bObi automatically returns to her charging station when her battery reaches 15% capacity. If bObi is having a hard time finding her station, then you will need to sync it.
To sync the charging station, first flip bObi's power switch OFF. Make sure the charging adapter is plugged into bObi's charging station.
Use the syncing tool that came in bObi’s box to press and hold down the sync button, located inside a pin-sized hole on the back of bObi's charging station. You should hear a clicking sound once you’ve pressed it.
While holding down the sync button with the sync tool, flip bObi’s power switch ON.
bObi will chirp twice to let you know the sync has been successful.
