The communication between microcomputer and main ICs (self-
diagnosis) and the fluorescent display tube all lit are checked.

Checking Method:
1. After setting the test mode, rotate the 

[        AMS        ]

 dial to

select “92. SET CHECK” and press the 

[        AMS        ]

 dial

to enter.

2. When  “SET TEST  START” is displayed, rotate the

[        AMS        ]

 dial clockwise by 1 click to select “0. IC&FL

CHECK?” and press the 

[        AMS        ]

 dial to enter.

3. A checking will start automatically, and “0. IC&FL CHECK”

will be displayed. (Checking time is about 3 seconds)

4. After IC communication check, all segments of fluorescent

display tube will be lit. At this time, check visually for a skipped
character.

5. At successful completion of check, “0. IC CHECK OK” is

displayed. In this case, no error exists in the IC interface. Pro-
ceed to 4-2. AUTO CHECK.

The check mentioned above tests the communication from micro-
computer to main ICs. Even if the check successfully finished, the
IC to be checked is not always normal. Consider it for reference
only.

6. In case of an IC communication error, the following display

will be given during the checking. Possible causes of error are
as listed below.

Causes Common to Each IC:
1. Faulty communication line between microcomputer and each

IC.
Disconnected patterns, floating series resistors, bridge, etc.

2. Faulty IC supply voltage.

Particularly, check D+3.3V voltage. (D+5V for display mi-
crocomputer)

3. Faulty microcomputer communication port to each IC

In case of more than two errors, the error display is switched over
one after another, thus making the reading difficult.
In such a case, press again the 

[        AMS        ]

 dial to make a

recheck for error reading.

The auto check is performed to check if the set operates stably. Though a checking is made automatically, whether the measured data are
within the specification is evaluated by the service person. The auto check results in NG immediately, if the check itself causes an error.

Setting Method of Auto Check Mode:
1. After setting the test mode, rotate the 

[        AMS        ]

 dial to select “92. SET CHECK” and press the 

[        AMS        ]

 dial to enter.

2. When “SET TEST START” is displayed, rotate the 

[        AMS        ]

 dial clockwise by 2 clicks to select “1. TOTAL CHECK?”

and press the 

[        AMS        ]

 dial to enter.

3. When “10. TOTAL CHECK” is displayed, rotate the 

[        AMS        ]

 dial clockwise by 1 click to select “11. AUTO  CHECK?”.

Checking method:
1. Press the 

[    OPEN/CLOSE]

 button to open the tray and place the test disc *1.  The 

[    OPEN/CLOSE]

 key is disabled immediately

after setting the test mode. Be sure to initialize the table.

2. Press the 

[        AMS        ]

 dial, and the following check will be performed automatically.

3. Finally, the test disc will be ejected and the auto check will finish.
4. “AUTO CHECK OK” will be displayed at successful completion of auto check.
5. Recheck is enabled if the 

[        AMS        ]

 dial is pressed in step 4. (Also, use this operation when exchanging the test disc)

6. In case of an error during the checking, the check is interrupted automatically and the error is displayed. (Error display example:

“DISC DETECT ERROR”)  After error display, “CONT?STOP (J/S)” is displayed. In this case, if the 

[        AMS        ]

 dial is pressed,

the check where the error occurred is skipped and you can proceed to the next check. Also, 

x

if button is pressed, the check finishes

and “AUTO CHECK NG” is displayed when even one NG item exists.

*1 Use PATD-012 or YEDS-18 for CD, and SATD-S5 or SATD-S4 for SACD (SL). Using another disc will result in a checking failure.

 dial clockwise by 1 click, and the “LOAD IN” will be displayed.

5. Press the 

[        AMS        ]

 dial to enter. The LOAD IN TIME measured value will be displayed.

6. Compare the displayed value with the following specified value.
7. Hence, repeat step 4 to 6 (display is variable) and read the measured data respectively.
8. Compare the measured data with the specified value to check for NG item.

Blank display of measured value means that an error occurred during the checking or no measurement was taken place.

Specified Value:
(1) SACD (Use the test disc SATD-S5 or SATD-S4)
