TEST MODE

1. How to enter the test mode

• While holding the preset 1 key and 3 keys, reset the unit.

2. How to exit from the test mode

• Reset the unit, ACC OFF, power OFF, and come off the
front panel assy for the unit.

3. Initial status in the test mode

• Sources : All OFF.

• Display : All segments were lit.

• Volume : -10 dB (displayed as 30)

• Loudness : OFF

•CRSC : OFF regardless of the presence of

switching function.

• SYSTEM Q : Flat.

• Aux : ON

• Display color : white (variable color display model only)

• Beep sound : ON

4. Special display in Tuner mode

When any of the following messages is displayed in Tuner

mode, the Front-end (F/E) may be bad condition.

• "TNE2P NG": The EEPROM is set to the default (unstable
values) because the F/E was shipped without passing
through the adjustment process, etc.

• "TNCON NG": Communication with the F/E to micro­processor is not possible.

5. Forced switching of K3I

Each press of the Preset 6 key in Tuner mode should
switch K3I from AUTO → Forced Wide → Forced Middle →
Forced Narrow → AUTO. The initial status is AUTO and
the display shows these modes as follows.

• AUTO : FMA

• Forced Wide : FMW

• Forced Middle : FMM

• Forced Narrow : FMN

6. Test mode specifications of the CD receiver

• Forced ejection is inhibited in the reset start operation.
When the unit is reset while a CD is loaded in it, the CD is
not recognized by resetting.

• Each press of the Track Up key jumps to the following
track numbers:
No. 9 → No. 15 → No. 10 → No. 11 → No. 12 → No. 13 →
No. 22 → No. 14 → No. 9 (The cycle restarts from here.)

• Each press of the Track Down key jumps to the previous
track number to the track being played.

• When the number of total tracks of an MP3 disc is nine or
less, unit playback from a track 1.

• When the media to CD-DA, unit playback from track No.28
by key operation of preset 1 key.

7. Audio-related specifications

• A short press of the Q key initiates the audio adjustment

mode.

• Pressing the

✽ key on the remote initiates the audio ad-

justment mode.

• Continuous holding of a remote control key is inhibited.

• Bass, Middle and Treble are adjusted in 3 steps of -8 / 0 /
+8 with the Track Up/down keys (default is 0).

• Balance is adjusted in 3 steps of Left L15 / 0 / R15 Max
with the Track Up/down keys (default is 0).

• Fader is adjusted in 3 steps of Rear15 / 0 / F15 Max with
the Track Up/down keys (default is 0).

• HPF is adjusted in 2 steps of Through/170Hz (or 200Hz)
with the Track Up/down keys (default is through).

• LPF is adjusted in 2 steps of Through/120Hz with the Track
Up/down keys (default is through).

• Bass f, Bass Q, Bass EXT, Middle f, Middle Q and Treble
f are not dealt with by the audio adjustment.

8. Menu-related specifications

• A short press of the PLAY/PAUSE key initiates the Menu

mode.

• Pressing the DNPP key on the remote initiates the Menu

mode.

• Continuous holding of a remote control key is inhibited.

• Contrast is adjusted press of the Track up/down key in 3
steps of 0 / 5 / 10 (default is 5).

9. Backup current measurement

When the unit is reset while ACC is OFF (i.e. by turning
Backup ON), the MUTE terminal goes OFF in 2 seconds in
place of 15 second. (The CD mechanism is not activated at
this time.)

KDC-3022,322,5023/R,5024/V/Y/YV,507,5094RY

TEST MODE

10. Special display when the display is all on

Pressing the Preset keys while the power is ALL OFF dis­plays the following information.

11. Change the condition of TUNER channel
space selection (K/M type only)

While holding the preset 1 key and 5 keys, reset the unit.

Security-related information

1. Forced Power ON mode (All models)

Even when the security is approved, resetting the unit while
holding the Q and Preset 4 keys makes it possible to turn
the power ON for 30 minutes.
After 30 minutes have elapsed, it is not possible to return to
the previous condition unless the unit is reset again.

2. Method of registration of the security code

after EEPROM (Tuner unit assy) replacement
(Code security model)

1. Enter the test mode. (See 1. How to enter the test mode)

2. Press the MENU key to enter the MENU mode.

3. Press and hold down the Track up/down key for 1 second
until “Security” is displayed.

4. Enter the code using the FM/AM/TARCK up/down keys.

• FM key: number is up

• AM key: number is dawn

• Track up key: move the cursor for right side

• Track down key: move the cursor for left side

5. Hold down the Track up key for at least 3 seconds and
the message, "RE-ENTER" appears, so once again enter
the code according to Step 3 above.

6. Press and hold the Track up key for 3 seconds until
"APPROVED" is displayed.

7.

Exit from the test mode. (See 2. How to exit from the test mode)

(Note) All Clear is not applicable to the security code of

this model.

3. Simplified method of clearing the security
code (K, E Type only)

1. While the code entry is requested, press and hold the
TRACK UP key for 3 seconds while holding the DISP key
pressed. (This should turn "----" off.)

2. Enter “KCAR “from the remote.

• Press the 5 key on the remote twice, and then press the

Track Up key. (This enters "K".)

• Press the 2 key on the remote 3 times, and then press

the Track Up key. (This enters "C".)

• Press the 2 key on the remote once, and then press the

Track Up key. (This enters "A".)

• Press the 7 key on the remote twice, and then press the

Track Up key. (This enters "R".)

3. The security code is cleared and the unit enters the ALL
OFF mode.

4. If you commit a mistake in the code entry, the unit enters
the code request mode again.
