3. Press to close the tray.
4. Press “CD DIRECT PLAY (5)” and wait until the tray is open.
5. Press and remove the CD.
6. Press to close the tray.
7. Press “n/STOP” to indicate Error Code.
· If several problem exist, error code will change each time when “n/STOP” is pressed. (e.g. F15 →F26 →F16 ....etc).
11.5. To clear all Error code
1. Press and hold button for 5 seconds.
2. FL indicator shows “CLEAR” for 1 second and change to “T”.
11.6. To exit from Self-Diagnostic function
1. Press button on main unit or remote control.
11.7. Power Amplifier Failure (F61)
1. When power amplifier fail, F61 will indicate automatically.
11.8. Description of Error Code
11.8.1. Abnormality detection for Deck Mechanism block
No. Abnormal Items Error Display Method of Detection
1MODE SW abnormal H01 Normal operation during mecha transition, MODE SW abnormal is
memorized. The content of abnormality can be confirmed in the
abnormal detection mode explained in the later section.
2REC INH SW abnormal H02 The content of abnormality can be confirmed in the abnormal detection
mode explained in the later section.
3HALF SW abnormal H03 The content of abnormality can be confirmed in the abnormal detection
mode explained in the later section.
4Reel pulse abnormal F01 The content of abnormality can be confirmed in the abnormal detection
mode explained in the later section.
11.8.2. Abnormality detection for CD/Changer block
No. Abnormal Items Error Display Method of Detection
1REST SW abnormal F15 Under normal operation (Self-Diagnostic Mode inclusive), this error
occurs when the REST SW ON is not detected within the specified time
and shall be memorized.
2 Transmission error between CD servo
LSI and micon
F26 Under normal operation (Self-Diagnostic Mode inclusive), this error occurs
when the selection is set to CD and SENSE=’H’ is detected and
SENSE=’L’ is not detected within a fail safe time (20ms) after system
command transmission was sent.
3CLAMP SW abnormal F16 Refer to section 11.8.4 (Mechanism Error Code Table) [M-0A] error is
detected.
4BOTTOM SW abnormal F17 Refer to section 11.8.4 (Mechanism Error Code Table) [M-09] error is
detected.
5POSITION SW abnormal F27 Refer to section 11.8.4 (Mechanism Error Code Table) [M-05 ~ M-08] error
is detected.
6SW1 abnormal F28 Refer to section 11.8.4 (Mechanism Error Code Table) [M-02 ~ M-08] error
is detected.
7SW2 abnormal F29 Refer to section 11.8.4 (Mechanism Error Code Table) [M-02 ~ M-08] error
is detected.
8OPEN SW abnormal H15 Refer to section 11.8.4 (Mechanism Error Code Table) [M-01] error is
detected.
9CLOSE SW abnormal H16 Refer to section 11.8.4 (Mechanism Error Code Table) [M-01] error is
detected.
10 DISC SENSOR F30 Refer to section 11.8.4 (Mechanism Error Code Table) [M-01] error is
detected.

11.8.3. Power supply related error detection
No. Abnormal Items Error Display Method of Detection
1POWER AMP output abnormal F61 During normal operation, if DCDET becomes ‘L’, normal POWER OFF
process shall not be executed, PCNT shall be switched to ‘L’
immediately. GOODBYE shall not be displayed and the error display F61
will be displayed instead.
2 seconds after the F61 display, ECONO shall be set to ‘L’ and FL
display shall be turned off.
The error content shall be memorized when the abnormality occurs and
can be displayed in the C-mecha self-diagnostic mode described later.
11.8.4. Error Code (CR20 Mechansim)
1. If mechanism problem occurs during normal or aging mode, the error code is “remembered” and shown on the FL display.
2. Reset Condition of Error Code
a. During cold start of micro-processor IC.
b. Restart of aging mode for the mechanism unit.
3. Mechanism Error Code
Mechansim Error Code Table
Error Code Description
M-00 No Error
M-01 OPEN Position - Horizontal Motion Abnormality at play position
M-02 PLAY Position - Horizontal Motion Abnormality at stock position
M-03 PLAY Position - Horizontal Motion Abnormality during changing
position
M-04 CHANGE Position - Horizontal Error of Stock position
M-05 CHANGE Position - Ascending motion Error
M-06 CHANGE Position - Descending motion Error
M-07 STOCK Position - Ascending motion Error
M-08 STOCK Position - Descending motion Error
M-09 Abnormality during change position (bottom switch)
M-0A Clamp Error
M-0B Access Failure - Access Time of more tha 30 secs (Total time
of automatic →Read TOC →Track access)
4. When the mechanism unit stops due to error during aging model, error code is remembered and counts of the errors are
displayed on the FL display.
