Adventist Youth Honors Answer Book/Wigwag Code
In order to send Morse Code via wigwag flag, one must obviously first learn Morse Code. See section a for details. Second, one must know how to transmit dots and dashes with the wigwag flags. The sender holds two flags, one in each hand. The "rest" position is both flags straight up. To send a dot, the flag on the right is lowered straight out to the right and then raised again. To send a dash, the left flag is lowered straight out to the left and then raised again.
