On the Subject of Semaphore

This module demands attention from the sea - unlucky for you the bomb’s bone dry.

See the next page for semaphore reference.

  • A semaphore module will present with a previous button, a next button, an OK button and a semaphore indicator.
  • Use the previous and next buttons to navigate through the semaphore sequence, starting from the left-most semaphore character to the right-most semaphore character.
  • The semaphore sequence will contain some characters from the serial number on the bomb, but also includes one other character not present in the serial number.
  • Navigate to the one and only character that is missing from the serial number, and then press the OK button.
  • Control characters, such as ‘Numerals’, ‘Letters’, ‘Error’, ‘Rest’ and ‘Cancel’ are not considered as a valid answer.

Semaphore Reference

Numbers are signalled by first signalling ‘Numerals’, then the numbers. Similarly, letters are signalled by first signalling ‘Letters’, then the letters.
