Processing after detection
1. System status · At the detection of DC error, error data is to be saved immediately (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 AMPStandby 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.

Cancel Condition
· Press the Reset terminal on the main body. or set Backup to OFF (Unplug and plug back in the DC connector). The history is maintained (E2PROM data is saved).

Note while in test mode

· Function for checking and clearing data in E2PROM by a given key shall be included. (Used at production dpt. and service center, etc.)

CD LOAD ERROR DETECTION
Overview
Record the number of times when mechanism error (SW error) occurred at CD LOAD. LOAD error recording shall be done in 2 patterns, by the SW status illustrated below. LOAD error is established when LOAD operation is not completed after LOAD operation is started before the protect timer count is completed. Clearing of record is done in the following situations: 1) After reset is cancelled, when reading EEPROM, the code is NG. 2) While in test mode, the specified key (Play/Pause key pressed for 2 seconds) input. 3) When in EEPROM all-clear initialization mode (refer to the test mode specification document) · Display is shown on the test mode specification document. · Number of times with error(s) is 99 at MAX. · Not recorded in test mode [1+3 keys].

CD LOAD ERROR DETECTION
Operation
LOAD
SW1 (LOS SW) SW3 (12EJE SW) SW4 (LOE/LIM SW) ERR condition LOAD_ERR1 LOAD_ERR2 Special case w q

q If the protect timer was counted up before the LOS (SW1) up edge detection, it is recorded as LOAD_ERR1. w If the protect timer was counted up after the LOS (SW1) up edge detection, before the LOE/LIM (SW4) up edge detection, it is recorded as LOAD_ERR2. When DISC was inserted briefly but pulled out immediately (DISC is detected but not inserted), it is considered as an error. Special case: Even if LOS (SW1) up edge is not detected, if LOE/LIM (SW4) up edge is detected, it is still recorded as LOAD_ERR1. Also, if SW4 up edge is detected, the motor is stopped.

Trigger for starting the sequence: detecting the inserted disc with SW 1 and 3 LOW edge. (As an exception, protect LOAD when EJECT error)

CD EJECT ERROR DETECTION
Overview
Record the number of times when mechanism error (SW error) occurred at CD EJECT. EJECT error recording shall be done in 4 patterns, by the SW status illustrated below (3 patterns in models other than TYPEJ). EJECT error is established when EJECT operation is not completed after EJECT operation is started before the protect timer count is completed (False EJECT, or ejection with no CD, is considered as exception and is not recorded). (False EJECT is determined when: while chucking is not done, and when SW status is determined as NO DISC.) Clearing of record is done in the following situations : 1) After reset is cancelled, when reading EEPROM, the code is NG. 2) While in test mode, the specified key (Play/Pause key pressed for 2 seconds) is input. 3) When in EEPROM all-clear initialization mode (refer to the test mode specification document). · Indication is shown on the test mode specification document. · Number of times with error(s) is 99 times at MAX. · Not recorded in test mode [1+3 keys]. · When EJECT was error, re-try 3 times, and count each error while re-try as 1 error.

Trigger for starting the sequence: detecting DISC ejection by EJECT key. (As an exception, protect EJECT when LOAD error) q If the protect timer was counted up before the LOS (SW1) down edge detection, it is recorded as EJECT_ERR1. w If the protect timer was counted up after LOS (SW1) down edge before the 12EJE (SW3) down edge detection, it is recorded as EJECT_ERR2. r If the protect timer was counted up after LOS (SW1)/12EJE (SW3) down edge before the down edge detection of any of these, it is recorded as EJECT_ERR4. When EJECT is started, if not chucking, it is not counted as EJECT error (considered as false EJECT). However, EJECT when SW change is detected.

INSTALLER MEMORY SPECIFICATIONS
At specialists (or specialty stores), when the installer sends the vehicle back to the user, they may make the store-recommended audio configuration. When the user changes the setting values, when the backup power supply was taken out at times of battery change or when the reset button was pressed, to make it possible to recall the setting values, the store-recommended configuration values can be saved into E2PROM. The specification detail defer in "with-DSP model" and in "without-DSP model". · Calling and saving the configuration is done by the MENU. · Items to be saved are Bass, Middle, Treble, X' over, and Sub Woofer Level (Refer to the separate document for more detail). Only one setting can be saved for each item (Bass/ Middle/Treble settings can be changed for each source, but only one setting can be saved as the installer memory specification, and the source in which the saving operation was carried out is saved as such). · The contents read out by the call key shall be reflected only to the current source at the time EQ curve is "USER" (Bass/Middle/Treble settings can be changed for each source, but not reflected to Bass/Middle/Treble settings of sources other than where the calling operation was carried out). · When the backup power supply was taken out at times of battery change or when the reset button was pressed, as the initial setting values of Bass, Middle, Treble, X' over, and Sub Woofer Level, the saved memory is reflected. (Bass/Middle/Treble setting initial setting value memory is reflected in all sources.) NOTE: By such, EQ curve initial setting shall always be "USER" (NOT "NATURAL" or "FLAT").

BACKUP MEMORY SPECIFICATIONS
Settings by the user other than the installer memory items are saved into the E2PROM, and when the backup power supply was taken out at times of battery change or when the reset button was pressed, it is made possible to recall the setting values saved. · While Power ON, the memory is saved and accumulated at a certain interval (temporary). · Items to be saved into the memory are: Volume Offset (for all sources) and preset frequencies (FM/AM all bands x 6 channels). · When the backup power supply was taken out at times of battery change or when the reset button was pressed, as the initial setting values of Volume Offset (for all sources) and preset frequencies (FM/AM all bands x 6 channels), the saved memory is reflected. · In models which includes span-switching, when span is switched, TUNER-preset frequencies are set back to the default values.
