Looking for hints to complete a mission in Cypher 007

On the Mac version, there are three (3) Chapters of ten (10) Missions each with several difficulty levels, Challenge Mode #2 being the toughest to complete.

Has anyone been able to complete Chapter Two Mission #9 (Blofeld's Private Quarters) in Challenge Mode #2?

I have been able to complete all missions but this one.

Would anyone have hints to share?
