SERVICE MANUAL

A unique identification number (Unique ID) is given to each unit, which is imprinted on the CD mechanism assembly. If and when the mechanism assembly or Flash ROM (IC17) on the mechanism board is replaced, it is necessary to write the Unique ID. For details, refer to "How to Write the Unique ID" on Page 17.

TEST MODE

KDC-W808/X689

● How to enter the test mode

In order to enter the test mode, reset the unit while simultaneously pressing down [1] and [3] keys.

● How to clear the test mode

Resetting only.

● Initial conditions of the test mode

• Source is STANDBY.

• Displays lights are all turned on.

• The volume is at -10dB (The display is 30).

• Loudness (LOUD) is OFF.

• CRSC is OFF, regardless of whether there are switching functions or not.

• SYSTEM Q is NATURAL (= FLAT).

• BEEP will sound anytime with a short push.

•Auxiliary (AUX) is ON.

• DISPLAY TYPE is TYPE C

• TUNER source display will be as follows <E type> Upper column = PS/Frequency,

Middle column = Spectrum analyzer, Lower column = Indicator

<M / K type> Upper column = SNPS,

Middle column = Spectrum analyzer, Lower column = Indicator

• CD source display will be as shown below. <E / K type> Upper column = P-TIME,

Middle column = Spectrum analyzer, Lower column = Blank

• SWPRE is SUB WOOFER ( 2 PREOUT models ).

● RDS automatic measurement

Conventionally, the PS display has been visually checked on the production line. This will be replaced by a new processing. The PS data will be received and the PS contents is to be verified as “RDS_TEST.”When this is v erified, the P-CON terminal is forced to go OFF. ( In this case, “_” means blank.)

→This will be a dedicated test mode processing.

On the P-CON, when power is turned off once and, then, turned on again, (Power OFF → ON ) the unit will be restarted.

● Special display when set to TUNER

When in TUNER mode, if an y of the f ollowing displa ys appear, there is an abnormality with the front end.

• “TNE2P_NG” : The E2PROM is still with the default (unspecified) value, due to the fact that the front-end being shipped without going through the adjustment process.

• “TNCON_NG” : In this condition, the communication with

the front end is not possible.

● Forced switching of K3I

In TUNER FM mode, each time [6] key is pressed, the functions move in the following cycle : AUTO → forced WIDE → forced MIDDLE → force NARROW → AUTO. The initial con- dition is AUTO and the displays below will appear.

•AUTO : FMA • Forced WIDE : FMW

•Forced MIDDLE : FMM • Forced NARROW : FMN

● CD receiver test mode specifications

•Jumps are made to the following trac ks by pressing the [ ] key .

No.9 → No.15 → No.10 → No.11 → No.12 → No.13 →

No.22 → No.14 → No.9 (Returns to the beginning) It must be noted, however, that when paying MP3/WMA/ AAC disk, which contain 8 files or less, the first trac k and the following tracks are played in order.

•When [ ] key is pressed, it goes down by one track.

• When a CD is used as a source, by short-pressing [1] key , a jump to the Track No.28 is made.

• When a CD is used as a source, by short-pressing [2] key , a jump to the Track No.14 is made.

• When a CD is used as a source, by short-pressing [3] key, the model name and the version of CD mechanism will be displayed in the upper column. When the [3] key is short pressed again, normal display will resume. (Time Code display.)

• When a CD is used as a source, by short-pressing [6] key , a jump to the Track No.15 is made. At the same time, the volume value is set to 25 (2V PRE) and 27 (5V PRE).

● Audio Adjust mode

• By short-pressing [AUD] key, the Audio Adjust mode is entered.

• As with the [AUD] key, [*] key on the remote controller can be used to enter the Audio Adjust mode.

• As for the adjustment items, items for both the A UDIO FUNCTION MODE and SETUP MODE are included.

• The first item is the Fader which is followed b y : Balance → Bass Level → Middle Level → Treb le Level → ( Sub W oofer Level ) → HPF Front → HPF Rear → LPF Sub Woofer. (After this, any of the item can be selected) * Normally, Sub Woofer Lev el is not included. In this version,

however, the Sub Woofer Level is included, and this has been already arranged.

• With the remote controller, continuous forwarding is prohibited.

• Using the VOL knob, the Fader is to be adjusted to the fol-

lowing three levels : R15 ↔0 ↔ F15. (The default value : 0)

• Using the VOL knob, the Balance is to be adjusted to the following three le v els : L15 ↔ 0 ↔ R15. (The default value :

• Using the VOL knob, Bass/Middle/Treble Level is to be adjusted to the following three levels : -8 ↔ 0 ↔ +8. (The default value : 0)

• Using the VOL knob , the Sub Woofer Lev el is to be adjusted to the following three levels : -15 ↔ 0 ↔ +15. (The default value : 0)

• Using the VOL knob, the Volume Offset is to be adjusted to the following two levels : -8 ↔ 0. (The default value : 0)

• Using the VOL knob, the HPF Front/Rear is to be adjusted to the following two levels : Through ↔ 180Hz (or 220Hz ). (The default value : Through)

• Using the VOL knob, the LPF Sub Woofer is to be adjusted to the following two le v els : 60Hz (or 50Hz) ↔ Through. (The default value : Through)

• Using the VOL knob, the Sub Woofer Phase is to be adjusted to the following two levels : Reverse ↔ Normal. (The default value : Normal)

•Volume Offset is the VOL knob and it is adjusted to the following 2 levels : -8 ↔ 0. (The default value is 0)

• Using the VOL knob, the Loudness ON/OFF is to be adjusted to the following two levels : OFF ↔ ON. (The default value : OFF)

• Using the VOL knob, the 2 Zone ON/OFF is to be adjusted to the following two levels : OFF ↔ ON. (The default value : OFF)

• Items of Bass f/Bass Q/Bass EXT/Middle f/Middle Q/T reble f are not included in the audio adjustment.

● MENU Items

• By short-pressing [EQ] key, MENU can be entered.

• The [DNPP/SBF] and [DIRECT] keys on the remote controller can also be used to enter the MENU.

• With the remote controller, continuous forwarding is prohibited.

• When a CD is used as a source, the default item will be the F/W Version.(DXM-6800 mechanism installed models.)

● 2-ZONE Items

• When using sources other than the STANDBY source, using a short-press on [AUTO]/[TI] key, 2-ZONE ON/OFF is achieved.

● Backup Current Measurement

When reset in Acc OFF (Back Up ON) condition, MUTE terminal goes off after 2 seconds, instead of 15 seconds. (During

this time, the CD mechanism does not function. The MASK mechanism will not function from the OPEN condition.)

● OPEL Communication Items

During the test mode, OPEL communication line outputs the following (At e very 500msec, the output condition of the communication line will be switched.)

● Special display when all lights are on

When all lights are on with the STANDBY source, the following displays are made when the keys sho wn below are pressed.
