Some tips:
Open door 'C' and toggle refill then press '0' to fill the cashbox to max £320
Untoggle door 'C' and refill, then after the machine resets toggle door 'C' and press the TEST button toggle through the menu using 'Space bar' untill you reach % change and increase it to 90%. (Press Excahnge to select)
You can also increase the Cashbox and Reserve to there Max if the machine has has been Reset from the Config' menu.
With practice you'll get the hang of the machine and at 90% it plays alot 'Friendlier'.
My fav Club machine from back in the day. Glad to see it in 1024 format running under MFME.
