First connect the black earth lead, then connect the orange/
white stripped, yellow, and red power input leads.

2

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/MW/SW aerial in the rear/

side glass, see “Notes on the control and power supply 
leads.”

3

This connection is only for amplifi ers. Connecting any other 
system may damage the unit.

5

Be sure to connect the black earth lead to a metal surface 
of the car fi rst.

6

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 earth lead to a metal surface 

of the car fi rst.

•  When your car has a built-in FM/MW/SW aerial in the rear/

side glass, see “Notes on the control and power supply 
leads.”

7

Be sure to connect the black earth lead to a metal surface 
of the car fi rst.

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/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 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 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 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.
