the first one is for hardware and software options and cabinet options,by clicking it down before you start a game the options come on where you can change options,such as softdip where if the game has blood you can add it, language select free credit,get rid of how to play option,change the level it all depends on the game,hardware is to test if all buttons work, and it also has time change and book keeping,no 2 to 6 are to do with communication? no 7 is freeplay no 8 as you know is pause,one slot is great as you have the flipswitch too,to change from stereo to mono if your cab cant hack it <IMG SRC="smilies/smile.gif" border="0">
