If anyone would like to contribute other manuals we'd be happy to host them. We'd also like to see articles on how-to-use, troubleshooting, repair, etc.

Many of the so-called Instruction manuals contain more than just operating instructions. They may also have theory of operation, adjustments, parts lists, schematic diagrams, component layouts, and other maintenance tips. Download or view the manual and see if it has the information you require.

Neil WA6KLA once commented to me that when you seek information on most any Cushman service monitor you need to keep in mind Cushman changed the hardware and the matching manual from time to time. You need to know the serial number of your instrument versus what serial number series the manual covers.
