• When in the test mode, serial number is not written with a
serial-number-writing jig.
• When in the test mode, when DC offset error detection
is run, the detection information is not written into the
E2PROM.
• When in the test mode, even if the specified time has
passed, back-up memory items are not written into
E2PROM.
• DEMO mode shall not be operated while in the test mode,
CD Mechanism Information & Service Information & DC
Offset Error Detection Information Clear Mode, or DC
Offset Error Detection Information Clear Mode.
• Also, do not display DEMO ON/OFF option items in the
MENU in STANDBY source in the above modes.
● Clearing CD mechanism information & service
information & DC offset error detection informa-
tion (Clearing E2PROM data)
1. While pressing and holding the [MENU] and [ATT]
keys, reset-start to start initializing the CD mechanism
information, service information and DC error detection
information.
(While "– – – –" is being displayed, power can be ON for
30 minutes.)
[CD mechanism information]
• Displays I2C communication condition
• Displays CD mechanism error log
• Displays CD loading error data.
• Displays CD ejection error data.
• Displays CD time code error count data (missing count).
• Displays CD time code error count data (count not
updated).
[Service Information]
• Displays power ON time is displayed.
• Displays CD operation time.
• Displays number of CD EJECT times.
• Displays number of times panel was opened/closed.
• Displays forced Power OFF data.
[DC offset error detection information]
• DC offset error detection display 1
• DC offset error detection display 2
2. After the initialization process is completed, the following
is displayed.
When successfully completed: "CD_O_ _ _"
When fi nished but unsuccessful: "CD_X_ _ _"
3. This mode is cancelled by resetting. (The last screen will
not be retained.)
(Note) In this mode, the DC offset error detection display,
"PROTECT" is not shown.

TEST MODE
● Clearing DC offset error detection information
(E2PROM data clearing)
1. Press and hold [3] and [6] keys and reset-start to go into
the DC offset error display mode.
(While "– – – –" is being displayed, power can be ON for
30 minutes.)
2. While in STANDBY source, the current overall DC offset
error detection condition is displayed.
When not detected: "DC_ _OK_ _" : None of capacitor
leak, improper connection, etc. has been detected.
When detected: "DC_ _ERR_" : Any one of capacitor leak,
improper connection, etc. has been detected.
3. Use the following procedure to check the details of DC
offset error detection information.
[1]
Key pressed briefl y: DC offset error detection display 1 (To
key
show such detection as the improper connection and other
detection)
Key pressed and held for 2 seconds: Clear the information
that indicated if there was such an error as improper
connection and other error.
(Display) DC1_ OK_ _ (No error was detected)
[2]
Key pressed briefl y: DC offset error detection display 2 (To
key
show the number of capacitor leaks.)
Key pressed and held for 2 seconds: Clear the information
that indicates the detected number of capacitor leaks.
(Display) DC2_ 0_ _ _ (No error was detected )
4. DC offset error display mode is cancelled by resetting. (The
last screen will not be retained.)
(Note) In this mode, the DC offset error detection display
"PROTECT" is not shown.
● FM/AM channel space switching (KDC-MP4036U/
MP435U/X491 only)
While power is OFF, press and hold [1] and [5] keys, and
press [SRC] key to power ON.
● Security
How to enter the forced POWER ON mode
•
While "_ _ _ _" is being displayed, while simultaneously
pressing [MENU] key and [4] key, press [RESET] button,
With this, it is possible to turn the power on for 30 minutes
only.
ERR_ (Improper connection or other error is
detected.)
1
(Leak was detected once.)
2
(Leak was detected 2 times.)
3
(Leak was detected 3 times.)
4
(Leak was detected 4 times or more.)
