System Check mode · The system beeps three times when changing to another mode. · The system beeps once every time a physical address is displayed. · When changing to another mode Blinking "SYS" is displayed. · After completing System Check Displays a physical address. ··Identifies the device. Example: H Physical address (1DIN-TV) Distinguishes from LAN-CHECK. Displays a Diagnostic code. ··Identifies the type of error. Example: Serial No. Diagnostic code Displays a physical address. (Same as the left.) Displays a periodical communications number. ··Displays the time when the error occurred. -- 360 Physical address (CD-CH) Example: 1 -- 02 Serial No. Elapsed time (2 minutes) Displays Diagnostic code. (Same as the left.) 1 -- ------ When there is no physical address: Displays a physical address. The next lowest physical address · When there is no Diagnostic code after completion of System Check 00 The system changes as shown above, as this unit does not include System Check. Displays an auxiliary code. (Same as the left.) Displays a physical address. · When there is no Diagnostic data: 00 1 -- d2 · Displays the details of Diagnosis.
