Quoted from videobrain:

On TFTC at least, there are two buttons. One moves through the options and the other one makes you go through the list forwards or backwards. Depending on whether you have that second button pushed in or not will decide whether you see audits and adjustments or diagnostics. You get about 10 or so options by default, and the last one will be an option to expand the options, which gives you a lot more in both audits and adjustments and in diagnostics, when you press the start button. The start game button on the front of the cab is my 'enter' button.
From Pinwiki:
The East-A-Just system is very similar to the menu system in Bally/Williams System 11 machines. The control panel is located in the cabinet just inside the coin door. The forward/reverse (green) button is an up/down positional switch and the step (black) button is a momentary switch. To enter the East-A-Just system press the step button. If the green button is in the down position the game will enter the diagnostics menu. If the green button is in the up position the game will enter the audits and adjustments menu. Diagnostics are game dependent so check your game manual for specifics. All games do have a switch test with the diagnostics section that can be used to diagnose switch problems. To exit the Ease-A-Just system hold down the Step button. This will rapidly send you to the last setting and will put the game in attract mode.
