Payout Settings in Sea Story machine

[willypt]

Hi enthusiasts!
I've just acquisitioned a Sea Story with Taiko no Tatsujin and having lots of fun!

During tinkering, I found an interesting button in the back of the machine. Google Translating it shows "Payout Settings" which is very interesting.
Clicking / flicking on it doesn't do anything though.

I've attached picture to clearly show it.

1. Does anyone know what does it do?
2. Does anyone know how to configure things such as date in the machine? Any documented settings usually for pachinko machines?

Thanks!
