Acer Aspire ASE360-UA421M Cover Plate Removal

I accidentally placed my digital camera SD card into the wrong slot and it dropped to the bottom of the computer. It is in a space between the front panel and the beginning of the computer chassis, approximately a space of an inch. I can see it at the bottom of the computer. I can remove the left side panel. How do I remove the front cover plate to retrieve the SD card? Thanks for your help.
