TEST MODE
1. How to enter the test mode
• Reset the unit while holding preset 1 key and preset 3
key.
2. How to exit from the test mode
• RESET
• POWER OFF
• ACC OFF
• Bu OFF
• Panel detach
3. Initial status in test mode
• Sources : ALL OFF
• Display : All segments are lit.
• Volume : -10 dB (displayed as 30)
• LOUD : OFF
• CRSC : OFF regardless of the presence of
switching function.
• SYSTEM Q : Flat
• BEEP : ON
• DEMO : OFF
4. Special display during Tuner mode
If the following display appears during the TUNER mode,
the front end is defective.
• "TNE2P NG": EEPROM remains in the initial value (don't
care) because the product is shipped without passing the
F/E adjustment process.
• "TNCON NG": Communication with the F/E is not
possible.
5. Forced switching of K3I
Every pressing of the Preset 6 key during the TUNER mode,
changes the status from Forced middle →Forced narrow
→AUTO →Forced wide →Forced middle.
When the product is set to the Forced middle: FMM in the
initial state, the following message appears.
• Forced middle : FMM
• Forced narrow : FMN
• AUTO : FMA
• Forced wide : FMM
6. Test mode specifications of the CD receiver
• Forced eject operation is prohibited during the reset start
mode. CD cannot be recognized when the product is reset
with CD remains inserted.
• Track jump takes place to the following track when the
Track up key is pressed.
No. 9 →No. 15 →No. 10 →No. 11 →No. 12 →No. 13
→No. 14 →No. 9 (The cycle restarts from here.)
• When the Track down key is pressed, track returns back
by one track during playback.
7. Audio system
• The product enters the audio adjustment mode when the
Q key is pressed momentarily.
• Continuous advance operation from remote control is
prohibited.
• The Bass/Middle/Treble is adjusted to either one of the 3
steps of MIN/Center/MAX with Track up/down key.
• Balance is adjusted to either one of the 3 steps of Left
MAX/Center/Right MAX with Track up/down key.
• Fader is adjusted to either one of the 3 steps of Rear
MAX/Center/Front MAX with Track up/down key.
• HPF (high-pass filer) is adjusted to either Through or 220
Hz with Track up/down key.
• LPF (low-pass filer) is adjusted to either Through or 120
Hz with Track up/down key.
• Bass f/Bass Q/Bass EXT/Middle f/Middle Q/Trable f do
not appear on the audio adjustment.
8. MENU system
• The product enters the MENU mode when the CLK key
is pressed momentarily.
• The product enters the MENU mode when the DNPP/
SBF key of the remote control is pressed.
• Continuous advance operation from remote control is
prohibited.
• The calendar adjustment, calendar display switching and
calendar memo are deleted from the advance operation.
(FL model)
• Red is set by the preset 1, blue by 2, green by 3 and
white by 4 in the color adjustment mode. (VCLD model)
• Contrast can be adjusted in 3 steps of 0/5/10. Initial value
is 5. (VCLD/VCLD model)
• Brightness can be adjusted in 3 steps of 0/5/10. Initial
value is 10. (Normal FL model)
9. Backup current measurement
If RESET is activated in the ACC OFF state (when BACKUP
button is turned ON), the MUTE terminal turns OFF in 2
seconds, not in 15 seconds. (At this time, the panel/CD/
TAPE mechanism does not operate.)

TEST MODE
2.Enter the security registration mode by pressing the CLK
key.
3.Enter the CODE by pressing the Track up/down and AM/
FM key.
Example: To enter "3510"
• Press the FM key four times.
• Press the Track up key once and the FM key six
times.
• Press the Track up key once and the FM key twice
times.
• Press the Track up key once and the FM key once
times.
• When the AM key is pressed, the codes are
searched in reversed direction. When Track down
key is pressed, the entry digits return.
4.When the DISP key is pressed for three seconds, the
message "RE-ENTER" appears. Then enter the code
referring to step 3.
5.Press the DISP key for three second so that the message
"APPROVED" appears.
6.Quit the test mode. (See item 2. How to quit the test
mode.)
(Note) The security code of this model cannot be all
cleared.
• Simple security code clear procedure (K type
only)
1.Press the VOL UP key longer for 3 seconds while pressing
the DISP key during requesting the code. (The message
---- disappears.)
2.Enter "KCAR" from remote control. (Same as the 00
model)
• Press the 5 key twice on remote control and press the
Track up key. (Enter "K".)
• Press the 2 key on the remote 3 times, then press the
Track Up key. (This enters "C".)
• Press the 2 key on the remote once, then press the
Track Up key. (This enters "A".)
• Press the 7 key on the remote twice, then press the
Track Up key. (This enters "R".)
3.The security is released and the product enters the ALL
OFF mode.
4.If incorrect code is entered by mistake, the product enters
the code-requesting mode.
10. Special display when the display is All ON
If the PRESET key is pressed while all displays are turned
on by ALL OFF, the following display appears.
PRESET 1
Version display (8 digits, Month/Day/Hour/Minute)

• Displays such as "CODE OFF" are not shown during
Power-ON.
• When the CLK key is pressed longer for 1 second during
ALL OFF, the product enters the MASK KEY (security)
write mode.
• The RESET-LOADING is not performed unless CD is
already caught in the CD/R mode.
■ Security-related information
• Forced Power ON mode (All models)
Even when security (MASK key) is enabled, the product
can be powered ON for 30 minutes only by pressing the
RESET key while both of the ATT key and the Preset 4
keys are being pressed. The product will recover only by
RESET if 30 minutes have elapsed.
