Need help with Premier Crane claw machine manual

[KLOV]

Does anyone have a Maxtrol MAX-3700 manual? They are used in claw machines. I got a manual with the unit I bought used, but I can't seem to get it to change the cost per play settings, so I think something might be off. The claw machine seems to work OK, I'd just like to make it free to play since I have it setup in my garage.
