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 the  

§(MD)  key 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.
Always press the  EDIT/NO  key first before pressing the
§(MD)  key.

2. The erasing-protection tab is not detected in the test mode. There-

fore, when modes which output the recording laser power such
as continuous recording mode and traverse adjustment mode,
etc. are set, the recorded contents will be erased regardless of
the position of the tab. When using a disc that is not to be erased
in the test mode, be careful not to enter the continuous record-
ing mode and traverse adjustment mode.
