On the Subject of Sonic the Hedgehog

Sonic the Hedgehog was a popular 16 bit video game from 1991. What it's doing here on a bomb over 25 years later is anybody's guess...

See Appendix SN72 for a phonetic guide to each sound.
See Appendix SN73 for image references.

The module consists of a television screen with an on (top) and off (bottom) button, four "TV monitor" buttons and a Start button.

To disarm the module, you will need to progress through three levels of play, identifying the correct TV monitor to press in response to the given picture.

Each TV monitor will play a sound. You may listen to the sounds as many times as you like prior to starting the game.

IT IS CRITICAL THAT YOU IDENTIFY THE SOUNDS BEFORE PRESSING THE START BUTTON: ONCE THE GAME HAS BEEN STARTED, YOU WILL NO LONGER BE ABLE TO PLAY THEM.

Pressing the incorrect TV monitor will result in the module being reset and new sounds being generated.

Once you are sure of the sounds, press the Start button to begin and refer to the tables below. It is advised that the television screen is switched on.

To use the tables, identify which picture has been displayed and work from left to right. If the condition at the top of the table is met, press the relevant TV monitor.
