Functions of the mechanism under the service mode
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.
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
(UP button ) + ( button) + ( button) at the same time.
DELEEPROM
: Deletion of entire EEPROM data. This mode is used when
shipping this system from factry.
CD-CH ERR
: This mode is used only when the CD changer is connected.
DEL CH-ERR
: This mode is used only when the CD changer is connected.
RUNNING
: Running mode (Do not use this mode under the servise mode)
DELDATA
: (Deletion of CD error code and RDS data)
CD-ERR
: Calling of CD mechanism error code
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.
