Reading the Retry Cause Display
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.
Precedure:
1. Load a recordable disc whose contents can be erased into the unit.
2. For discs with no disc name, set the name display using the remote commander. (The time display is set after some time. Leave as it is if
desired.)
3. Press the
p
button immediately. Wait for about 10 seconds while pressing the button. (The AMS knob can be pressed instead of the YES
button for the same results.)
4. The fluorescent display tube displays “RTs@@c##e**”.
5. Press the
r
button to start recording. Then press the
^
button and start recording.
6. To check the “track mode”, press the
^
button to start play.
7. To exit the test mode, press the
1/u
button. 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
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
b2
The retry cause in this case is combined of “access fault”, “IVR rec error”, and “ader5”.
