Q1 : Why doesn't the terminal start when I insert a coin?

Start the Wangan Terminal by touching the touch panel. You don't need coins for anything on the Terminal other than buying a Banapassport Card. (Coins will be refunded right away on all screens other than the Banapassport Card Purchase Screen.)

Q2 : There is something like a clock on the Title Screen. What's it used for?

This displays the internal clock. Use it as a reference when earning "Date Titles" that depend on the date.

Q3 : "Rev *.**" is displayed on the Title Screen, but what is it used for?

This displays the software version running on the machine.
