DIAGNOSIS FUNCTION
Error codes over tuner and connected equipment are displayed on the screen of tuner.

When pressing "1" of TRACK TUNE APS button in LAN check mode, the mode turns to the system check mode, the system performs self diagnosis of connected equipment and displays the results.

The smaller code numbers (physical address) are displayed in order (code No. (physical address), diagnosis code, support code of diagnosis code (object equipment)).

When no error is detected in the system, "00" is displayed. When an error code is detected, up to 6 codes per one system are displayed. Pressing TUNE "UP" or TUNE "DOWN" switches the display. In the system check mode, when pressing "6" of TRACK TUNE APS button the mode returns to LAN check mode.
