Procedure for Using the Self-Diagnosis Function (Error History Display Mode)
Note: Perform the self-diagnosis function in the “error history display mode” in the test mode. The following describes the least required steps. Be careful
      not to enter other modes by mistake. If other modes are set accidentally, press the ^ (CD) button to exit that mode.
1.   With the power off, press the =0 button while pressing the [VOLUME–] button.
2.   Press the [VOLUME+/–] button to display “ERR DP MODE”.
3.   Pressing the p (CD) button sets the error history mode and displays “total rec”.
4.   Select the contents to be displayed or executed with pressing the [VOLUME+/–] button.
5.   Pressing the 6 (CD) button displays or executes the contents selected.
6.   Pressing the 6 (CD) button another time returns to step 4.
7.   Pressing the ^ (CD) button displays “ERR DP MODE” and exits the error history mode.
8.   To exit the test mode, press the p (MD) button while pressing the [FUNCTION] button.
     The unit sets into the STANDBY state, and the test mode ends.
                                                                         –3–

5-8.      AGING MODE
This unit is provided with an aging mode.
In this mode, MD and CD operations are performed alternately according to the following sequence.
Aging will be carried out continuously unless an error occurs.
If an error occurs, the status and number of cycles are displayed alternately, and operations stop. (Refer to Table 1.)

Procedure:
1. Load a recordable disc (MD) and CD test disc (YEDS-18). (*Note 1)
2. While pressing the [VOLUME–] button, press the )+ button.
3. Aging is executed in the above sequence.
4. To end, press the p (CD or MD) button.
*Note 1: Any CD can be used, but one with a short last track is recommended. The time of one aging cycle will be longer if the last track is long.
         Also use a CD in which the length of the last track x 20 does not exceed the recording time of the recording MD.
                                                                      – 25 –
