TEST MODE
1. How to enter the test mode
While pressing and holding the Preset 1 and Preset 3 keys, re-
set the unit.
2. How to exit from the test mode
Reset the unit, ACC OFF, power OFF and Panel detached.
(Note) The test mode cannot be terminated by momentary
power down.
3. Initial status in the test mode
• Sources : ALL OFF
• Display : All segments are lit.
• Volume : -10 dB (displayed as “30” )
• Loudness : OFF
• CRSC : OFF regardless of the presence of switching
function.
• SYSTEM Q : Flat
• BEEP : When pressing any keys, the buzzer generates
a beep at any time.
4. Special display in Tuner mode
When any of the following messages is displayed in Tuner mode,
the F/E may be abnormal.
• “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 is not possible.
5. Forced switching of K3I
Each press of the Preset 6 key inTuner 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
• ForcedWide : 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 recog-
nized 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.
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 trucks of the MP3 disc or the WMA
disc is less than 9, 1st truck is played.
• When the model is equipped the CD mechanism assembly
adapted for MP3 or MP3/WMA disc, the mechanism name and
version number are displayed during the CD source selecting.
• When the disc media is CD, A short press of the Preset 1 key
jumps to the track number 28.
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 adjustment
mode.
• Fader is selected to the initial item.
• Continuous holding of a remote control key is inhibited.
• Bass, Middle andTreble are adjusted in 3 steps of Min / Center
/ Max with the Track Up/Down keys.
• Balance is adjusted in 3 steps of Left Max / Center / Right Max
with the Track Up/Down keys.
• Fader is adjusted in 3 steps of Rear Max / Center / Front Max
with the Track Up/Down keys.
• HPF is adjusted in 2 steps of Through / 220Hz with the Track
Up/Down keys.
• LPF is adjusted in 2 steps of Through / 120Hz with the Track
Up/Down keys.
• Bass f, Bass Q, Bass EXT, Middle f, Middle Q and Treble f are
not dealt with by the audio adjust.
8. Menu-related specifications
• Pressing the DNPP/SBF key on the remote initiates the Menu
mode.
• Continuous holding of a remote control key is inhibited.
• In the case of the CD receiver model, A short press of the
PLAY/PAUSE key initiates the Menu mode.
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.)
10.Special display when the display is all on
Pressing the Preset keys while the power is ALL OFF displays
the following information.
[PRESET 1] Version display (8 digits, Month/Day/Hour/Minute)
(Display)SYS xxxxxxxx : System microcomputer
PAN xxxxxxxx : Panel microcomputer
[PRESET 2] Sireal number display (8 digits)
(Display) SNo xxxxxxxx
[PRESET 3] Short press :View power ON time. (The All OFF
period is not counted.)
Long press/hold : Clear power ON time at the
power ON time displaying.
(Display) PonTim xxxxx Max. 65535 (hours)
[PRESET 4] Short press : Display CD operation time.
Long press/hold : Clear CD operation time at the
CD operation time displaying.
(Display) CDTime xxxxx Max.65535 (hours)
[PRESET 5] Short press : Display CD ejection count.
Long press/hold : Clear CD ejection count at the
CD ejection count displaying.
(Display) EjeCnt xxxxx Max. 65535 (times)
[PRESET 6] Short press : Display Panel open/close count.
Long press/hold : Clear Panel open/close count
at the Panel open/close count.
(Display) PnCnt xxxxxx Max.655350 (times)

11. Method of the span switching (K and M type only)
While holding the Preset 1 and Preset 5 keys, reset the unit.
12. Other specifications
• No displays such as “CODE OFF” during Power-ON.
• Pressing theTI (AUTO) key during changer operation turns on
2zone. Cancel by pressing the TI (AUTO) key again.The P/S
dot is lit during 2zone.
• In the case of 2 PREOUT model with Non Fader output, Each
pressing and holding the ATT key for 1 second or more during
All OFF, Non Fader output is switching Rear output or Non
Fader output.
• In the case of 2 colors key illumination model, Each press the
ATT key during All OFF, the key illumination is switching Green
or Red.
• Security-related information
1. Forced Power ON mode (All models)
Even when the security (Cord) is approved, resetting the unit
while holding the ATT 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 Ass'y) replacement (Code security model)

2.Press the PLAY/PAUSE key to enter the Menu mode.
3.When the message “Security” is displayed, press and hold
theTrack Up/Down key for 1 second to enter the security reg-
istration mode.
4. Enter the code using the FM/AM/Track Up/Track Down keys.
• FM key: Number up
• AM key: Number down
• Track Up key: Cursor right shift
• Track Down key: Cursor left shift
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 4 above.
6.Press and hold the Track Up key for 3 seconds until “AP-
PROVED” 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. Simple way to clear the security code (K type only)
1.During code request mode, press the VOL UP key for at least
3 seconds while holding down the DISP key. (---- will disap-
pear)
2.Enter, “KCAR” with the remote controller as described below.
(Same as on 01 model.)
• Press the remote controller 5 key twice, and press theTrack
Up key. (Enters a “K” )
• Press the remote controller 2 key three times, and press the
