In using the manual operation menu, take care of the following
points. These commands do not provide protection, thus requiring
correct operation. The sector address or time code field is dis-
played when a disc is loaded.

1. Set correctly the disc type to be used on the Disc Type

screen.
The disc type must be set after a disc was loaded.
The set disc type is cleared when the tray is opened.

2. After power ON, if the Drive Manual Operation was se-

lected, first perform “Reset SLED TILT” by opening 1.
Disc Type screen.

3. In case of an alarm, immediately press the 

[STOP]

 but-

ton to stop the servo operation, and turn the power OFF.

On this screen, the mirror time is measured to judge the disc and it
is written to the EEPROM. First load DVD SL disc and press 

[1]

,

next load CD disc and press 

[2]

, and finally load DVD DL disc

and press 

[3]

.

The adjustment must be executed more than once after default
data were written. External vibration or shock to the player must
not be given. Reference value for DVD is from 10 to 20, and for
CD, from 28 to 4F.
Check that the value of CD is larger than that of DVD.
When those values are beyond a range perform this adjustment
again.
From this screen, you can go to another mode by pressing

Also, opening the tray causes the set disc type to be cleared. In
this case, set the disc type again after loading.
In performing manual operation, the disc type must be set.
Once the disc type has been selected, the sector address or time

On this screen, the servo on/off control necessary for replay is
executed. Normally, turn on each servo from 1 sequentially and
when CLVA is turned on, the usual trace mode becomes active. In
the trace mode, DVD sector address or CD time code is displayed.
This is not displayed where the spindle is not locked.
The spindle could run overriding the control if the spindle system
is faulty or RF is not present. In such a case, do not operate CLVA.

_            CLEAR: Default Set

This screen displays current servo adjusted data stored in the
EEPROM. Though adjusted data can be initialized with the

[CLEAR]

 key, they cannot be restored after initialization.

So, before clearing, make a note of the adjusted data.
For reference, the drive has been designed so that the gain center
value is 20 and offset value is 80. Other values will be in a range
of 10 to 80. If extreme value such as 00 or FF is set, adjustment
will be faulty. In such a case, check for disc scratch or cable dis-
connection, then perform adjustment again.

On this test mode screen, selecting
