●How to enter the test mode
Press and hold the [1] and [3] keys and reset.
(While “– – – –” is being displayed, power can be ON for 30
minutes.)
●How to clear the test mode
Reset, momentary power down, Acc OFF, Power OFF, detach
the panel.
●Test mode default condition
• Source is STANDBY.

●Clearing CD mechanism information and service
information (E2PROM data clearing)
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 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
2. After the initialization process is completed, the following is
displayed.
When successfully completed : “CD_O_ _ _”
When finished but unsuccessful:“CD_X_ _ _”
∗CD mechanism information clearing is no good.
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_”.
Once this product detected a DC offset error, even if it is re-
started (or reset), its display displays “DC_ERR_”.
However, if the error is detected while in Test Mode, it is not
saved in E2PROM.
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 DC offset error con-
dition is displayed.
When detected : “DC_ERR_ _”
When not detected: “DC_OK_ _ _”
3. While error condition is being displayed, press [AUTO] key
to clear the detection data. (Clear E2PROM)
4. DC offset error display mode is cancelled by resetting.(The
last screen will not be retained.)

ond or longer to enter the security registration mode.
3. Input the security code, using [FM] / [AM] / [ ] / [ ] keys.
[FM] key: number up / [AM] key: number down
[ ] key:cursor to right / [ ] key:cursor to left
4. After inputting the code, press [ ] key for 3 seconds or
longer which causes “RE-ENTER” to be displayed.This is
for “confirming” the code. Use the method in the step 3 to
re-enter the code.
5. Then, press [ ] key for 3 seconds or longer, which will
display“APPROVED”.This completes the security code reg-
istration.
6. Release the test mode. (Refer to “How to clear the test
mode”.)
∗All clear cannot be used to clear the security code.
3) How to clear the programmable security code
(KDC-MP532U only)
1. While “– – – –” is being displayed, press [ ] key for 3
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.
