Revital Paran that is not an error message. since it starts with the letter"r" it refers to the internal buffer capacity. The "r" stands for "Remaining" and the number is so that you know how many shots you can have in the camera's memory buffer. In case you wanted to shoot, continuously, for example, you'd have room for 17 shots. In 14-bit mode you will see "r15" and "r17" in 12-bit mode if the buffer is empty.

Check the manual exposure control. Manual under and over-exposure can be changed this way in most of the modes.
