26、, be sure to check that the disc is stopped before setting and remov- ing it. Even if the EJECT switch is slid while the disc is rotating during continuous playback, etc., the disc will not stop rotating. Therefore, it will be ejected while rotating. Be sure to slide the EJECT switch after pressing

27、the STOP button and the rotation of disc is stopped. 2.The erasing-protection tab is not detected in the SERVICE MODE. Therefore, when operating in the recording laser emission mode and pressing the REC button, the recorded contents will be erased regardless of the position of the tab. When using a

28、disc that is not to be erased in the SER- VICE MODE, be careful not to ENTER the continuous re- cording mode and traverse adjustment mode. 2-1-1.
