4-1. PRECAUTIONS FOR USE OF TEST MODE
(1) As loading related operations will be performed regardless of the test mode operations being performed, be sure to check that the disc is
stopped before setting and removing it.
Even if
§
button is pressed while the disc is rotating during continuous playback, continuous recording, etc., the disc will not stop
rotating.
Therefore, it will be ejected while rotating.
Be sure to press the EDIT/NO button to stop the disc rotation before pressing the
§
button.
(2) Detection of the rec-proof tab is not performed in the test mode. Therefore, the contents of the recorded contents will be erased when
operations in the mode for emitting the recording laser are performed (4-1-1) or when the
r
button is pressed. Consequently, be careful
not to set the continuous recording mode and traverse adjustment mode with a disc whose contents cannot be erased in the test mode.
