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 EJECT 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.
Always press the EDIT/NO button first before pressing the EJECT button.

2 The erasing-protection tab is not detected in the test mode. Therefore, when modes which output the recording laser power such as continu-

ous 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 recording mode and traverse adjustment
mode.

3 Most buttons can not be used while the error rate is displayed due to bugs of IC121 CXD2535CR.

Each time the DISPLAY button is pressed, the display changes in the following order.
