SEL MODE DISP RDSPTY OFF/ Press the three buttons (UP button )+( button)+(Func button ). Then it is possible to select the follwing service modes. After changing over to the service mode, press the UP button and DOWN button to change 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. NORMAL MODE DELEEPROM CD-CH ERR DEL CH-ERR RUNNING DELDATA CD-ERR (UP button ) + ( button) + ( button) at the same time. : 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 this system, it is posible under the service mode to call the contents of error according to the following steps when any error has occurred. Data stored in EEPROM 1. RDS data 2. CD mechanism error cord 3. 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. Functions of the mechanism under the service mode 12 345 6 SOURCE

Focus search error In the case of focusing error after 3-way focus searching Tracking balance adjusting error In the case of time-over (1sec.) of timer TOC area searching error In the case of time-over (10sec.) of timer Reading error IN the case of time-over (30sec.) of timer 1st tracking access error In the case of time-over (10sec.) of timer Last tracking access error In the case of time-over (10sec.) of timer Q code reading error In the case of time-over (0.6sec.) of timer TEXT data reading error 04 0051 04 0052 81 0053 82 0054 82 0055 84 0059 80 0060 80 0061 80 0062 80 0063 The pickup cannot returned to the inner peripheral, and the REST switch is not turned off. The pickup cannot be returned to the outer peripheral, and the REST switch is not turned off. In case the focus cannot be searched by one set of focus searching (3-way focus searching) after disc change and focus shock, judge that the focus searching system is in error. In case tracking balance cannot be adjusted even after elapse of 1sec. following execution of the adjusting command (TBA). In case TOC area searching is not ended even after elapse of 10sec. In case reading is not ended even after elapse of 30 sec. during TOC reading action. In case the first tracking access is not ended even after elapse of 10sec. following completion of TOC reading. In case the last tracking access is not ended even after elapse of 10sec. following completion of first tracking 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. Eject error
