Security
• How to enter the forced POWER ON mode
While "– – – –" is being displayed, while simultaneously
pressing [Q] key and [4] key, press [RESET] button, With
this, it is possible to turn the power on for 30 minutes only.
• How to clear the programmable security code
∗ Operation 1
1. While "– – – –" is being displayed, press [
seconds or longer while pressing the [AUTO] key. This
makes the "– – – –" display disappear.
2. Input "KCAR", using the remote controller.
Press [5] key of the remote controller twice (Input for "K")
and press [ ] key.
Press [2] key of the remote controller 3 times (Input for
"C") and press [ ] key.
Press [2] key of the remote controller once (Input for "A")
and press [ ] key.
Press [7] key of the remote controller twice (Input for "R")
and press [ ] key.

∗ Operation 2
1. After code has been registered, in STANDBY source,
press and hold the [Q] key for 1 second or longer to go
into the MENU. While "CODE_CLR" is displayed, press
the [ ] keys for 1 second or longer to cancel the secu-
rity code.
2. Input pre-registered code, using [FM] / [AM] / [
keys.
[FM] key: numbers go up / [AM] key: numbers go down
[ ] key: cursor moved to the right / [
moved to the left
3. Press the [ ] key for 3 seconds or longer and "CLEAR"
is displayed.
4. When the input code is not registered, "ERROR" is dis-

Clearing CD mechanism information and service
information (Clearing E2PROM data)
1. While pressing the [Q] key and [ATT] key, reset-start to start
CD mechanism and service information initialization.
(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 number of times PANEL was opened / closed.
• Displays forced Power OFF data.
2. After the initialization process is completed, the following is
displayed.
When successfully completed: "CD_O___".
When finished but unsuccessful: "CD_X___"
3. This mode is cancelled by resetting. (The last screen will
not be retained.)
Clearing DC offset error detection data (E2PROM
data clearing)
If DC voltage difference (DC offset error) is detected between
audio power amplifier (power IC) ± outputs, "DC_ERR_" is dis-
played on the display. When this occurs, the audio is forced-
mute and the display displays only "DC_ERR_".
