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:
1. Load a recordable disc whose contents can be erased into the unit.
2. Press the [MENU/NO] button. When “Edit Menu” is displayed on the fluorescent indicator tube, turn the [AMS] knob to
display “All Erase?”.
3. Press the [YES] button. (Or press the [AMS] knob)
4. When “All Erase??” is displayed on the fluorescent indicator tube, the music calendar number blinks.
5. Press the [YES]button to display “Complete!!”, and press the p button immediately. Wait for about 15 seconds while pressing the
button. (The [AMS] knob can be pressed instead of the [YES]button for the same results)
6. When the “TOC” displayed on the fluorescent display tube goes off, release the p button.
7. Press the [REC] button to start recording. Then press the P button and start recording.
8. To check the “track mode”, press the · button to start play.
9. To release the test mode, press the 1/u button, and turn OFF the power. When “TOC” disappears, disconnect the power plug from the
outlet.

Occurring conditions
When track jump (shock) is detected
When ADER was counted more than five times
continuously
When ADIP address is not continuous
When DIN unlock is detected
When not in focus
When ABCD signal level exceeds the specified range
When CLV is unlocked
When access operation is not performed normally
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 n b6
Lower bit : 2 = 0010 n b1
In this case, the retry cause is combined of “CLV unlock” and “ader5”.
When A2 is displayed:
Higher bit: A = 1010 n b7+b5
Lower bit : 2 = 0010 n b1
The retry cause in this case is combined of “access fault”, “IVR rec error”, and “ader5”.
