Press the three buttons (UP button )+( button)+(Func button ). Then it is possible to select the follwingservice modes. After changing over to the service mode, press the UP button and DOWN button tochange the mode. For executing the respective service modes, press the SEL button.With the service mode 2 , it is possible to call the error codes of the mechanism.

: Deletion of entire EEPROM data. This mode is used when shipping this system from factry.

: This mode is used only when the CD changer is connected.

: This mode is used only when the CD changer is connected.

: Running mode (Do not use this mode under the servise mode)

: (Deletion of CD error code and RDS data)

: Calling of CD mechanism error code

With the three error modes stored in maximum in the internal memory of the mechanism in the body of thissystem, it is posible under the service mode to call the contents of error according to the following steps whenany error has occurred.

Data stored in EEPROM

1. RDS data2. CD mechanism error cord3. Station name (to be input by user)4. DISC name (to be input by user)5. AUX input name (application only to KD-LX30) *Any data 3 to 5 above should not be deleted.

The pickup cannot returned to the innerperipheral, and the REST switch is not turned off.The pickup cannot be returned to the outerperipheral, and the REST switch is not turned off.In case the focus cannot be searched by one setof focus searching (3-way focus searching) afterdisc change and focus shock, judge that the focussearching system is in error.In case tracking balance cannot be adjusted evenafter elapse of 1sec. following execution of theadjusting command (TBA).

In case TOC area searching is not ended even afterelapse of 10sec.In case reading is not ended even after elapse of 30sec. during TOC reading action.

In case the first tracking access is not ended evenafter elapse of 10sec. following completion of TOCreading.In case the last tracking access is not ended evenafter elapse of 10sec. following completion of firsttracking under the RUNNING mode.In case the Q code cannot be read for 0.6sec. during playing TOC program area.

In case all TEXT data cannot be read.
