If you are maintaining an FA2J, do not read this manual cover-to-cover. Use it strictly as a reference guide for wiring diagrams and error codes. For programming logic, rely on the "Help" file inside the WindLDR software (which is searchable and indexed) rather than the paper manual, as the software help files are updated for modern UI contexts.
