I wouldn't worry about it because if you have it set to run the pump 24/7 and have an airstone you should be fine. I also have an Aerogarden Pro 100.
Here are the instructions from the Aerogarden web site:
you will need to perform a "factory reset", a simple procedure that will usually restore the AeroGardens ability to hold its settings.
AeroGarden Classic or Deluxe (7-Pod) Factory Reset
1. UNPLUG the AeroGarden.
2. Remove the Bowl and set aside, remove the Lamp Hood, and turn the AeroGarden upside down on its side.
3. Open the little door on the bottom of the AeroGarden, and remove the battery.
4. Plug the AeroGarden back in.
5. Put the battery back in.
6. The AeroGarden is now reset, and will maintain its settings.
Note: a limited number of later-model Classic AeroGardens have an internal circuit that maintains its settings without a battery. If you have a Classic AeroGarden that has a battery compartment without a battery, follow the procedure for the Factory Reset below:
AeroGarden Pro Series (7-Pod) Factory Reset
1. Choose a plant selection for anything except Strawberries.
2. Press and hold the Select button for about 5 seconds, until the selection lights begin to circle around. The grow lights will also go off and come back on.
3. IMMEDIATELY release the Select button when this cycle starts to happen, and then press and quickly release the Reset button.
4. The plant selection will now revert to Tomatoes/Peppers and the Add Nutrient light will flash three times.
5. The AeroGarden is now reset, the pump will start running, and it will maintain its settings.
Occasionally, especially if the Garden was not plugged into a surge protector, an internal fuse will blow, particularly if the garden experienced a power surge such as during an electrical storm. If the factory reset does not restore your settings, please contact Customer Service at 1-800-476-9669.
