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 (IC806).

On this screen, each 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
(IC801). Turn off tracking with the Focus
turned on. Do not execute this at outside
track 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 (IC801).
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 (IC801).
Execute this with CLVA turned on. If NG,
retry this after tilt offset and tangential skew
are adjusted.

3. Auto Focus Gain : Adjust focus gain automatically. Adjusted
result is reflected on the EEPROM (IC801).
Execute this with CLVA turned on if pos-
sible. If NG, the system will be defective,
and repair it.
4. Auto TRK gain : Adjust tracking gain automatically. Ad-
justed result is reflected on the EEPROM
(IC801). Execute this with CLVA turned on
if possible. If NG, the system will be de-
fective, and repair it.
5. Auto EQ : Adjust RF equalizer properly. Adjusted re-
sult is not reflected on the EEPROM
(IC801). Execute this with CLVA turned on.
6. Auto L.F. Offset : Adjusts electrical offset in ARP (IC806).
The adjusted value is applied to the
EEPROM (IC801). During adjustment, lock
the CLV.
7. Memorize Pullin : Sets the pull-in level to the EEPROM
(IC801).

On this screen, various checking can be made. Note, however, that
some items such as EEPROM (IC801) Default set are not recover-
able.
1. EEPROM Default set : Use this to set EEPROM (IC801) set
values to default values. Before execut-
ing this, it is recommended to record
current values.
6. EEPROM data : Display EEPROM (IC801) set values
list.
