On the Subject of Semabols

I'm not sure what these symbols are, but I'm pretty sure they have something to do with maritime flags.

The module consists of eight symbols arranged in a regular octagon around six more symbols, as well as eight LEDs on the corners of the outer symbols.

The outer symbols make up a 3×3 cross-section of a 3×3×3 cube made of 3 layers. All possible layers are shown below from a top down view. The cross-section will be along an axis of the cube perpendicular to the layers, and its center symbol will be missing from the outer symbols.

Each pair of symbols with the same LED placement corresponds to a semaphore character with one symbol representing the left flag and the other representing the right. The direction of each flag in the semaphore character is gotten by the position of the symbol in the cross section when viewed from the top, left and front. Each symbol in the cube, except the middle center symbol, corresponds to a letter of the alphabet going in reading order from the topmost to bottommost layer.

Press the inner symbol corresponding to the semaphore pair with the top left LED, then the top right, then bottom left, then bottom right to solve the module. Striking will clear your input, but will not reset the module.
