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 procedure. Be
careful not to enter other modes by mistake. If you set other modes accidentally, press the  MENU/NO  button to release the mode.
1. While pressing the 
[       AMS       ]
 knob and
x
button simultaneously, connect the power plug to the outlet, and release the
[       AMS       ]
 knob and
x
button simultaneously to display “[Check]”.
2. Turn the 
[       AMS       ]
 knob and when “[Service]” is displayed, press the 
[YES]
 button to display “AUTO CHECK” (C01).
3. Turn the 
[       AMS       ]
 knob to display “Err Display” (C02).
4. Press the 
[YES]
 button to sets the error history mode and displays “op rec tm”.
5. Select the contents to be displayed or executed using the 
[       AMS       ]
 knob.
6. Press the 
[       AMS       ]
 knob to display or execute the contents selected.
7. Press the 
[       AMS       ]
 knob another time returns to step 4.
8. Press the 
[MENU/NO]
 button to display “Err Display” (C02) and release the error history mode.
9. To release the test mode, press the
I/1
button. The unit sets into the STANDBY state, and the test mode ends.
SELF-DIAGNOSIS FUNCTION
The deck’s self-diagnosis function 
automatically checks the condition of the MD 
deck when an error occurs, then issues a three- 
or five-digit code and an error message on the 
display. If the code and message alternate, find 
them in the following table and perform the 
indicated countermeasure. Should the problem 
persist, consult your nearest Sony dealer.
C11/Protected
, Take out the MD and close the record-protect 
slot.
C12/Cannot Copy
• You tried to record a CD with a format that the 
external device connected to the deck does not 
support, such as CD-ROM or video CD.
, Remove the disc and insert a music CD.
C13/REC Error
, Set the deck in a stable surface, and repeat the 
recording procedure.
• The inserted MD is dirty (with smudges, 
fingerprints, etc.), scratched, or substandard in 
quality.
, Replace the disc and repeat the recording 
procedure.
C13/Read Error
, Take out the MD and insert it again.
C14/TOC Error
, Insert another disc.
, If possible, erase all the tracks on the MD. 
C41/Cannot Copy
• The sound source is a copy of commercially 
available music software, or you tried to record a 
CD-R (Recordable CD).
, The Serial Copy Management System 
prevents making a digital copy. You cannot
record a CD-R.
C71/Din Unlock
• The sporadic appearance of this message is 
caused by the digital signal being recorded. This 
will not affect the recording.
• While recording from a digital component 
connected through the DIGITAL IN connector, 
the digital connecting cable was unplugged or the 
digital component turned off.
, Connect the cable or turn the digital 
component back on.
