*HELP* Pentax 645 (Cant Get Manual Mode)

Hi,

I have recently purchased a Pentax 645 camera body only, I also
purchased a AF lens (SMC Pentax-FA 75mm f2. from another source.

I cannot get manual mode whilst shooting (I take the lens off its A
setting of course).

When I press the mode button and press up and down (with the lens off
A) it still
reads (Auto 125, Auto f5.6, Auto P).

I have taken the lens off and tried again still with these results.

Is my new camera broken?

*HELP* Please Anybody
