Oh yes, for your FAQ, here is what to do on the PDA level
1. Explore the top level and obtain all items (build notes, permissions etc)
2. return to the room where you started, ride the platform down to the lower level and explore it. the last room has a platform that will bring up to the top level. After riding to the top level, hit the button to lower it and JUMP off so that you are still on the top level, this way the platform is ready for when you make your run to turn on all systems. The room you are in is the last room you should activate to lower the PDA's power.
3. Return to the room you started in. Hit the switch to activate PDA functions. Run to where the platform should be, and drop down to the next level, do not summon the platofrm and ride it as it takes a lot of time.
4. Run out of the room and stop at where the two sliding platforms are, hit the switch to turn on more things, then ride the platforms to the third switch, then dash into the next room where the platform you sent back down is, ride it Up to the top level and dash to the final switch.
