It does not operate when powering down in the middle of a dose: when the pump is restarted, it will await a press on the START key to begin the interrupted dose again. Auto-restart is retained while the pump is switched off. When the pump starts running, look for the ! symbol on the display. This ! symbol indicates that the pump is set for auto-restart.
