K200 white balance

Hi all,
I have just bought a s.hand K200. I want to try and adjust the white balance. The book says, press the FN button, select AWB, use menu to select. With camera switched on if I press FN I get the menu but the Drive Mode, ISO and Flash arrows are lit but not the AWB arrow. Pressing the 'LEFT' arrow has now effect.
Any ideas. I must be doing something wrong but what.

Cheers
Graham

Could be it's already set to auto.

Look in the Custom menu. Don't know about the K200, but on my K20D it's item 12, but in any event it'll be called something similar - WB Adjustable Range.

Toggle Auto off, then try the FN button again.

Hi
I might be that you are in green mode try moving the dial to av
And then try that it's being a long time since I had a k20

Ahhh thanks Neil, that got it. Didn't say you had to be in AV mode to do it in the book.
Thanks everyone.
