A
To  AMP REMOTE IN of an optional power amplifier
This connection is only for amplifiers. Connecting any other
system may damage the unit.
B
To  the interface cable of a car telephone
Warning
If you have a power aerial without a relay box, connecting this unit
with the supplied power connecting lead 7 may damage the aerial.
Notes on the control leads
• The power aerial control lead (blue) supplies +12 V DC when you
turn on the tuner, or when you activate the AF (Alternative
Frequency) or TA (Traffic Announcement) function.
• When your car has built-in FM/MW/LW 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 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.
