Thanks much for this answer, but the manual only names some of the symbols, leaving others nameless. The manual does not describe the function of any of the icons.
There is an icon for resolution, but when I activate it, it only shows a column of 5 boxes with numbers in them, all the way from 5M at the top to 0.8 M at the bottom.
For resolution, I was expecting something like 1280 x 1024
