Nuclear Explosives 101:
Hello and thank you for choosing the Syndicate for your nuclear information needs.
Today's crash course will deal with the operation of a Fusion Class Nanotrasen made Nuclear Device.
First and foremost, DO NOT TOUCH ANYTHING UNTIL THE BOMB IS IN PLACE.
Pressing any button on the compacted bomb will cause it to extend and bolt itself into place.
If this is done to unbolt it one must completely log in which at this time may not be possible.
To make the nuclear device functional:

Place the nuclear device in the designated detonation zone.

Extend and anchor the nuclear device from its interface.

Insert the nuclear authorisation disk into slot.

Type numeric authorisation code into the keypad. This should have been provided. Note: If you make a mistake press R to reset the device.

Press the E button to log onto the device.

You now have activated the device. To deactivate the buttons at anytime for example when you've already prepped the bomb for detonation remove the auth disk OR press the R on the keypad.
Now the bomb CAN ONLY be detonated using the timer. Manual detonation is not an option.
Note: Nanotrasen is a pain in the neck.
Toggle off the SAFETY.
Note: You wouldn't believe how many Syndicate Operatives with doctorates have forgotten this step.
So use the - - and + + to set a det time between 5 seconds and 10 minutes.
Then press the timer toggle button to start the countdown.
Now remove the auth. disk so that the buttons deactivate.
Note: THE BOMB IS STILL SET AND WILL DETONATE
Now before you remove the disk if you need to move the bomb you can:
Toggle off the anchor, move it, and re-anchor.

Good luck. Remember the order:
Disk, Code, Safety, Timer, Disk, RUN!
Intelligence Analysts believe that normal Nanotrasen procedure is for the Captain to secure the nuclear authorisation disk.
Good luck!
