Question:

What does it mean when the Symphony reads, "invalid card?"

Answer:

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.
