TEST MODE
●How to enter the test mode
While pressing and holding the Preset 1 and Preset 3 keys,
reset the unit.
●How to exit from the test mode
While holding the Preset 6 key, reset the unit.
(Note) The test mode cannot be terminated by reset the
unit, ACC OFF, power OFF and Panel detached, momen-
tary power down.
●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 func-
tion.
• SYSTEM Q : Flat
• WOW : All OFF
• BEEP :When pressing any keys, the buzzer generates a
beep at any time.
• AUX : ON
• MENU SYSTEM Q : OFF
• Variable model : Default is white
• Multifunction : Source dependency (Preset, SCAN, etc.)
●Special display inTuner mode
When any of the following messages is displayed inTuner
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.
●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
• Forced Wide : FMW
• Forced Middle : FMM
• Forced Narrow : FMN
●Test mode specifications of the CD receiver
• Forcedejection isinhibited inthe resetstart operation. When
the unit is reset while a CD is loaded in it, the CD is not
recognized by resetting.
• Each press of theTrack 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 trucks of the MP3 disc or the
WMA disc is less than 9, 1st truck is played.
• When the disc media is CD, A short press of the Preset 1
key jumps to the track number 28.
• 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 FL model is
lower stand and Display mode of LCD model is DNPS.
●Audio-related specifications
• Pressing the ✽key on the remote initiates the audio adjust-
ment mode.
• BL/F key on the Fader initials.
• Continuous holding of a remote control key is inhibited, and

• Do not write the serial with the serial writing jig on the test
mode.
• OEM display output is not stop if OEM display not connec-
tion on the test mode.
●Switching the frequency span (K/M type)
While holding the Preset 1 key and Preset 5 key, reset the

●Security-related information
1. Forced Power ON mode (All models)
Even when the security (Cord) is approved, resetting the
unit while holding the Q and Preset 4 keys makes it pos-

TEST MODE
2. Method of registration of the security code after
EEPROM (F/E) replacement (Code security model)
1) Enter the test mode. (See How to enter the test mode)
2) Press the MENU key to enter the Menu mode.
3) When the message “Security” is displayed, press and hold
the Track Up/Down key for 1 second to enter the security
registration 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 theTrack 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 1) All Clear is not applicable to the security code of
this model.
(Note 2) When the F/E changed, need re-inscription be-
cause the panel security is clear.
3. Simple way to clear the security code (K type only)
1) During code request mode, press the Track UP key for at
least 3 seconds while holding down the AUTO key.(– – – –
will disappear)
2) Enter, “KCAR” with the remote controller as described be-
low.
• Press the remote controller 5 key twice, and press the
Track Up key. (Enters a “K”)
• Press the remote controller 2 key three times, and press
the Track Up key. (Enters a “C”)
• Press the remote controller 2 key once, and press the
Track Up key. (Enters an “A”)
• Press the remote controller 7 key twice, and press the
Track Up key. (Enters an “R”)
3) Security function is canceled and unit sets to All-Off mode.
4) Code request mode appears if a mistake was made in en-

4. How to inscription the panel security code
1) Enter the test mode.
2) Pressing theAM keyon alllighting, check the“P-ROMWAIT”
display.
3) The NEXT key is long press 2 seconds, writing the code.
4) Display is “P-ROM OK”.
5) Exit from the test mode.
(Note) E2PROM connection is NG when display is “P-ROM
NG”, so detach the panel and rewrite after the display is “P-
ROM WAIT”.This code can not clear.
●Check the SRAM
Output (Hi) to the SRAM_CHECK terminal on 101 pin when
SRAM is function properly on the panel of 4 gradation FL
models.
●Check the Flash ROM
1) Display to the following effect at ALL OFF by assortment
system computer and panel for cover the customization
model attach the panel with no Flash ROM.
• Customization system computer + Flash ROM panel :All
lighting
• Non customization system computer + Non Flash ROM
panel : All lighting
• Customization system computer + Non Flash ROM panel
: Panel NG
• Non customization system computer + Flash ROM panel
: Panel NG
2) Output (Hi) to the FLASHROM_CHECK terminal on 102
pin when Flash ROM is function properly.
3) Flash ROM data is initialized when pressing the AM key
long hold at all lighting.
Display is “Data Erase ....” in data erasing mode. Do not
touch anything this mode.When the data erase completed,
display is “Erase OK!!”.
If display is “Erase NG!!!!!!”, Flash ROM data unable erase
for some kind or another factors.
When same effect as pressing the AM key long hold and
data erase once again, Flash ROM is defective.
