OK?..manual is complet and helpfull... for repairing such a old and rare boombox like JVC PCM it is necessary...
;
Super Anleitung. Ordentliche Auflösung. Das ganze noch in Deutsch wäre zu schön. Alle Datenblätter sind sauber Kopiert und alle Leitungswege sind sauber ausgeführt

Thanks God for the internet and thanks for the service like this - proffessional solution on time.

About the service it's very fast and reliable. About the manual the quality is high enough to read even the tiniest details on the wiring diagrams so you can't ask much more than that, let it alone for a manual of a product from 20 years ago. Thank you, very satisfied.

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.
