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 (earth) lead to a
metal surface of the car first.
• When your car has a built-in FM/AM antenna (aerial) in

Be sure to connect the black ground (earth) lead to a metal
surface of the car first.
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/AM 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.

• 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.
