This could be a big problem for you, so this is very important that you pay close attention to the following procedure or things could go very bad for you. First off, you should immediately find the box your camera came in and move it to an area with room on both sides. Carefully look thru the contents of this box, remove the CD disc and warranty papers and place them next to the box and continue until you find a large rectangular object. This rectangular object will be white in color and will have many pages attached to it. It will also have words on the front cover of the object written in black ink that will spell the words "Users Manual". This is the key to your issue.....
Once you have this rectangular object in hand, look for the section on matrix metering. You will see your little box with circle in it. In fact, you'll find many items in your camera's menu are not written in English or Japanese but rather are symbols of the item so as to cross the language barrier.
I hope this helps....
