RETRY CAUSE DISPLAY MODE

In this test mode, the causes for retry of the unit during recording can be displayed on the fluorescent indicator tube. During playback, the “track mode” for obtaining track information will be set.

This is useful for locating the faulty part of the unit.

The following will be displayed :

During recording and stop : Retry cause, number of retries, and number of retry errors.

During playback: Information such as type of disc played, part played, copyright.

These are displayed in hexadecimal.

Procedure 2: Press the LEVEL/DISPLAY/CHAR button while pressing the p button and MENU/NO button.

2.When the mode is set, “RTs 00c 00e 00” is displayed.

3.Press the rREC button to start recording. Then press the P button and start recording.

4. To check the “track mode”, press the · button to start play.

5.To exit the test mode, press the 1/u button, and turn OFF the power. When “TOC” disappears, disconnect the power plug from the outlet. If the test mode cannot be exited, refer to “Forced Reset” on page 8.

Reading the Display:

Convert the hexadecimal display into binary display. If more than two causes, they will be added.

Example

When 42 is displayed:

Higher bit : 4 = 0100 nb6

Lower bit : 2 = 0010 nb1

In this case, the retry cause is combined of “CLV unlock” and “ader5”.

When A2 is displayed:

Higher bit : A = 1010 nb7+b5

Lower bit : 2 = 0010 nb2

The retry cause in this case is combined of “access fault”, “IVR rec error”, and “ader5”.
