3. While in this mode, even after an elapse of a pre-set time,
no backup memory items will be written to the E2PROM.
4. This mode is released by resetting. (What was on 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] or
[TI] 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.)

FM/AM channel space switching
(KDC-MP632U/X590/X7533U)
From the Power OFF condition, while pressing [1] and [5] keys
down simultaneously, press the [SRC] key and turn power ON.
While “– – – –” is being displayed, by resetting while pressing
[Q] key and [4] key simultaneously, it is possible to turn the
• How to register the security code on the “Car Au-
dio Passport” after replacement of the E2PROM
(IC10) (KDC-W6534U/W6534UY/X7533U)
1. Enter the test mode. (Refer to the section on “How to Enter
the Test Mode.”)
TEST MODE
2. Enter the MENU by pressing [Q] key for less than 1 sec-
ond.
While “CODE_SET” is being displayed, press [
] key for
at least 1 second and enter the security registration mode.
3. Using [FM] / [AM] / [
] / [
] keys, enter the code.
[FM] key : Number up / [AM] key : Number down
[
] key : Cursor Right / [
] key : Cursor Left
4. Press [
] key for at least 3 seconds to display “RE-EN-
TER”. Then, re-enter the code using the method in above
No. “3”.
5. Press [
] key for at least 3 seconds to display “AP-
PROVED”.
6. Release the test mode. (Refer to the section on “How to
Release the Test Mode.”)
Note : The security code for this model cannot be deleted by
“all clear” command.

Method of clearing the programmable security
code (KDC-MP632U/X590)
1. While “– – – –” is being displayed, press [
] key for at
least 3 seconds while pressing [AUTO] or [TI] key.
This makes “– – – –” display disappear.
2. Using the remote controller, input “KCAR”.
Press remote controller [5] key 2 times (Input for “K”) and
then press [
] key.
Press remote controller [2] key 3 times (Input for “C”) and
then press [
] key.
Press remote controller [2] key once (Input for “A”) and then
press [
] key.
Press remote controller [7] key 2 times (Input for “R”) and
then press [
] key.
3. The security is released and the unit enters the STANDBY
mode.
4. If a wrong code is input, the unit goes into the Code Re-
quest mode.
