On the Subject of Maritime Flags
When radio communication fails, signal flags may be the answer.
Identify the flags on the module. Decode a 7-flag callsign followed by a bearing of up to three digits. These are two separate messages.
Look up the callsign on the next page to obtain another bearing. Add both bearings and take the result modulo 360.
Turn the compass so the red needle points in the direction containing this bearing according to the diagram on the left.
