You will be asked if EEPROM data are initialized or not, and for
this prompt, select [0] and press the [ENTER] key. First, the servo
setting data in EEPROM, Emergency History and Hour Meter are
cleared to initialize. Then, [1] DVD-SL disc, [2] CD disc, and [3]
DVD-DL disc are adjusted in this order. Each time one disc was
adjusted, it is ejected, and therefore exchange the disc following
the message. You can exit the adjustment by pressing the x but-
ton. In adjusting each disc, the mirror time is measured to check
the disk type. In the auto adjustment, whether the disc type is cor-
rect is not checked unlike conventional models, and accordingly,
take care not to insert a different type of disc.
