As a result of shutting down the system due to a critical issue.
Pulling the battery out before shutting down the device.
Shutting down the device by pressing the on/off button for more than 7 seconds.
The cause for this is that we assume the device might be having pressure issues and we do not want to make it worse by pushing the injector back to the home position which will lead to the dosage in the injector pushing out.
In order to get the injector back to home position, fix the issue that caused this (one of the options detailed above), turn the system back on and off again.
