Hi i just bought a Barcrest Black and White Special fruit machine today,i have no idea how to work it.
When i turn it on it says BLAC 1.6 then it stays on AL24 A7 on the LED display,is it anything to do with the hopper being empty?
Also the "status LED" inside flashes red several times then green for a second then back to red.
The person i bought it from says it doesn't require a refill key as it has been set up to use a button instead,located in the box underneath.
I downloaded the MPU5 Genesis Manual and the Barcrest Single Hopper PDF but still have no idea.
I pressed the test button inside ( can only find 1 ) and the dump hopper button and stuff like start / hold etc now the LED display is blank after it flashes BLAC 1.6 for a second after i turn it on and the reels will only spin round if the door is open ( when i turn the mains on ) as it's starting up.
Does this mean it's in some sort of test mode?

Thanks,any help would be much appreciated.
