TEST MODE

●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.

•Display lights are all turned on.

•The volume is at 30 (-10dB).

•LOUD is OFF.

•CRSC is off regardless of the availability of switching function.

•SYSTEM Q is NATURAL (=FLAT).

•BEEP should always function when the key is pressed briefl y.

•AUX is ON (Internal AUX supporting model).

●Speciication of the test mode for tuner sourse

The frequency of 98.3MHz is received when the [4] key is pressed in the TUNER FM mode

●Specification of FST soft mute adjustment mode

1.Receive the TUNER FM mode in the VOLUME 30 and LOUD OFF condition.

2.Press and hold the [ ] key for 2 seconds to enter the FST soft mute adjustment mode.

3.In the adjustment mode, the following display is shown. Adjust the mute between 0 (18dBu) and F (36dBu) with the [FM] / [AM] keys.

(Display) SMD–x_ _ _ (Adjustment value, 0~F is displayed in “x”).

4.When the adjustment is “OK”, press and hold the [ ] key for 2 seconds again to write the adjustment value in the E2PROM, and after the successful writing-in the “EP_WRITE” is displayed.

5.Press the [ ] key briefl y to exit from the FST soft mute adjustment mode.

(The test mode continues.)

OFF the P-CON terminal. ( The symbol, “_” indicates the blank. )

→Make this as the process dedicated for the test mode. P-CON is recovered by Power OFF→ON.

●Special display in tuner mode

Error is found in front-end, etc. if indications below are displayed while in tuner mode.

•“TNE2P_NG” : E2PROM (in front-end: A500 of X34-) values are still default (not determined)

•“TNCON_NG” : Cannot communicate with the front-end.

●K3I forced switching

Every time when [6] key is pressed in tuner FM mode,

switched in the following order: AUTO→Forced WIDE

→Forced MIDDLE→Forced NARROW→AUTO. Default status is AUTO, and displayed as shown below.

•	AUTO: FM1_98.1A	• Forced WIDE: FM1_98.1W
•	Forced MIDDLE: FM1_98.1M	• Forced NARROW: FM1_98.1N

● CD source test mode specification

•Display mode default setting shall be P-TIME.

•Jumps to the following tracks by pressing the [ ] key. No.9→No.15→No.10→No.11→No.12→No.13→No.22→ No.14→No.9 (recursive)

Note that when playing a CD-DA disc and MP3 / WMA / AAC / WAV discs with 8 fi les or less, the disc is played from the 1 track in the normal order.

•Pressing the [ ] key goes back by 1 track from the track being played.

•When playing an MP3 / WMA / AAC/WAV disc, display the fi le format before starting to play each fi le.

( “MP3”, “WMA”, “AAC”, “WAV” )

•While in CD source, press the [1] key briefl y to jump to No.28.

•While in CD source, press the [2] key briefl y to jump to No.14.

•While in CD source, press the [3] key briefly to display CD mechanism model name and the version.

INSTALLER MEMORY SPECIFICATIONS

At specialists (or specialty stores), when the installer sends the vehicle back to the user, they may make the storerecommended audio confi guration.

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 confi guration values can be saved into E2PROM.

The specification detail defer in “with-DSP model” and in “without-DSP model”.

[Models without DSP]

•Calling and saving the configuration is done by the MENU.

•Items to be saved are Bass, Middle, Treble, X’over, and Sub Woofer Level. 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 specifi cation, 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 refl ected 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 refl ected.

(Bass/Middle/Treble setting initial setting value memory is refl ected 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 refl ected.

•In models which includes channel space switching, when channel space is switched, TUNER-preset frequencies are set back to the default values.

DC OFFSET ERROR

●Purpose

Prevent customer’s 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

•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).

•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.

•Key specification

•Other keys than eject and power keys are invalid.

•Display specification

•Display the “PROTECT” string and blink all characters at 1Hz.

Use the indication below with the highest priority (error message), and maintain the error message even when the source is changed.

Display example

		Blink
PROTECT	alternately
		at 1Hz

● 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).

•If DC error is detected during the capacitor leak detection period, the clearing the error by the reset is limited to 4 times.

The startup is inhibited for the 5th time and later reset. ("PROTECT" display has to be blinked.)

● Note while in the test mode

•While in the test mode, even if DC leak is detected, it is not written into E2PROM.

When an error is detected, the display is enabled.

● Other

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