TEST MODE

●How to enter the test mode

Press and hold the [1] and [3] keys and reset. (While “– – – –” is being displayed, power can be ON for 30 minutes.)

●How to clear the test mode

Reset. (Not cancelled by Power OFF or ACC OFF.)

●Test mode default condition

• Source is STANDBY.

• Display lights are all turned on.

• The volume is at -10dB (The display is 30).

• LOUD is OFF.

• CRSC is off regardless of the availability of switching function.

• SYSTEM Q is NATURAL (=FLAT).

• BEEP always functions when the key is pressed while in sources other than STANBY.

●Specification of test mode for tuner

K3I forced switching

• [6] key in TUNER mode s witches A UTO → forced narrow → forced middle → forced wide.

• When K3I AUTO, if PTY dot is off, filter value read from FAST4 is displayed. If force-set, PTY dot is lit and the setting value is displayed. (“Forced/AUTO” is determined by the PTY dot being on or off.)

Wide : “FMW 98.1” Middle : “FMM 98.1” Narrow : “FMN 98.1”

RDS automatic measurement (KDC-W4534/Y only)

• TUNER mode [4] key frequency shall be 98.3MHz.

• When RDS data (“RDS TEST”) is received, P.CON is set to OFF.

●CD receiver test mode specification

• Display mode default setting shall be P-TIME.

•Forced ejection is prohibited while reset-starting. Note that CD is not to be recognized by reset while it is inserted.

•Jumps to the next tracks by pressing the [ ] key.

No.9 → No.15 → No.10 → No.11 → No.12 → No.13 → No.22 → No.14 → No.9 (Recursive) Note that when playing a MP3 / WMA / AAC disc with 8 files or less, the disc is played from the 1st track in the regular order.

• Pressing the [ ] key goes back by 1 track from the track being played.

• When CD is the source, press the [1] key to jump to No.28.

• When CD is the source, press the [2] key to jump to No.14.

• When CD is the source, press the [6] key to jump to No.15. At this time, the volume value is set to 25.

●AUDIO adjust mode

• Press the [AUD] key and enter the audio adjustment mode.

•Press the remote control [∗] key and [AUD] key to go into the audio adjustment mode.

• Both AUDIO FUNCTION MODE and SETUP MODE adjustment items are included.

• By pressing [AUD] and [FM] keys, switch the item to be adjusted in the following order. (Only in forward rotation) The default item shall be Fader, and then the item is forwarded in the following order: Balance → Bass Level → Middle Level → T reble Level.

• Continuous forwarding by remote control is prohibited.

•Fader is adjusted by the VOL knob and [ ] / [ ] keys in 3 steps: R15 ↔ 0 ↔ F15. (Default value: 0)

• Balance is adjusted by the V OL knob and [ ] / [ ] keys in 3 steps: L15 ↔ 0 ↔ R15. (Default value: 0)

• Bass/Middle/T reb le are adjusted b y the VOL knob and [ ] / [ ] keys in 3 steps: -8 ↔ 0 ↔ +8. (Default value: 0)

•Volume Offset is adjusted by the VOL knob and [ ] / [ ] keys in 2 steps: -8 ↔ 0. (Default value: 0)

• Loudness ON/OFF is adjusted by the V OL knob and [ [ ] keys in 2 steps: OFF ↔ ON. (Default value: OFF)

●MENU

• Press [Q] key to enter the MENU.

• Press the remote control [DNPP/SBF] key to enter the MENU.

• Continuous forwarding by remote control is prohibited.

●Backup current measurement

If reset while in Acc OFF (Back Up ON) condition, MUTE terminal goes off 2 seconds later, rather than 15 seconds. (During this time, the CD mechanism does not function.)

● Fluorescent indicator tube (ED1) short-checking

•When the source is STANDBY, press [ATT] key to switch the process in the following order.

1. All lights off.

2. Every 125m sec, light the odd and even number of the

grid with the largest numbers.

3. Light only odd number terminals.

4. Light only even number terminals.

5. All lights on.

∗After the step 5 above, the process goes back to the

step 1 and then repeats the steps.

● Initializing AUDIO-related setting value

Press the [ ] key in the STANDBY source and reset the AUDIO setting value to the test mode default value.

● Other

• When Power ON, do not display “CODE_OFF” and “CODE_ON”.

• When the source is STANDBY, press [AUTO] or [TI] key to switch key illumination GREEN/RED. (in the model with ILLUMI switching function)

• When star ted in Test Mode, duration of prohibiting LINE MUTE shall be changed from 10 seconds to 1 second.

• While in Test Mode, serial number is not written with a serial-number-writing jig.

• When in Test Mode, when DC offset error detection is run, the detection information is not written into the E2PROM.

• DEMO mode shall not be operated while in Test Mode, CD Mechanism Error Log Data Clearing Mode, or DC Offset Error Detection Data Clearing Mode.

Security

•How to enter the forced POWER ON mode

While “– – – –” is being displayed, while simultaneously pressing [Q] key and [4] key, press [RESET] button, With this, it is possible to turn the power on for 30 minutes only.

•How to register the security code on the “Car Audio Passport” sheet after replacing E2PROM (IC11) (For models of destination “E” or “M”)

1. Enter the test mode. (Refer to “How to enter the test

mode”.)

2. In the test mode, press [Q] key to enter the MENU mode.

When “CODE_SET” is displayed, press [ ] key for 1 second or longer to enter the security registration mode.

3. Input the security code, using [FM] / [AM] / [ ] / [ ]

keys. [FM] key: number up / [AM] key: number down [ ] key: cursor to right / [ ] key: cursor to left

4. After inputting the code, press [ ] key for 3 seconds or

longer which causes “RE-ENTER” to be displayed. This is for “confirming” the code. Use the method in the step 3 to re-enter the code.

5. Then, press [ ] key for 3 seconds or longer, which will

display “APPROVED”. This completes the security code

registration.

6. Release the test mode. (Refer to “How to clear the test mode”.) ∗All clear cannot be used to clear the security code.

•How to clear the programmable security code (For models of destination “K”)

∗ Operation 1

1. While “– – – –” is being displayed, press [ ] key for 3

seconds or longer while pressing the [AUTO] key. This makes the “– – – –” display disappear.

2. Input “KCAR”, using the remote controller.

Press [5] key of the remote controller twice (Input f or “K”) and press [ ] key. Press [2] key of the remote controller 3 times (Input for “C”) and press [ ] key. Press [2] key of the remote controller once (Input f or “A”) and press [ ] key. Press [7] key of the remote controller twice (Input f or “R”) and press [ ] key.

3. The security is cleared and the unit enters STANDBY

source.

4. If wrong codes are input, “– – – –” will be display ed again.

∗ Operation 2

1. After code has been registered, in STANDBY source,

press and hold the [Q] key for 1 second or longer to go into the MENU. While “CODE_CLR” is displayed, press the [

] keys for 1 second or longer to cancel the secu-

rity code.

2. Input pre-registered code, using [FM] / [AM] / [ ] / [ ]

keys. [FM] key: numbers go up / [AM] key: numbers go down [ ] key: cursor moved to the right / [ ] key: cursor moved to the left

3. Press the [ ] key for 3 seconds or longer and “CLEAR”

is displayed.

4. When the input code is not registered, “ERROR” is dis-

played. Go back to the step 2 and input the code again.

●Clearing CD mechanism information and service

information (Clearing E2PROM data)

1. While pressing the [Q] key and [A TT] k e y, reset-start to start CD mechanism and service information initialization. (While “– – – –” is being displayed, power can be ON for 30 minutes.) [CD mechanism information]
