Solution found elsewhere suggested removing the batteries and unplugging the A/C adapter for 10 minutes. (I waited 30). Reinstall batteries and reattach A/C adapter. Buttons worked to get to the erase memory option, which I did. Infoglobe is now functioning properly. This is also the instructions for clearing the "eeprom error" readout that many infoglobes exhibit after a power surge.
