1. How to enter the test mode While holding the Preset 1 and Preset 3 keys, reset the unit.

2. How to exit from the test mode Reset the unit, momentary power down, ACC OFF, power

OFF, and Panel detached. (Note) The test mode cannot terminated by Panel is fall

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. DISPLAY TYPE: TYPE A

4. RDS automatic measurement An addition to disposal of substitute for visual check PS

display as usual production lines. P-CON terminal is OFF by force, when received the PS

data and in case of corrobaration PS display isRDS_TEST. (_ is mean blank.)

This disposal is test mode only. P-CON is switching the source or return with power onoff.

5. Special display in Tuner modeWhen any of the following messages is displayed in Tunermode, the front end may be abnormal.

TNE 2P NG: The EEPROM is set to the default (unstablevalues) because the F/E was shipped without passingthrough the adjustment process, etc.

TNCON NG: Communication with the F/E is not possible.

6. Forced switching of K3I Each press of the Preset 6 key in Tuner mode should switch

K3I from AUTO Forced Wide Forced Middle ForcedNarrow AUTO. The initial status is AUTO and the dis-play shows these modes as follows.

AUTO : FMA Forced Wide : FMW Forced Middle : FMM Forced Narrow : FMN

TEST MODE

7. CD Receiver Test Mode Specification When resetting to start, forced ejection of CD is prohib-

ited. When a CD is in place, the CD is not recognized whenreset.

When this key is pressed, the mechanism jumps tothe following track.

No9 No15 No10 No11 No12 No13 No22 No14 No9 (Return to the first track.)

When this key is pressed, the track goes down by onefrom the currently played track.

When a CD being played, by pressing [1] key intermittently,the mechanism can be made to jump to Track No. 28.

8. 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 and Treble are adjusted in 3 steps of -8/0/+8

with the Track Up/Down keys. Balance is adjusted in 3 steps of L15/0/R15 with the Track

Up/Down keys. Fader is adjusted in 3 steps of F15/0/R15 with the Track

Up/Down keys. Volume Offset is adjusted in 2 steps of -8/0 with theTrack

Up/Down keys.

9. Menu-related specifications A short press of the MENU key initiates the Menu mode.

Except, tape source is usually press and hold 1 second toenter the menu mode and short press initiates turn over.

Pressing the DNPP/SBF key on the remote initiates theMenu mode.

Continuous holding of a remote control key is inhibited. Contrast is adjusted in 3 steps of 0/5/10 (5x7dot), 0/4/7

(14seg) with the Track Up/Down keys.

10. Backup current measurement When the unit is reset while ACC is OFF (i.e. by turning

Back-Up ON), the MUTE terminal goes OFF in 2 secondsin place of 15 second.

12. Other specifications The line mute against times are 1 second from 10 sec-

onds when starting the test mode.

Security Forced Power ON mode (All models)

Even when the security is approved, resetting the unit whileholding the Q and 4 keys makes it possible to turn thepower ON for 30 minutes.After 30 minutes have elapsed, itis not possible to return to the previous condition unlessthe unit is reset again.

Method of registration of the security code afterEEPROM (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.3. When the message Security is displayed, press and

hold the Track Up/Down key for 1second to enter theSecurity registration mode.

4. Enter the code using the FM/AM/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 andthe message, RE-ENTER appears, so once again en-ter 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 testmode)(Note) All Clear is not applicable to the security code ofthis model.

Simplified method of clearing the security code1. While the code entry is requested, press and hold the

Track Up key for 3 seconds while holding the AUTO keypressed. (----will dissappear.)

2. Enter KCAR from the remote. 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. Security function is canceled and the unit enters the All

OFF mode.4. If you commit a mistake in the code entry, the unit en-

ters the code request mode.
