ISO settings on 1DIII


I just bought a used 1DIII. The English manual is missing, but the camera is in excellent shape. This is my first 1D body ever.

I cannot lower the 1SO under 200.  The first thing I did when I got the camera was to reset all settings to factory default. I tried custom function I-3, played with it, deactivated it, registered the Lowest ISO speed to "L", clicked "apply"... Tried everything and still ISO will not go lower than 200.

Am I missing something?

Or is the software in the camera corrupted?

Please!!! help!!!

Many thanks,
