0. Auto Tilt Gain : Adjust tilt gain. Adjusted result is not re-
flected on the ROM. Executed this at least
with LD and Tilt turned on. (Not used at
present)
1. Auto TRK Offset : Adjust tracking offset automatically. Ad-
justed result is reflected on the ROM. Turn
off tracking with the Focus turned on. Do
not execute this at outside track because
pickup moves outside. It is recommended to
turn on CLVS.
2. Auto Tilt Offset : Adjust tilt offset automatically. Adjusted re-
sult is reflected on the ROM. Execute this
with CLVA turned on. If NG, retry this after
focus offset and tangential skew are adjusted.
3. Auto Focus Offset : Adjust focus offset automatically. Adjusted
result is reflected on the ROM. Execute this
with CLVA turned on. If NG, retry this after
tilt offset and tangential skew are adjusted.
4. Auto EQ : Adjust RF equalizer properly. Adjusted re-
sult is not reflected on the ROM. Execute
this with CLVA turned on.
5. Auto Focus Gain : Adjust focus gain automatically. Adjusted
result is reflected on the ROM. Execute this
with CLVA turned on if possible. If NG, the
system will be defective, and repair it.
6. Auto TRK gain : Adjust tracking gain automatically. Adjusted
result is reflected on the ROM. Execute this
with CLVA turned on if possible. If NG, the
system will be defective, and repair it.
7. Auto VCO : Adjust VCO voltage. Adjusted result is re-
flected on the ROM. Execute this with all
items turned OFF.

On this screen, various checking can be made. Note, however, that
some items such as EEPROM Default set are not recoverable.
0. SRAM check : Check communication between H8 and
SRAM (CXK58257).
1. EEPROM check : Check communication between H8 and
EEPROM (AK6420).
2. CDDET check : Check CD detection sensor. Result is
shown on the right side.
3. EEPROM Default set : Use this to set EEPROM set values to
default values. Before executing this, it
is recommended to record current values.
4. Hydet init : Initialize for direct searching.
5. Sled init : Cancel the sled stop position offset.
6. EEPROM data : Display EEPROM set values list.
Display is made with HEX numbers
“00”~”FF”.
If the check on this screen is NG EMG turns to the number that is
not “00..”
