1. A method of dispensing a compound from a dispenser for a compound-containing container, the dispenser comprising a receiving chamber for a container, at least one push rod displaceable relative to the receiving chamber, a motor for moving the at least one push rod, a control unit comprising a memory module and a data processing module and configured to control the motor, a main switch for activating the motor, an operation selection switch configured to set a selected amount of the compound to be dispensed for one application run in an application run, and a sensor configured to detect movement of the at least one push rod, the method comprising:
selecting the selected amount of the compound via the operation selection switch;
activating the motor via the main switch to displace the at least one push rod and begin dispensing the compound in the application run;
determining, using the sensor, an already dispensed amount of the compound;
calculating, by the data processing module, a missing amount of the compound based on a difference between the selected amount and the already dispensed amount;
storing the missing amount in the memory module when the application run is interrupted; and
upon re-actuation of the main switch, activating the motor to dispense the missing amount stored in the memory module to finish the interrupted application run.
