This seems to be some kind of picture matching puzzle,
probably stolen off of another module.
Find the picture with matching circular markings.
The grid shown on the bomb (and its markings)
may be a rotation of an image as it is shown below.
Then, find the correct combination of directions using the starting Manhattan
distance between the red dot and the white triangle, and input them
into the module to disarm it. The input sequence will be immediately
submitted on the eleventh press.
If 10 seconds pass with no buttons pressed, submission will be canceled.
* The Manhattan distance is the smallest number of up, down, left or right
steps needed to move between the two points.
