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 NEXT
or PREV key, but you cannot enter this mode from another mode.
You can enter this mode from the Operation Menu screen only.

number of the loaded disc. The selected disc type is displayed at the
bottom. Selecting 1 automatically selects and displays the disc
type. In case of wrong display, retry "Disc Check Memory".

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
code display field will appear as shown below. These values are

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.

Reset the Sled and Tilt to initial position.
Judge automatically the loaded disc. As
the judged result is displayed at the
bottom of screen, make sure that it is
correct.
If Disc Check Memory menu has not
been executed after EEPROM default
setting, the disc type cannot be judged.
In this case, return to the initial menu
and make a check for three types of
discs (SL, DL, CD).
Select the loaded disc. The adjusted
value is written to the address of
selected disc. No further entry is
necessary if 1 was selected.
