On this screen, turn on/off servo operation items necessary for
playing.
Normally, turn on the items from 0 sequentially, and normal trace
is executed at CLVA. In the tracking status, the sector address (or
time code (at CD)) is displayed.
If not displayed, the spindle is not locked, which means a failure.
In case of spindle system failure or no RF, the spindle system may
run, overriding the control.
In this case, do not press the CLVA.

0. LD

: Turn on/off the laser diode.

1. SP

: Turn on/off the spindle.

At SP ON, the spindle runs in constant velocity mode.

2. TILT : Turn on/off the tilt servo.
3. Focus : Focus searching is executed and focus is turned on.

Operation is terminated if focus is not turned on after
focus search is retried about 3 times.

4. Track : Turn on/off the tracking servo.
5. AGC : Turns on/off the focus error auto gain control by PULL

IN level.

6. Sled

: Turn on/off the sled servo.

7. CLVA : Spindle normal servo.
8. CAV : Spindle in constant velocity mode
9. Home : Return to home position.

In performing manual operation, observe the following points:
Select correct disc type on the Disc Type screen.
 First, select “0. Disc Type” and execute “7. Hydet init” and “8.
Sled init”.  (See Figure 12)
In case of abnormality, press [STOP] immediately to stop opera-
tion and turn off the power.
Do not execute Auto Adjust while executing FG Pause.
Also, as these commands are not protected, take care not to press
wrong key.
When PLL is locked, the sector address (or time code) is displayed
on the right side of SA.

On this screen, select the type of disc used.
“6. Disc type check” judges the disc loaded. Confirm that judg-
ment result meets the loaded disc type.
Judgment may fail if adjustment is not made yet immediately af-
ter EEPROM Default Set. The CD which is not cut up to the CD
detection sensor position is judged as DVD. The optical system
will be damaged if other disc is loaded after selecting DVD DL.
Be sure to set the disc type.

On this screen, track jump, etc. are executed.
Confirm the sector information (SI) to check the DVD_DL layer
jump direction. Even SI means layer 0, or odd SI means layer 1.
When 1TJ or 32TJ is executed, the tracking is turned on, but the
sled becomes just like initialization.
Also, after executing each jump except 1TJ (and FJ1, 2), the CLVA
mode is set.
The optical system will be damaged if make a jump in wrong di-
rection FJ0, FJ1, LJ0 and LJ1.

0. FWD 32TJ

: Jump 32 track forward (N track jump).

Adjusting range is (A1 – AF) with
A1 – A7: +25 to +175 mV,
A8 – AF: 0 to –175mV.

2. TRK. Gain 2 (CD)

Adjusting range is (88 – C8) with lower
4 bits fixed.

TRK. Off set: In the tracking offset adjustment for DVD, based

on the peak and bottom data measured by DSP, the
SSL33P3720A cansels the offset roughly, then the
DSP adjusts it finely.
Here, finely adjusted value is set. As adjustment is
made by DSP only.
DC component of tracking traverse does not
change.
For the CD, only this set value changes.

TRK. Gain : In the tracking gain adjustment for CD, based on

the peak and bottom data measured by DSP, the
CXA2556 on the sets simple AGC to 5 steps of
–3.2, –1.6, 0, +1.6, +3.2 dB (Auto Tracking Off-
set), then the DSP makes setting (Auto Tracking
Gain). Here, DSP setting can be made. In the case
of DVD, only DSP setting is executed.
