45、2 7.2 DIAGNOSIS 7.2.1 TEST MODE (Outline of Test Mode for Service) Step 1Starting operation: Ground test point SERVICE, then press the RESET switch. The system outputs TEST MODE. Step 2Confirmation of guidance: The system plays back in order of the numbers shown above every time the + key is pressed

46、. Pressing the - key is invalid. Sound volume can be switched with the LEVEL key as with in normal use. Step 3Confirmation of IP-BUS connection: When the MODE key is pressed for less than two seconds, the system informs of the result of communication to confirm whether connection of IP-BUS is normal or not. The system answers either IP-BUS is OK or IP-BUS is NO GOOD. If the main set is not connected, the system generates a Peep. Step 4Confirmation of registration: Press the MODE key for more than two seconds. The system outputs Input name. Speak a word. The system outputs the
