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, momentary power down, Acc OFF, Power OFF, detach the panel.

•BEEP should always function when the key is pressed.

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

● RDS automatic measurement

Conventionally, the PS display has been visually checked on the production line. This will be replaced by a new processing. The PS data will be received and the PS contents is to be verified as “RDS_TEST”. When this is verified, the P-CON terminal is forced to go OFF. (In this case, “ _ ” means blank.)

→ This will be a dedicated test mode processing.

On the P-CON, when power is turned off once and, then, turned on again, (Power OFF → ON) the unit will be restarted.

● Clearing CD mechanism information and service

information (E2PROM data clearing)

1.While pressing the [Q] key and [ATT] key, reset-start to start CD mechanism and service information initialization.

(While “– – – –“ is being displayed, power can be ON for 30 minutes.)

[CD mechanism information]

•Displays I2C communication condition

•Displays CD mechanism error log

•Displays CD loading error data.

•Displays CD ejection error data

•Displays CD time code error count data (missing count)

•Displays CD time code error count data (count not updated) [Service information]

•Displays power ON time is displayed

•Displays CD operation time

•Displays number of CD EJECT times

•Displays number of times panel was opened/closed

•Displays forced Power OFF data

2.After the initialization process is completed, the following is displayed.

When successfully completed : “CD_O_ _ _”

When finished but unsuccessful : “CD_X_ _ _”

CD mechanism information clearing is no good.

3.This mode is cancelled by resetting. (The last screen will not be retained.)

● Clearing DC offset error detection data

(E2PROM data clearing)

If DC voltage difference (DC offset error) is detected between audio power amplifier (power IC) ± outputs, “DC_ERR_” is displayed on the display. When this occurs, the audio is forcedmute and the display displays only “DC_ERR_”.

Once this product detected a DC offset error, even if it is restarted (or reset), its display displays “DC_ERR_”. However, if the error is detected while in Test Mode, it is not saved in E2PROM.

1.Press and hold [3] and [6] keys and reset-start to go into the DC offset error display mode.

(While “– – – –“ is being displayed, power can be ON for 30 minutes.)

2.While in STANDBY source, the current DC offset error condition is displayed.

When detected : “DC_ERR_ _”

When not detected: “DC_OK_ _ _”

3.While error condition is being displayed, press [AUTO] key to clear the detection data. (Clear E2PROM)

4.DC offset error display mode is cancelled by resetting. (The last screen will not be retained.)

TEST MODE

● FM/AM channel space switching

(KDC-MP5033U/MP532U only)

While power is OFF, press and hold [1] and [5] keys, and press

[SRC] key to power ON.

● IC10 (X34-) Stereo adjustment (VCO adjustment)

While in test mode and all lights are lit (STANDBY), press and hold [1] key and press [6] key for 3 seconds or longer. “VCO ADJ” will be displayed for a second.

(Adjusted data will be written on E2PROM.)

● Security

1)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.

2)How to register the security code on the “Car Audio Passport” sheet after replacing E2PROM

(IC103) (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.

3) How to clear the programmable security code

(KDC-MP532U only)

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 for “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 for “A”) and press [ ] key.

Press [7] key of the remote controller twice (Input for “R”) and press [ ] key.

3.The security is cleared and the unit enters STANDBY source.

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