TEST MODE

1. How to enter the test mode

While holding the FM and Preset 6 keys, reset the unit.

2. How to exit from the test mode

While holding the Preset 6 key, reset the unit.

(Note) The test mode cannot be terminated by ACC OFF,

power OFF or 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

• LED : White for no scanning. (VLCD model)

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 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. 14 → No. 9

(The cycle restarts from here.)

• Each press of the Track Down key jumps to the previ-

ous track number to the track being played.

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.

• Continuous holding of a remote control key is inhibited.

• Bass, Middle and Treble 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/220 Hz with the

Track Up/Down keys.

• LPF is adjusted in 2 steps of Through/120 Hz 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 adjustment.

8. Menu-related specifications

• A short press of the CLK key initiates the Menu mode.

• Pressing the DNPP/SBF key on the remote initiates the

Menu mode.

• Continuous holding of a remote control key is inhibited.

• Calendar adjustment, calendar display switching and

calendar memo are eliminated from the targets of con-

tinuous key holding. (FL model)

• In the color adjustment mode, pressing the Preset 1 key

sets Red, 2 sets Blue, 3 sets Green and 4 sets Green.

(VLCD model)

• Contrast is adjusted in 3 steps of 0/5/10 and the default

is 5. (VLCD/LCD model)

• Brightness is adjusted in 3 steps of 0/5/10 and the

default is 10. (Normal FL model)

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 panel, CD mechanism and

TAPE mechanism are not activated at this time.)

10. Special display when the display is all on

Pressing the Preset keys while the power is ALL OFF dis-

plays the following information.

Version display (8 digits, Month/Day/Hour/Minute)

inhibited. (M&T model)

• Panel operation by turning power OFF/ON is inhibited.

(M&T model)

• Messages such as "CODE OFF" are not displayed

when power is turned ON.

• Pressing the ATT key opens or closes the panel. (M&T

model)

• Pressing the TI (AUTO) key during changer operation

• Security-related information

1. Forced Power ON mode (All models)

Even when the security (Mask key) 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)

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

mode")

(2) Press the CLK key to enter the security registration

mode.

(3) Enter the code using the Preset 1/2/3/4 keys.

Example: To enter "3510"

• Press the Preset 1 key 4 times.

• Press the Preset 2 key 6 times.

• Press the Preset 3 key twice.

• Press the Preset 4 key once.

(4) Press and hold the DISP key for 3 seconds until

"APPROVED" is displayed.

(5) 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 Type

only)

(1) While the code entry is requested, press and hold the

VOL UP key for 3 seconds while holding the DISP

key pressed. (This should turn "----" off.)

(2) Enter "KCAR" from the remote. (Same way as the 00

model)

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

Track Up key. (This enters "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 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.

4. Method of writing the Mask key while the EEPROM is in

the initial status

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

mode")

(2) Press the CLK key to enter the Mask key registration

mode. "TRANSMIT1" should be displayed now. The

display at this time should show " < > " in place of " [ ]

(3) Point the Mask key remote toward the light sensor,

and press and hold its key for more than 0.5 second.

(4) When "TRANSMIT2" is displayed, press and hold the

key on the Mask key remote for more than 0.5 second

again. The first and second counter codes are not

compared at this time.

(5) When "APPROVED" is displayed, the write operation

is complete. Now the demonstration mode is initiated

and the test mode is terminated.

(Note) In the same way as previous models, if 30 minutes

have elapsed with no code written, an error occurs

and the power is turned OFF.

5. Method of initializing the Mask key

(How to reset the unit from the Mask key approved condi-

tion to the factory condition)

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

mode")

(2) "TRANSMIT1" is displayed and the Mask key entry

request mode is initiated.

The display at this time should show " ∗ ∗ " in place of

" [ ] ".

(3) Press and hold the key on the Master key remote for

more than 3 seconds.

(4) When "TRANSMIT2" is displayed, press and hold the

key on the Master key remote for more than 3 sec-

onds again.

(5) When "APPROVED" is displayed, the Mask key is

cleared, the demonstration mode is initiated, the test

mode is terminated and the unit returns to the factory

condition.

6. Method of clearing all Mask key-related data

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

mode")

(2) Press the CLK key to enter the Mask key registration

mode. "TRANSMIT1" should be displayed now.

(3) Point the Master key remote toward the light sensor,

and press and hold its key for more than 3 seconds

(until the level display shows the full condition).

(4) When "TRANSMIT2" is displayed, hold the key on the

Mask key remote for more than 3 seconds again.

If "TRANSMIT1" is displayed in place of "TRANS-

MIT2", restart the procedure from step (3).

(5) When "APPROVED" is displayed, all security data is

cleared and the unit returns to the condition before

Mask key writing with the EEPROM in the initial sta-

tus.
