CO sector battery change

Anyone help an idiot figure out how to open the cover to replace the batteries? It's an Atwood 900-1043 unit. Thanks!

Here is the owners manual and a picture from the manual.

Thanks!!! The installers mounted the CO detector to the ceiling and aligned the bracket where it hid and blocked the battery door opening. Had to remove the bracket and then it was easy peasy!
