Cautions:

¡Check the connectors provided on your car (see note on page 4 and 5) before connecting the system.
¡This unit is designed for use in a car having a 12-volt negative ground battery system.
¡To prevent damage to the unit, be sure to follow the connection diagram below.
¡Strip about 5 mm of the lead ends for connection (only non-ISO connector cords).
¡Do not insert the power connector into the unit until the wiring is completed.
¡Be sure to insulate any exposed wires to prevent short circuiting with the car chassis. Bundle all cables, and prevent

cable terminals from touching any metal parts.

¡This unit can be connected to an optional CD changer (CX-DP9061/DP9060EN, CX-DP88N, CX-DP801/DP803EN or

CX-DP601EN) and optional extension cord.

¡For details consult your nearest authorized Panasonic Dealer.
