Meanings of symbols - Cell Phones

I have questions about the symbols on our new LG GB255g (Madison). The manual gives no picture of the symbols, and LG Canada's tech support line told me, "If it isn't in the manual, I can't tell you." While some symbols are pretty obvious, (signal strength, Bluetooth), there are others which are not obvious, and I am surprised there isn't better access to LG's manuals.
