Sweet! I won the item on eBay and couldn't adjust the geometry or even keep a steady picure. This guide has the full schematics (not available anywhere else as far as I could tell), and was a bargain for the wealth of knowledge it contains. I hooked it up to my testing equipment, tweaked a few potentiometers and got it playing videogames in no time. Thanks!

It was just what I need to fix my old BMW's CD player. Very convenient also. Thank you.

Great Manual! It contains all the wiring schematics and mechanical exploded views that are essential for service and repair. I was surprised I even found this for such an old machine. Only wish I knew of this site many years ago.

If "Adjustment could not be executed." of "Fig. 2" is displayed, make readjustment. Even after the readjustment, if "Fig. 2" screen is still displayed, adjust the "MR duty" again and perform "drive frequency and the motor control adjustment" again. However, after all the above, if the adjustment is still impossible, the SWM unit, the fixed tube unit, GMR tape unit, or MR head unit may be defective.
