ELECTRICAL CONNECTIONS
To prevent short circuits, we recommend that you disconnect the batterys negative terminal and make all electrical connections before installing the unit. If you are not sure how to install this unit correctly, have it installed by a qualified technician. Note: This unit is designed to operate on 12 volts DC, NEGATIVE ground electrical systems. If your vehicle does not have this system, a voltage inver ter is required, which can be purchased at JVC IN-CAR ENTERTAINMENT dealers. Replace the fuse with one of the specified rating. If the fuse blows frequently, consult your JVC IN-CAR ENTERTAINMENT dealer. If noise is a problem. This unit incorporates a noise filter in the power circuit. However, with some vehicles, clicking or other unwanted noise may occur. If this happens, connect the units rear ground terminal (see connection diagram) to the cars chassis using shorter and thicker cords, such as copper braiding or gauge wire. If noise still persists, consult your JVC IN-CAR ENTERTAINMENT dealer. Maximum input of the speakers should be more than 45 watts at the rear and 45 watts at the front, with an impedance of 4 to 8 ohms. Be sure to ground this unit to the cars chassis. The heat sink becomes very hot after use. Be careful not to touch it when removing this unit.

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

CD-CH ERR

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.

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. Error codes
