What is this.....?

[Harleybum]

Hi guys! Just got the Sinbad Adventure delivered today. Runs fine and trying to learn everything about it. Learned about the "Stats" and how to set the realtime clock/date.
I found the 3 position slide control for the volume. There are 2 2-position slide switches (both set to the right) next to the reset/payout button. Also in the upper right hand corned by the key switch is some black plastic things.Also in the area is a hinged black plastic widget. Pictures are included.Thanks for any/all help

the 2 switches to the right will keep it from spitting out all tokens and it won't require a full reset after bonus.

the plastic tabs on both boxes are for palour use, nothing we can mess with.

I opened one up once and there was nothing behind it.

I remember reading somewhere on here that the plastic things were a way to determine how many times the machine was serviced or something like that. I guess they were supposed to break them off each time.

black thingys look to be new seals for the motherboard cover?
