Now leave the office and head to the Control Room. Word to the wise? Be sure to save because you'll never know if some guards will be lurking around the hallways. If you get caught you automatically lose all the progress you've made and will have to have a do-over. Once you're there, the first thing you should try to do is fix the clock in the set. Use the clock hand you got from winning the Hanoi Puzzle and attach it to the Eleven o'clock. A key will be your reward.
Next, head to the Control Room and key it in the password that you've decoded. Then use the key from the clock on the High Voltage box on the wall to turn it on. Afterwards, get the Security Tape on the shelf and then use the Cassette Player here to play the Bomber's recorded message from the tape recorder. Even with the help of the audio control, you still can't figure out who the saboteur is. So that's a dud but a necessary dud. The white board will have a message that says: Light reveals what is hidden in the darkness - but you must first unlock the powers of the light.
For a bonus, you can play with the sound effects switchboard but it really won't have any effect on the game, merely for your personal enjoyment. So we've done all we can do and we should be heading out back to the ground floor. Remember that locked door by the wall and the catwalk control? You can open it now with the same key you got from the clock. So we should turn the generator on now. The levers should be placed accordingly: top one, middle one, top one, bottom to far right. How did we do this? There is a poster there that shows how to move the levers. Each lever will change the positions of the other levers so this is the only method that will work. After you activate the generator, the gears will start turning.
