“Medtronic has received a small number of reports regarding users that have accidentally programmed the pump to deliver the maximum bolus amount. This can occur as all insulin delivery programmed through the Main Menu will allow the down arrow button to scroll from 0.0 units to the programmed maximum insulin dose.
Because accidental button pressing errors may occur, it is important that you always confirm the insulin dose flashing on the display is correct before pressing ACT to start delivery.”
