: 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.
