button to check that the timer has started).
DUKADA Trio takes into account that the user might remove the Top Cap for 10 seconds or more without taking insulin. In that case the user can keep the ongoing time counting by pressing the button for 1.5 seconds until the outer LED flashes before mounting the Top Cap.
