7.2 DIAGNOSIS

7.2.1 TEST MODE

(Outline of Test Mode for Service)

Step 1 Starting operation: Ground test point SERVICE, then press the RESET switch. The system outputs "TEST MODE."

Step 2 Confirmation of guidance: The system plays back in order of the numbers shown above every time the [+] key is pressed. Pressing the [-] key is invalid. Sound volume can

be switched with the LEVEL key as with in normal use.

Step 3 Confirmation 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 4 Confirmation of registration: Press the MODE key for more than two seconds. The system outputs "Input name." Speak a word. The system outputs the word, then

generates a [Peep peep]. When four words are registered, the system outputs "Naming is complete," and you may proceed to the next step.

Step 5 Confirmation of recognition: Press the MODE key for less than two seconds. The system outputs "Make your request." Speak the words registered in Step 4. The systems

outputs "Thank you" (if recognition is successful), then generates [Peep peep]. You may repeat this as many times as you wish. When registration/recognition is failed:

[Bee-ee peep], changing from low to high pitch, will be generated, instead of the [Peep peep] in Step 4 and "Thank you" and [Peep peep] in Step 5. Repeat Steps 4 and 5.

Step 6 End: When Step 4 is completed, press the MODE key for more than two seconds. The system outputs "Test is finished." If the MODE key is pressed for less than two

seconds, the system outputs "TEST MODE" and returns to Step 2.

To return to normal operation: Open Pin 1, then press the RESET switch.
