Cautions
· This unit is designed for negative ground 12 V
DC operation only.
· Do not get the wires under a screw, or caught
in moving parts (e.g. seat railing).
· Before making connections, disconnect the
ground terminal of the car battery to avoid
short circuits.
· Connect the yellow and red power input leads
only after all other leads have been connected.
· Run all ground wires to a common ground
point.
· Be sure to insulate any loose unconnected
wires with electrical tape for safety.
Notes on the power supply cord (yellow)
· When connecting this unit in combination with
other stereo components, the connected car
circuit's rating must be higher than the sum of
each component's fuse.
· When no car circuits are rated high enough,
connect the unit directly to the battery.
Parts Iist (1)
The numbers in the list are keyed to those in the
instructions.
Caution
Handle the bracket 1 carefully to avoid injuring
your fingers.

Connectionexample(2)
Notes (2-A)
· Be sure to connect the ground cord before
connecting the amplifier.
· If you connect an optional power amplifier and
do not use the built-in amplifier, the beep
sound will be deactivated.
Tip (2-B-
)
For connecting two or more changers, the source
selector XA-C30 (optional) is necessary.
Connectiondiagram(3)
1 To a metal surface of the car
First connect the black ground lead, then
connect the yellow and red power input
leads.
2 To the power antenna control lead or power
supply lead of antenna booster amplifier
Notes
· It is not necessary to connect this lead if
there is no power antenna or antenna
booster, or with a manually-operated
telescopic antenna.
· When your car has a built-in FM/AM
antenna in the rear/side glass, see "Notes
on the control and power supply leads."
3 To AMP REMOTE IN of an optional power
amplifier
This connection is only for amplifiers.
Connecting any other system may damage
the unit.
4 To the interface cable of a car telephone
5 To the +12 V power terminal which is
energized in the accessory position of the
ignition key switch
Notes
· If there is no accessory position, connect to
the +12 V power (battery) terminal which is
energised at all times.
Be sure to connect the black ground to it
first.
· When your car has a built-in FM/AM
antenna in the rear/side glass, see "Notes
on the control and power supply leads."
6 To the +12 V power terminal which is
energised at all times
Be sure to connect the black ground to it
first.
