Prevention of accidents caused by short-circuits
To prevent the risk of accidents caused by short-circuits, connect the power supply leads (red and yellow)
only after all other wiring has been completed, and only with the ignition key in the OFF position.
Otherwise, accidental short-circuiting can lead to electric shock and to serious damage.
When a fuse has blown, check the wiring and locate the cause of the problem before replacing the fuse.
When replacing the fuse, be sure to use only a fuse of the same rating (ampere rating). Using a different
fuse or bridging the contacts with wire is highly dangerous and can lead to serious damage.
Make sure to connect all of the following leads.
Otherwise there is a risk of electric shock, damage to the equipment, or malfunction.
• Connect purple/white lead to back lamp lead of car.
• Connect orange/white lead to illumination signal lead of car.
• Connect light green lead to parking brake switch lead of car.
• Connect yellow lead to battery power supply of car.
• Connect red lead to accessory power supply of car.
• Connect black lead to metal point on car chassis.
* Do not mix up the yellow and red leads, as this will cause the memory contents to be lost.
Observe the following precautions.
Otherwise there is a risk of electric shock, damage to the equipment, or malfunction.
• Cover unused connectors with electrician's tape to prevent accidental contact.
• Route FM/AM antenna cable, bus cable, RCA interconnects, and power supply leads as far apart from
each other as possible, to prevent noise interference.
• Always grasp the connector and do not pull the cable when disconnecting the bus cable or other cables.
Otherwise the cable may become detached.
Notes on the control and power supply leads
• The power antenna control lead (blue) supplies +12 V DC when turn on the tuner.
• When your car has built-in FM / AM antenna in the rear / side glass, connect the power antenna
control lead (blue) or the accessory power input lead (red) to the power terminal of the existing
antenna booster. For details, consult your dealer.
• A power antenna 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.
