4-4. SACD (DL) DISC OPERATION CHECK
(• Perform as necessary)
This checking performs the focus jump using a DL disc, which is
a dual-layer HD disc, to verify the stability of the set.
A set of layer 0 most-outside track access (only once)
t
one-second
trace
t
focus jump (layer 0
t

t
one-second trace
t
focus jump
(layer 1
t

Checking Method:
1. After setting the test mode, rotate the
[ AMS ]
dial to
select “91 FJUMP CHECK” and press the
[ AMS ]
dial
to enter.
2. The tray will open automatically, and then set the DL disc.
3. With “DISC IN&JOG ON” displayed, press the
[ AMS ]
dial.
4. The tray will be loaded in automatically, and then the test will
start.
5. During the test, “NOW TEST
iiii
” is displayed.
6. Upon successful completion of the check, “OK!” will be
displayed and the tray will open automatically. (In case of
NG, “NG! ERR FJ-UP” or “NG! ERR FJ-DWN” is displayed)
7. Take the DL disc out and press the
[OPEN/CLOSE ]
button,
and the test mode selection display will be back
4-5. SHIPPING 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 SETUP MODE” (AEP model) or “8F SETUP U/
CA” (US and Canadian models) and press the
[ AMS ]
dial to enter.
2. “INITIAL OK” is displayed and the test mode selection display
will be back immediately.
3. Press the
[POWER]
button to turn the power off.
The following setups are established in the shipping mode
1. Initialization of EEPROM (IC903)

• Resetting the cumulative light emission time of the laser
Note
: Even if the shipment mode setting mentioned above is made, the
disc check threshold value attained in the 3. SET CHECK is not
cleared.
2. The optical pick-up moves to the home position (most-inside
track)

4-6. WAVEFORMS CHECK
BU Electrical Adjustment Mode
The BU electrical adjustment mode is used to check the S curve
waveform, traverse waveform, RF waveform, and CLV jitter. After
a disc is placed on the tray, each time the
[ AMS ]
dial is
pressed, the check mode is switched in order for S curve
waveform
t
traverse waveform
t
RF waveform
t
CLV jitter (for
the CD).
S Curve Check
Connection:
Checking Method:
1. After setting the test mode, rotate the
[ AMS ]
dial to
select “9C. BU DENCHO” and press the
[OPEN/CLOSE ]
button. Place the test disc (PATD-012 or YEDS-18 or SATD-
S5 or SATD-S4) on the tray and close the tray, then press
the
[ AMS ]
dial.
2. At the completion of disc type check, “CD DETECT” will be
displayed (for PATD-012 or YEDS-18).
Note:
For the SATD-S5 or SATD-S4, “SL DETECT” is displayed.
3. Press again the
[ AMS ]
dial, and the S curve waveform
check mode will become active and “S-CURVE MODE” will
be displayed.
4. Connect an oscilloscope to the TP506 (FE) and TP504 (AVC)
on the MAIN board.
5. Check that the level
A
and
B
of waveform on the oscilloscope
satisfy the specification.
Specified Value:
Disc
A
B
SATD-S5 or
SATD-S4
PATD-012 or
0.7 to 1.7 Vp-p
–0.1 to +0.1V
YEDS-18
Note:
For easier observation of this waveform, extend the sweep time
and raise the brightness.
Checking and Connecting Location : See page 25.
