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.

Use the following graphics as a reference to how to interpret semaphore characters.

Rest / Space	Numerals	Error / Attention	A or 1	B or 2
C or 3	D or 4	E or 5	F or 6	G or 7
H or 8	I or 9	J or Letters	K or 0	L
M	N	O	P	Q
R	S	T	U	V
W	X	Y	Z	Cancel / Annul
