Connection diagram  
"  To AMP REMOTE IN of an optional power 
amplifier
This connection is only for amplifiers. Connecting any other 
system may damage the unit.
Warning
If you have a power antenna (aerial) without a relay box, 
connecting this unit with the supplied power connecting 
lead 
 may damage the antenna (aerial).
Notes on the control and power supply leads
  The power antenna (aerial) control lead (blue) supplies +12 V 
DC when you turn on the tuner.
  When your car has built-in FM/MW/SW antenna (aerial) in the 
rear/side glass, connect the power antenna (aerial) control 
lead (blue) or the accessory power supply lead (red) to the 
power terminal of the existing antenna (aerial) booster. For 
details, consult your dealer.
  A power antenna (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 ground (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.
  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 amplifier are not connected correctly, “FAILURE” 
appears in the display. In this case, make sure the speaker and 
amplifier are connected correctly.
