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) (Code security models: E, M type)
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.
TEST 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).
∗
The purpose is to shut down audio output. Basically, the
logic sets the audio output system signal line when in
Standby source.
3. Key specification
• No specific limitation (Normal operation).
4. Display specification
• Display the “PROTECT” string and blink all characters at
1Hz.
∗
Use the indication below with the highest priority (error mes-
sage), and maintain the error message even when the
source is changed.
