For what are those switches ???

[ollium]

There are some switches & buttons in my Sammy Pachislo...but i don't know for what they are
And how do i handle it ?
Here are some photos with the marked switches/buttons...sorry for the bad quality

The first appears to be the button to press for adjusting 'odds' during a reset. (You'll find those steps if you do a search).

The second photo appears to be a three position volume switch. These are notorious for having the option of loud, LOUD, and DEAFENING, which is why many of us opt for installing aftermarket volume controls.

The last photos are switches on the power supply, and you'll have to play with those to find what they do. I'm betting one dumps the tokens from the hopper while it is pressed, the other you've circled is the reset lock. If you do not have a key, there is an easy fix (install a switch instead).
