The stability of the set can be checked by repeating the combined
operation of focus jump (layer 0t1, layer 1t0) and access to
the most inward trackymost outward track by the set number of
times or until an error occurs using the dual layer HD disc, DL
disc.

start. (It takes about ten and several seconds to set up the disc
as two layers of layer 0 and layer 1 are adjusted)

6. At the completion of setup, “F.JUMP TIMES” will be dis-

played.

7. Rotate the

If the panel door cannot be opened, the time-out error is triggered
and the measurement is also stopped at this stage. Note that the
tray can push the door forcibly as the software judges the door as
it is in the OPEN state, if the door open/close detector switches
(S1022 and S1023 on the DOOR SW board) have abnormality.

Measurement of table rotation hours, tray open/close hours and
panel door open close hours can be executed together with CDM59.

Procedure
1. Enter the TEST mode. Turn the 

[         AMS        ]

 dial and select

59 Table Init. Press 

[        AMS        ]

 once (that enables the

[OPEN/CLOSE]

 key.)

2. When the message INITIAL OK appears, press the 

[OPEN/

CLOSE]

 key to eject the tray. Place a disc in the DISC1 of the

table. (Be sure to place a disc in DISC1. If a disc is placed in
any locations other than DISC1, the correct measurement can-
not be executed. Therefore, be sure to place a disc in DISC by
using the 

[DISC SKIP]

 key.)

3. Select 58 CDM Check by turning 

[        AMS        ]

 and press

[        AMS        ]

 once.

4. Measurement starts automatically.
5. When the measurement is completed, the message DOOR OP

ss.s (s is a decimal number) appears on the FL display.

6. Result of measurement can be check by turning 

[        AMS        ]

.

If any measurement item does not meet specification, a mes-
sage “ng” is displayed next to the measurement value.

7. When you want to repeat the test, press 

[        AMS        ]

 again.

8. Press the 

[OPEN/CLOSE]

 key to terminate the test and re-

move the disc.
* 1.The measurement can be performed without placing a disc.

However, the BU chucking time and unchucking time will
be slightly different from the actual values.

* 2.When the machine enters this mode once, it cannot return

to the normal test mode. If any other tests are desired, turn
off the main power once and then back on again to enter
the test mode.

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

[        AMS        ]

 dial to

select “94. SET AGING” and press the 

[        AMS        ]

 dial

to enter.

2. When “AGING TIMES” is displayed, rotate the 

[        AMS        ]

dial to set the number of aging times. (For the number of times,
every 10 times can be set. Setting 0 (zero) eliminates the count
limitation where the aging is repeated until an error occurs)

 Do not perform unmanned overnight aging..

3. Press the 

[        AMS        ]

 dial, and “AGING START” will be

displayed instantaneously, then “DISC IN & JOG ON” will be
displayed and the tray will come out automatically.

4. Place a disc (CD or the SACD SL disc) on the tray. In the case

of SCD-C555ES, the multiple discs can be placed. Even when
the discs (CD or the SACD SL disc) of different types are
mixed, the aging test can be performed. Use the 

[DISC SKIP]

key when placing a disc. When discs are placed in positions,
turn the 

[        AMS        ]

 dial.

5. The aging test starts.
6. At the completion of aging by the set number of times, the

tray will come out automatically and the check will stop.
Typical time required for aging    About 1 hour/100 times
“AGING SUCCESS!” will be displayed if no error occurred
in the aging, or the error will be displayed if an error occurred.
(Refer to the following error list)

1. Start up the unit in the normal operation mode.
2. While press the 

[STOP]

 key, turn the 

[         AMS         ]

 dial and

then press the 

[CONTINUE]

 key. (The program does not ad-

vance if these keys are not pressed in the above sequence.)

3. The panel door repeats opening and closing.
4. The messages “AP-B 000000” (during open) t  “AP-C

000000” (during close) are repeated on the FL display. Num-
ber of times of open/close are displayed in decimal number in
“000000” with OPEN/CLOSE as a set.

5. Press the 

[STOP]

 key to terminate the aging mode and to re-

turn to the normal mode.

The repaired set must be initialized, and for this purpose the set
should be set to the shipping mode.

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

[        AMS        ]

 dial to

select “8d Set Up Init” and press the 

[        AMS        ]

 dial to

enter.

2. “8D 000000000 00” will be displayed, and if the scroll starts

in the left direction, the set initialization has completed

3. Press the 

[POWER]

 button to turn the power off.

Take care not to leave the test disc in the set.

An error occurring during the check in the aging mode of the test mode is displayed automatically (scroll display) immediately when the
error occurred.

< How to view the error history >
1. Select “95 DISP ERROR” with the 

[        AMS        ]

 key, and press the 

[        AMS        ]

 key once.

2. The error that has occurred lastly in the set and the signal status (H = 1, L = 0) at that time are displayed on the FL display by scrolling.

(Types of the errors and the signal status that can be checked, are the same as the error display of the aging mode.)

3. Press the 

[        AMS        ]

 key once again to show the error history repeatedly.

4. When the error history is displayed with scrolling once, the mode returns to the normal test mode.
