When the Symphony message reads, "invalid card" it could mean that the card in the pump is not the correct program card; the card could be damaged or the card is not inserted correctly.
Unplug the pump and remove the card. Check the card to make sure it is the correct card and also check for damage. Replace if necessary. Make sure the card is inserted in the direction of the arrows and the arrows are visible.
Plug in the pump and press the let-down button and the power button at the same time. Hold for several seconds and release. Try the pump again. If this does not correct the problem, the pump would need to be sent back the rental station for return to Medela.
What should I do if my milk is already flowing when I start pumping?
Use the individual setting and press the "let-down" button to directly use the expression mode.
The button all the way to the left is the on/off button. The knob in the center of the unit controls the suction and speed. The button all the way to the right is the "let down" button. This button interrupts the first phase (stimulation phase) so you can go right to the expression phase without waiting for the 2 minute stimulation phase to end.
The Symphony automatically shuts off after 30 minutes with both battery and electric operation.
