Hamilton ACW stuff?

I would include the link to Hamilton trouble shooting if they had one.   You know like if they had a FAQ that was useful to trouble shoot the device they sold?

• ACW5 “Car Wash Busy”
• ACW general information
• ACW general documents
• ACW display says “Memory Data Altered”
• Hamilton ACW 5 “Card Unreadable” or something like that.
