Original Manual With Visuals

Taking only the first condition met, if the number of unsolved modules + needies modulo...

  • 4 is 0, use column D.
  • 3 is 0, use column A.
  • 2 is 0, use column N.
  • 1 is 0, use column G.

Find the warning sign displayed from the tables provided. The intersection of the sign and letter used results in a digit.

Use the row as the first digit of the serial number and the digit obtained from the tables on the previous 2 pages as the column to get 3 digits. Unscrew each bolt when the last seconds digit of the countdown timer is those digits. Each unscrew can be delayed up to 9 timer ticks before the module strikes on the 10th.
