On this screen, select the type of disc used.
“6. Disc type check” judges the disc loaded. Confirm that judg-
ment result meets the loaded disc type.
Judgment may fail if adjustment is not made yet immediately af-
ter EEPROM (IC801) Default Set. The CD which is not cut up to
the CD detection sensor position is judged as DVD. The optical
system will be damaged if other disc is loaded after selecting DVD
DL.
Be sure to set the disc type.
