key for less than 1 second to clear the detection informa-
tion. (E2PROM clear)
4. DC offset error display mode is released by resetting. (What
was on the last screen will not be retained.)
●
FM/AM channel space switching (KDC-X790)
From the Power OFF condition, while pressing [1] and [5] keys
down simultaneously, press the [SRC] key and turn power ON.
●
Security
• Forced Power ON mode
While “– – – –” is being displayed, by resetting while pressing
[
] (NEXT) key and [4] key simultaneously, it is possible to
turn the power ON for 30 minutes only.
• Method of clearing the programmable security
code (KDC-X790)
1. While “– – – –” is being displayed, press [
] key for at
least 3 seconds while pressing [AUTO] key.
This makes “– – – –” display disappear.
2. Using the remote controller, input “KCAR”.
Press the remote control [5] key 2 times, display “K”, and
press the [
] key.
Press the remote control [2] key 3 times, display “C”, and
press the [
] key.
Press the remote control [2] key once, display “A”, and press
the [
] key.
Press the remote control [7] key 2 times, display “R”, and
press the [
] 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.
• How to register the security code on the “Car Au-
dio Passport” after replacement of the E2PROM
(F/E) (KDC-W8534/W8534Y)
1. Enter the test mode. (Refer to the section on “How to Enter
the Test Mode.”)
2. Enter the MENU by long pressing [
] (NEXT) key for one
second.
While “Security” 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.
DC OFFSET ERROR
●
Purpose
Prevent customers’ vehicle speakers damages, burnouts, and
smoking.
Avoid the connected speakers to be burned out, damaged, or
to smoke when DC occurs between the audio power amp. +
and - outputs.
●
Processing after detection
1. System status
• At the detection of DC error, error data is to be saved im-
mediately (E2PROM error log save area).
• Display the error message on the display. The system shall
maintain the current condition, including the operation. Shut
down audio system power supply. Set Mute to ON.
• Although switching between Power OFF and ON (ACC, BU,
and Key operation) is valid, switching from Off to ON shall
be error until the
µ
-com is reset.
∗
While power-on, even if the IC2VI DCErr output terminal
logic recovered to normal level value, the error condition
shall continue.
• Prohibit to save the backup/installer memory to E2PROM
(nonvolatile memory).
2. Controlling
µ
-com terminal
• Set Mute for all channels including for pre-out.
• Turn off power IC control system power supply. (Set AMP-
Standby function to valid)
• Set P-Con output to OFF (Logic by which external AMP
unit is turned off).
