DESCRIPTION

Diagnosis function consists of the "Self-Diagnosis" mode performed automatically and the "Confirmation/Adjustment" mode operated manually.
"Self-Diagnosis" mode checks for connections between the units constituting this system, analyzes each individual unit at the same time, and displays the results on the LCD screen.
"Confirmation/Adjustment" mode is used to perform trouble diagnosis that requires operation and judgment by an operator (trouble that cannot be automatically judged by the system), to check/change the set value, and to display the error history of the AV control unit.
