Initialization (from a card):
From the manual (sic)...
Initialization of the Forte Card circuit board
(Init machine)
1) Open the door of the machine, switch on the game and wait until the message
"Permanent RAM test faliled" appears.
2) Turn the Main Control and hold in this position
3) Enter the serial number of the circuit board with the eight keys
4) Press STAR key (sic) and wait until the message "Machine initialization completed" appears.
'Permanent RAM test failed' appears.
2) Turn the Main Control and hold it in this position.
3) Enter the serial number of the circuit board with the eight keys.
4) Press STAR key and wait until the message 'Machine initialization completed' appears.
5) Release the Main Control, switch off the game and close the door.
6) Switch on the game and wait until the demonstration displays appear.
7) Turn the Main Control, adjust the time. This is the last step of the initialization procedure.
