While "0" is displayed on the 7-segment screen, operate each
VR to the left.
While "1" is displayed, operate each one to the right.
Upon completion of check, moving to the next VR takes place
automatically.
When the last VR has been operated and the check is
successfully concluded, moving to the next step takes place
automatically.
If something is found to be wrong during this process, you
cannot go to the next SW/VR check or step.


4. DSP check
The following check will be made automatically.


4-1. Initialization test
When the result is 'NG', "ERROR 1" will appear on the LCD
screen and you will not be able to go to the next step.
If the result is 'OK', go to the next step without displaying
anything.


4-2. Internal RAM read/write test
When the result is 'NG', "ERROR 2" will appear on the LCD
screen and you will not be able to go to the next step.
If the result is 'OK', go to the next step without displaying
anything.


4-3. External RAM read/write test
When the result is 'NG', "ERROR 3" will appear on the LCD
screen and you will not be able to go to the next step.
If the result is 'OK', go to the next step without displaying
anything.

10. Residual noise check
"TEST 6" will appear on the LCD screen.
Switch the noise meter to 'JIS-A' or 'IHF' mode.
Check the output of OUTPUT L/R without connecting INPUT
and AUX IN (short circuited input, the state of short-circuited
signal and GND lines) using a noise meter.
OUTPUT L and R at or below -84.0 dBu (JIS-A) or at or below-
84.0 dBu (IHF)
