The numbers in the list are keyed to those in the
instructions.
Caution
Handle the bracket 1 carefully to avoid injuring
your fingers.
Cautions
•This unit is designed for negative earth 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
earth 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 earth wires to a common earth
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.
Connection example (2)
Notes (2-A)
• Be sure to connect the earth 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.
Connection diagram (3)
1 To a metal surface of the car
First connect the black earth lead, then connect
the yellow and red power input leads.
2 To the power aerial control lead or power
supply lead of aerial booster amplifier
Notes
• It is not necessary to connect this lead if there
is no power aerial or aerial booster, or with a
manually-operated telescopic aerial.
• When your car has a built-in FM/AM (MW/SW)
aerial 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 +12 V power terminal which is energised
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 earth lead to it
first.
• When your car has a built-in FM/AM (MW/SW)
aerial in the rear/side glass, see “Notes on the
control and power supply leads.”
5 To the +12 V power terminal which is energised
at all times
Be sure to connect the black earth lead to it first.
Notes on the control and power supply leads
• The power aerial control lead (blue) supplies +12 V
DC when you turn on the tuner.
• When your car has built-in FM/AM (MW/SW) aerial
in the rear/side glass, connect the power aerial
control lead (blue) or the accessory power input
lead (red) to the power terminal of the existing
aerial booster. For details, consult your dealer.
• A power aerial without relay box cannot be used
with this unit.
Memory hold connection
When the yellow power input lead is connected,
power will always be supplied to the memory circuit
even when the ignition key is turned off.
Notes on speaker connection
• Before connecting the speakers, turn the unit off.
• Use speakers with an impedance of 4 to 8 ohms,
and with adequate power handling capacities to
avoid its damage.
• Do not connect the speaker terminals to the car
chassis, or connect the terminals of the right
speakers with those of the left speaker.
• Do not connect the earth lead of this unit to the
negative (–) terminal of the speaker.
• Do not attempt to connect the speakers in parallel.
• Connect only passive speakers. Connecting active
speakers (with built-in amplifiers) to the speaker
terminals may damage the unit.
