"No. 0: ANALOG test mode" will be selected just after
entering the test program mode.
Wordclock source is INTERNAL 96 kHz.
"Analog test mode" will always be selected when none of
the "Memory", "LED", "Switch", "Encoder" or "Digital I/O"
test is being conducted.
4. Selection of test item, executing procedure and
indication of results
4-1. Turn the [ASSIGN 1] encoder to select a test item.
LEDs around the [ASSIGN 1] encoder light to
indicate which test is selected. Refer to Fig. 3 for
correspondence between LEDs and test items.
4-2. Turn the [ASSIGN 1] encoder to select a test item and
then press the [ASSIGN 1] encoder to execute the test.
4-3. The LEDs around the [ASSIGN 2] encoder will indicate
the test result. (Lighting: OK, Not lighting: NG,
Blinking: Not tested (No.0: Analog test mode))
