ɠ  To AMP REMOTE IN of an optional power 
amplifi er
This connection is only for amplifi ers. Connecting any other 
system may damage the unit.
ɡ  To the interface cable of a car telephone
ɢ  To a car’s illumination signal
Be sure to connect the black ground lead to a metal surface 
of the car fi rst.
ɣ  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 energized at all times.
  Be sure to connect the black ground lead to a metal 
surface of the car fi rst.
  When your car has a built-in FM/AM antenna in the rear/
side glass, see “Notes on the control and power supply 
leads.”
ɤ  To the +12 V power terminal which is 
energized at all times
Be sure to connect the black ground lead to a metal surface 
of the car fi rst.
Notes on the control and power supply leads
  The power antenna control lead (blue) supplies +12 V DC 
when you turn on the tuner.
  When your car has built-in FM/AM antenna in the rear/side 
glass, connect the power antenna control lead (blue) or the 
accessory power input lead (red) to the power terminal of the 
existing antenna booster. For details, consult your dealer.
  A power antenna without a 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 
switch 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 ground 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 amplifi ers) to the speaker terminals may damage 
the unit.
  To avoid a malfunction, do not use the built-in speaker leads 
installed in your car if the unit shares a common negative (–) 
lead for the right and left speakers.
  Do not connect the unit’s speaker leads to each other.
Note on connection
If speaker and amplifi er are not connected correctly, “Failure” 
appears in the display. In this case, make sure the speaker and 
amplifi er are connected correctly.
Connection example
Notes (
ǵ-A)
  Be sure to connect the ground lead before connecting the 
amplifi er.
  The alarm will only sound if the built-in amplifi er is used.
Tip (
ǵ-B- )
For connecting two or more CD/MD changers, the source 
selector XA-C40 (not supplied) is necessary.

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.”
