11、LOADING by pressing for at least 2 seconds, all error log information is cleared. (Display) I2C_ (Display) ERR_1, 2, 3 In “”, “OK” or ”NG” is displayed. In “”, “ ” or an error code is displayed. (*1) : 1 count is made when the panel opens to full or when a disc is loaded. Initializing AUDIO-related

12、value setting During STANDBY sourcing, by pressing key for less than 1 second, AUDIO setting values are returned to the default values. Flash ROM check 1. In order to prevent the Flash ROM (4M) equipped models to be installed with the Mask ROM (2M) panel, and to pre- vent the Mask ROM (2M) equipped

13、models to be installed with the Flash ROM (4M) panels, with the STANDBY sources during the test mode, the following display will be made according to the system -com and panel combina- tion. Flash ROM (4M) equipped model and Flash ROM (4M) panel All lights turned on OK! Mask ROM (2M) equipped model

14、and Mask ROM (2M) panel All lights turned on OK! Flash ROM (4M) equipped model and Mask ROM (2M) panel “M4P2” NG! Mask ROM (2M) equipped model and Flash ROM (4M) panel “M2P4” NG! 2. When entering the test mode, the manufacture code of the Flash ROM (4M) is read and when it is normal, FROMCHK of the

15、100th terminal (Panel -com) repeats Hi Low Hi . If the reading is abnormal, “Low” is output. If the manufacture code is normal, by pressing key for less than 1 second, the connection checks on all terminal is started. If the connections are normal, the FROMCHK terminal stops the Hi Low Hi repeating

16、and out- puts “Hi”. If the reading is abnormal, “Low” is output. TEST MODE KDC-MP628/MP7028/MP728 MP8029/W7031/W7031Y 17 3. With all lights turned on and by pressing AM key for at least 1 second, the data on the Flash ROM (4M) is initial- ized. While erasing the data, “Data_Erase.” is displayed. Not

17、e : Do not touch any key white this is in progress. When erasing is complete, “Erase_OK!” is displayed. If “Erase_NG!” is displayed, it was not possible to erase the data on the Flash ROM (4M). In this case, pressing AM key for at least 1 second again. If it is the same, then there is an abnormality

18、 with the Flash ROM. Other At Power ON, “CODE_OFF”, “CODE_ON” displays will not be made. When sourcing STANDBY, by pressing AUTO or TI key for less than 1 second, GREEN/RED of the key illumination is switched. When doing this, the triangle illumination GREEN/RED is switched along with the key illumi

19、nation. When staring up in the test mode, LINE MUTE prohibition time is set to 1 second instead of 10 seconds. While in the test mode, even when a DC offset error is de- tected, the detection information will not be written to the E2PROM. While in the test mode, even after an elapse of pre-set time,

20、 the backup memory items will not be written to the E2PROM. Information Clear mode for Test Mode, backup/installer memory, and CD mechanism error log. In the DC offset error detection information clear mode, DEMO mode operation will not be conducted. Also, in the above mode, the menu of the STANDBY

21、source will not display DEMO ON/OFF switching items. While in the test mode, and at the same time, PM_DET of the 60th terminal (System -com) is H, the following will apply to the EJECT key, regardless of whether a disc is in the unit or not. Panel full OPEN/CLOSE is conducted with a push for less th

22、an 1 second. (Protection time : 3 seconds) As far as this item is concerned, eject will be achieved by for at least 1 second push on the EJECT key. Clearing backup memory and installer memory data (Clearing E2PROM data) 1. By pressing (NEXT) key and ATT key simultaneously, reset and start the unit.

23、This will start the initialization pro- cesses for backup and installer memory data and the error log information of the CD mechanism. Abnormal ending 1 : backup/installer memory initialization : NG TEST MODE C D _ E 2 P _ _ _ : A U D I O _ E 2 P : C D _ E 2 P _ _ _ : A U D I O _ E 2 P : C D _ E 2 P

While in this mode, even after an elapse of a pre-set time, no backup memory items will be written to the E2PROM. 4. This

25、 mode is released by resetting. (What was on the last screen will not be retained.) Clearing DC offset error detection information (E2PROM data clear) 1. While simultaneously pressing down on 3 and 6 keys, reset the unit to enter the DC offset error display mode. 2. During STANDBY sourcing, the curr

26、ent DC offset error con- ditions will be displayed. When error detected : “DC_ERR” When error not detected : “DC_OK” 3. While the error conditions are being displayed, press AUTO or TI key for less than 1 second to clear the detection information. (E2PROM clear) 4. DC offset error display mode is re

27、leased by resetting. (What was on the last screen will not be retained.) 2. When initialization is complete, the following display will be made. Normal completion 18 KDC-MP628/MP7028/MP728 MP8029/W7031/W7031Y FM/AM channel space switching (KDC-MP628/MP7028/MP728/MP8029) From the Power OFF condition,

28、 while pressing 1 and 5 keys down simultaneously, press the SRC key and turn power ON. Security Forced Power ON mode While “ ” is being displayed, by resetting while pressing (NEXT) key and 4 key simultaneously, it is possible to turn the power ON for 30 minutes only. Method of clearing the programm

29、able security code (KDC-MP628/MP7028/MP728) 1. While “ ” is being displayed, press key for at least 3 seconds while pressing AUTO key. This makes “ ” display disappear. 2. Using the remote controller, input “KCAR”. Press remote controller 5 key 2 times (Input for “K”) and then press key. Press remot

30、e controller 2 key 3 times (Input for “C”) and then press key. Press remote controller 2 key once (Input for “A”) and then press key. Press remote controller 7 key 2 times (Input for “R”) and then press key. 3. The security is released and the unit enters the STANDBY mode. 4. If a wrong code is inpu

31、t, the unit goes into the Code Re- quest mode. TEST MODE How to register the security code on the “Car Au- dio Passport” after replacement of the E2PROM (KDC-MP8029/W7031/W7031Y) 1. Enter the test mode. (Refer to the section on “How to Enter the Test Mode.”) 2. Enter the MENU by long pressing (NEXT)

32、 key for one second. While “Security” is being displayed, press key for at least 1 second and enter the security registration mode. 3. Using FM / AM / / keys, enter the code. FM key : Number up / AM key : Number down key : Cursor Right / key : Cursor Left 4. Press key for at least 3 seconds to displ

33、ay “RE-EN- TER”. Then, re-enter the code using the method in above No. “3”. 5. Press key for at least 3 seconds to display “AP- PROVED”. 6. Release the test mode.
