mation & Service Information & DC offset Error Detection
Information Clear Mode, or DC offset Error Detection In-
formation Clear Mode.
• Also, do not display DEMO ON/OFF option items in the
MENU in STANDBY source in the above modes.
● Clearing backup / installer memory & CD mech-
anism information & service information & DC
offset error detection information
(Clearing E2PROM data)
1. While pressing and holding the [SRC] and [AUD] keys,
reset-start to start initializing the backup/installer memo-
ry data, CD mechanism information, service information
and DC offset 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 up-
dated).
[Service Information]
• Displays power ON time is displayed.
• Displays CD operation time.
• Displays number of CD EJECT times.
• 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
E2P_CLR: K
When fi nished but unsuccessful: Initialization NG
E2P_CLR: x
3. In this mode, even if the specifi ed time has passed, the
backup memory items are not written into E2PROM.
4. This mode is cancelled by resetting. (The last screen will
not be retained.)

TEST MODE
(Note) In this mode, the DC error detection display, "Pro-
tect" is not shown.
● Clearing DC offset error detection information
(Clearing E2PROM data)
1. Press and hold [ATT] and [AUD] 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 DC offset error
detection condition is displayed.
DC offset error detection display 1 (To show such detec-
tion as the improper connection, and other detection)
Upper
(Display) DC1_ OK__ (not detected)
row
DC offset error detection display 2 (To show the number
of capacitor leaks.)
(Display) DC2_ 0___ (not detected)
Middle
row
3. While the DC offset error detection condition is being
displayed as above, press and hold [1] key for 2 seconds
to clear the information about the improper connection,
and other detection. Press and hold [2] key for 2 seconds
to clear the information about the number of capacitor
leaks. (Clear E2PROM)
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 (Models for
destination "K" and "M")
FM: 50kHz↔200kHz, AM: 9kHz↔10kHz
• While power is OFF, press and hold [FNC] and [AUTO]
keys, and press [SRC] key to power ON.
ERR ( Improper connection or other error
is detected.)
1 (Leak is detected once.)
2 (Leak is detected twice.)
3 (Leak is detected 3 times.)
4 (Leak is detected 4 times or more.)
