Hi all,
Does anyone know the function of the credit button in setting the odds on a Yamasa Super Planet T pachislo machine?

If I place the machine in reset to change the odds, the level is displayed in the left-most digit of the two-digit payout display and is changed using the reset button.

If I press the credit button, the right digit toggles between 0 and the current odds level. So if I set the odds level to 5, the display reads 50. If I hit the credit button, the payout reads 55. Hit credit again and the display reads 50.

The power supply only has the power, reset key, reset button, and empty-the-hopper switches. It doesn't have slide switches for disabling the reset requirement after a bonus game.

My initial thought was that maybe it disables the credit function, but that wasn't it. Maybe it disables the bonus game reset requirement?

Thanks in advance,
Kirsten
