Abstract: The present invention relates to an electronic injection device wherein an electronic circuit is designed to work in two alternative modes: an air shot mode and a dose injection mode. When working in the air shot mode a small predetermined air shot dose is pressed out from the ampoule when the injection button is actuated. When working in the injection mode, a dose set by operation of the dose setting means is injected by operation of the injection button. The electronic injection device is normally working in the air shot mode but shifts to work in the dose injection mode when it receives a signal indicating that the dose setting means has been operated. The circuit returns to its air shot mode when receiving a signal indicating that the set dose has been injected. This signal can originate either from a switch indicating that the protection cap is mounted or from a switch indicating that the injection button has been pressed.
