This is only true with SR on. If it is off the screen will not come up. When this question pops up I always point people out to this step-by-step guide that was made for the K100D:
K100D (Super) Pictorial guide to using manual lenses [imgs] [Page 1]: Pentax SLR Talk Forum: Digital Photography Review
Naturally there will be some differences between this and the K200D but i figure anyone who buys a DSLR will be able to figure those differences out on their own. Good luck!
