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 repair it. 4. Auto TRK gain : Adjust tracking 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 repair it. 5. Auto EQ : Adjust RF equalizer properly. Adjusted result is not reflected on the EEPROM. Execute this with CLVA turned on. 6. Auto L.F. Offset : Adjusts electrical offset in ARP. The adjusted value is applied to the EEPROM. During adjustment, lock the CLV. 7. Memorize Pullin : Sets the pull-in level to the EEPROM.

On this screen, eacf item can be automaticallyadjusted individually. Note, however, that there are some restriction. 0. Auto TRK Offset : Adjust tracking offset automatically. Adjusted result is reflected on the EEPROM. 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. 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 adjusted.
