How do you cancel debug mode?

I bought a K10D a few years ago. Came in Debug mode.

Being in debug mode doesn't bother me, or seem to affect the use of the camera, but just in case I want to, how do I get rid of debug mode please?

Doe this link help?

Hmm...link doesn't seem to work, and I can't edit my previous post...

Thanks very much Ian. Took me off down an interesting avenue as (a) my K10D is on v1.30, and (b) I had no idea how to use debug mode for af adjustment, which is my only real interest.
