Hello again...trying to help local club set up a six selection Vendo Coke machine (Model 324185024 971117, Serial # 599847). Thought would use three button programming like my other machines but apparently does not. I get an error code when entering the service mode. That is followed by these codes...in no particular order: CPO, Chgr (I think), and IC (input chute). I also got the message that there are no errors when pursuing error codes a time or two...I can't get to Prc...don't know how to clear error code(s). The manual does not include programming info.
From info I have, it looks like this machine is programmed using four selection buttons. Any info would be most helpful. Everything else seems to work fine...bills and change register, it gives change, and all six selections vend.
