Thereafter, the bell sounds every 45 minutes to indicate the end of consecutive periods, except immediately after the fourth period when it sounds after 30 minutes to indicate that the lunch break is over. When the last period is over, LED2 glows to indicate that the bell circuit should now be switched off manually.
