What do the battery level icons on the LCD panel mean?
The battery level mark shows four states: a full battery means battery level OK; a declining battery means battery level is low and spare batteries should be kept handy; a nearly empty battery means batteries will soon be completely exhausted; and no display means replace the batteries immediately.
