cvending Posted June 27, 2014 Share Posted June 27, 2014 Today I visited an account with a National 167 Snack machine. When I get there is a post-it note on the machine for refunds. I explained that the SureVend will prevent you from losing money. Several of them say they have seen it steal money. I press the "Diagnostic" button on the service keypad and the display reads "SV.CAL". I assume that means the SureVend needs calibrated. I can't find anywhere in the manual on how to proceed. Anyone ever have anything like this happen? Thanks for your input. Link to comment Share on other sites More sharing options...
