Help with IGS "Wheel of Fire" machine

[Bass Vegas]

Hello,
I'm new here, hopefully I'm passing this in an appropriate thread. We just recently acquired a new machine in the arcade and we've been having a difficult time getting a password set and a few other parameters on this machine as it's only "line 1, line 2, etc etc and start, payout" buttons soon with touchscreen but no arrows and the touch screen shows the same key name as the physical key. The game is made by IGS and titled Wheel of Fire FA, this is a single player slot machine style kiosk. I would love to find a pdf manual or some instruction on how to program a password and whether "Main Game Level"( is 1-94% I believe) is hard difficulty 94% or 1%... The game is not very user friendly on swing parameters when bought used with no manual. Any help would be greatly appreciated!
