SoFlow SO4 2nd Gen Mode D'emploi Original page 17

When you want to close the battery compartment, fold the cover back in. The closing
mechanism will automatically engage.
WARNING!
Do not close the compartment if there is no battery in it. Otherwise, the compartment cannot be opened again.
If this still happens, you must lift the cover pad at the marked location so that you can
loosen the two screws located underneath.
