On this screen, manual adjustment can be made where jitter mea-
surement is executed.
0. Jitter : Turn on/off jitter measurement. Jitter will not
be measured unless the drive runs at CLV.
1. Focus Offset : Adjust focus offset.
2. Tilt Offset : Adjust tilt offset.
3. L.F. Offset : Adjust electrical offset in ARP.

On this screen, eacf item can be automaticallyadjusted individu-
ally.
Note, however, that there are some restriction.
0. Auto TRK Offset : Adjust tracking offset automatically. Ad-
justed result is reflected on the EEPROM.
Turn off tracking
on. Do not execute this at outside
because pickup moves outside. In the case
of CD, tracking simple AGC is also adjusted
here.
1. Auto Tilt Offset : Adjust tilt offset automatically. Adjusted
result is reflected on the EEPROM. Execute
this with CLVA turned on. If NG, retry this
after focus offset and tangential skew are
adjusted.
2. Auto Focus Offset: Adjust focus offset automatically. Adjusted
result is reflected on the EEPROM. Execute
this with CLVA turned on. If NG, retry this
after tilt offset and tangential skew are ad-
justed.

3. Auto Focus Gain : Adjust focus gain automatically. Adjusted
result is reflected on the EEPROM. Execute
this with CLVA turned on if possible. If
NG, the system will be defective, and re-
pair it.
4. Auto TRK gain : Adjust tracking gain automatically. Ad-
justed result is reflected on the EEPROM.
Execute this with CLVA turned on if pos-
sible. If NG, the system will be defective,
and repair it.
5. Auto EQ : Adjust RF equalizer properly. Adjusted re-
sult is not reflected on the EEPROM. Ex-
ecute this with CLVA turned on.
6. Auto L.F. Offset : Adjusts electrical offset in ARP. The ad-
justed value is applied to the EEPROM.
During adjustment, lock the CLV.
7. Memorize Pullin : Sets the pull-in level to the EEPROM.
