Approach the bomb and press the key/button displayed on the screen to remove the metal casing and reveal the interactive panel. Use the Cryptographic Sequencer here, and get ready to guess the three passwords shown in the above screenshot. To guess each of the passwords, you have a limited amount of time (21 seconds for the first one, 19 for the second and 17 for the third). The good news is that you do not have to choose from among multiple possible combinations and only manipulate with the keys/triggers to lock the device in the only possible position.
