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 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.
• 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.
